The legalization of small scale mining in Colombia

Directory of Open Access Journals (Sweden)

Alexandra Urán

2013-11-01

Full Text Available The following article presents conceptual and analytical elements that allow us to broaden the debate about the legalization of the mining in Colombia. Looking for items to be able to propose alternatives in order to consolidate a new mining process socially and environmentally sustainable, claiming the value of the ancestral practices and forms of the redistributive production. To this end, it is necessary to start with the discussion of the concepts of formalization and legality, so that we can generate a theoretical framework that will allow us to explore such delicate matter, we will continue to make the framework socio-political, in which it is based that strategy. Then there is a brief context of thereformulation of legal mining, focusing our attention particularly standards which involves or has effects on artisanal mining and/or small-scale mining. There we will find ourselves with a debate on the typology of the mining and the current difficulties to define schemasof legalization or formalization of small-scale mining in Colombia. To conclude with a proposal to formalize as a mechanism of transition to an administrative system - legislativethat will connect more effectively with the realities and skills of the ethnic communities that practice small-scale mining.

SOMA: A Proposed Framework for Trend Mining in Large UK Diabetic Retinopathy Temporal Databases

Science.gov (United States)

Somaraki, Vassiliki; Harding, Simon; Broadbent, Deborah; Coenen, Frans

In this paper, we present SOMA, a new trend mining framework; and Aretaeus, the associated trend mining algorithm. The proposed framework is able to detect different kinds of trends within longitudinal datasets. The prototype trends are defined mathematically so that they can be mapped onto the temporal patterns. Trends are defined and generated in terms of the frequency of occurrence of pattern changes over time. To evaluate the proposed framework the process was applied to a large collection of medical records, forming part of the diabetic retinopathy screening programme at the Royal Liverpool University Hospital.

West Khasi Hills District of Meghalaya is identified as having a large and rich deposits of Uranium. However, actual extraction on a commercial scale that may lead to an increase in the socio-economic development of the state in particular and the country in general, is yet to be undertaken. This is due to lack of any baseline environmental survey giving rise to speculative information and causing a fear psychosis in the minds of the locals populace about the negative effects of Uranium mining. A preoperational survey and environmental monitoring of the proposed mining sites and its adjacent areas would establish the baseline status of the natural radioactivity and some chemical constituents in different environmental matrices via. air, water, soil, biota and aquatic ecosystems. The North Eastern Hill University, Shillong, Meghalaya has undertaken the Project funded by DST and BRNS, Department of Atomic Energy, Govt. of India which aims to provide baseline environmental data on ambient air, water and soil quality in and around the proposed Uranium mining site of Domiasiat, West Khasi Hills in the state of Meghalaya. Trace elements (elements like Mg, Zn, Ca, K, Na, Se, As, Fe, Cu, Co, Cr, Ni, Pb, Cd, Mn etc) and the status of the activity in the samples are determined. (author)

Preoperational assessment of solute release from waste rock at proposed mining operations

International Nuclear Information System (INIS)

Lapakko, Kim A.

2015-01-01

Highlights: • Modeling to estimate solute release from waste rock at proposed mines is described. • Components of the modeling process are identified and described. • Modeling inputs required are identified and described. • Examples of data generated and their application are presented. • Challenges inherent to environmental review are identified. - Abstract: Environmental assessments are conducted prior to mineral development at proposed mining operations. Among the objectives of these assessments is prediction of solute release from mine wastes projected to be generated by the proposed mining and associated operations. This paper provides guidance to those engaged in these assessments and, in more detail, provides insights on solid-phase characterization and application of kinetic test results for predicting solute release from waste rock. The logic guiding the process is consistent with general model construction practices and recent publications. Baseline conditions at the proposed site are determined and a detailed operational plan is developed and imposed upon the site. Block modeling of the mine geology is conducted to identify the mineral assemblages present, their masses and compositional variations. This information is used to select samples, representative of waste rock to be generated, that will be analyzed and tested to describe characteristics influencing waste rock drainage quality. The characterization results are used to select samples for laboratory dissolution testing (kinetic tests). These tests provide empirical data on dissolution of the various mineral assemblages present as waste rock. The data generated are used, in conjunction with environmental conditions, the proposed method of mine waste storage, and scientific and technical principles, to estimate solute release rates for the operational scale waste rock. Common concerns regarding waste rock are generation of acidic drainage and release of heavy metals and sulfate. Key solid

I have been asked to comment on 'how to address social concerns' in my capacity as the project manager for the City of Toronto's Toronto Integrated Solid Waste Resource Management (TIRM) Process, which was initiated in 1997 and concluded in the Fall of 2000. Inherent in this request is the goal of learning from a non-nuclear procurement process in order to offer insights for those working in the field on the short- and long-term management of nuclear waste. In particular, I have been asked to comment on the learning experience from the proposed engagement of the Adams Mine Landfill that became the focus of an intense four-day debate before Toronto's City Council and was propelled into international news linked to Toronto's Olympic bid. I would like to extend my thanks to Natural Resources Canada for their support of my participation in the NEA Conference. The opinions in this paper are those of the author and not those of the City of Toronto. (author)

Global Mining and the Uneasy Neoliberalization of Sustainable Development

Directory of Open Access Journals (Sweden)

Matthew Himley

2010-10-01

Full Text Available As transnational mining firms have sought to position themselves as drivers of sustainable development, a key component of their efforts has been the implementation of social development programs in their areas of operation. This paper situates the expansion of corporate-led development in the mining sector as part of an ongoing reconfiguration of the frameworks and processes through which mineral production is governed, interpreting such initiatives as illustrative of “roll-out” neoliberalization. Based on an analysis of firm-led development at the Pierina gold mine in Andean Peru, I explore how the mining company has been able to advance a version of sustainability broadly compatible with contemporary large-scale mining. Taking on the role of development agent, however, is not an uncomplicated endeavor in that it has left the firm subject to escalating development claims from nearby populations. In this context, I raise the question of whether the mining industry’s adoption of notions of partnership and participation amounts to a strategy for diffusing responsibility when necessary and deflecting the claims of affected communities.

Mined-out land

International Nuclear Information System (INIS)

Reinsalu, Enno; Toomik, Arvi; Valgma, Ingo

2002-01-01

Estonian mineral resources are deposited in low depth and mining fields are large, therefore vast areas are affected by mining. There are at least 800 deposits with total area of 6,000 km 2 and about the same number of underground mines, surface mines, peat fields, quarries, and sand and gravel pits. The deposits cover more than 10% of Estonian mainland. The total area of operating mine claims exceeds 150 km 2 that makes 0.3 % of Estonian area. The book is written mainly for the people who are living or acting in the area influenced by mining. The observations and research could benefit those who are interested in geography and environment, who follow formation and look of mined-out landscapes. The book contains also warnings for careless people on and under the surface of the mined-out land. Part of the book contains results of the research made in 1968-1993 by the first two authors working at the Estonian branch of A.Skochinsky Institute of Mining. Since 1990, Arvi Toomik continued this study at the Northeastern section of the Institute of Ecology of Tallinn Pedagogical University. Enno Reinsalu studied aftereffects of mining at the Mining Department of Tallinn Technical University from 1998 to 2000. Geographical Information System for Mining was studied by Ingo Valgma within his doctoral dissertation, and this book is one of the applications of his study

Influence of Government economic policies on mining legislation

Energy Technology Data Exchange (ETDEWEB)

Jakob, K F

1980-01-01

As we know from experience, the relation between state and economy is characterized by more or less strong tensions. The following three groups have always claimed the right to dispose of mineral resources: the state - in former times the sovereign -, the landowners, and the mining industry. The first one has based his claim on his official power and has taken the view that he alone could protect the interests of the general public in winning mineral resources. The second ones have relied on their titles to real estates which basically cover unlimited depth. With the intent to work the mines, the mining industry refers to its know-how, performance and readiness, thus alleging that they would serve the national economy best. The historical development of mining laws has finally been characterized by a shift in priorities within these naturally strained relations which exist between state, landowners, and mining industry. It is examined how the emphasis has been shifted in this relationship in the course of time, with special consideration of the relationship between state and mining industry. Which rules of law the legislator intends to make with regard to mining laws will always depend on the question as to which economic policy the state intends to pursue.

Warranty claim analysis considering human factors

International Nuclear Information System (INIS)

Wu Shaomin

2011-01-01

Warranty claims are not always due to product failures. They can also be caused by two types of human factors. On the one hand, consumers might claim warranty due to misuse and/or failures caused by various human factors. Such claims might account for more than 10% of all reported claims. On the other hand, consumers might not be bothered to claim warranty for failed items that are still under warranty, or they may claim warranty after they have experienced several intermittent failures. These two types of human factors can affect warranty claim costs. However, research in this area has received rather little attention. In this paper, we propose three models to estimate the expected warranty cost when the two types of human factors are included. We consider two types of failures: intermittent and fatal failures, which might result in different claim patterns. Consumers might report claims after a fatal failure has occurred, and upon intermittent failures they might report claims after a number of failures have occurred. Numerical examples are given to validate the results derived.

2006-01-01

Natural radiation sources contribute the largest component to the total effective dose received by the human population. Among these sources, natural background gamma radiation shares a noteworthy amount. The present study aims at the establishment of baseline environmental gamma radiation data in the environs of proposed uranium mining areas of Andhra Pradesh, India. To this end, a systematic study has been undertaken using Thermoluminescence (T.L.) dosimeters and G.M. (Geiger - Muller) tube based survey meter. These levels are estimated both indoors and outdoors in the study area covering about 23 villages surrounding the proposed mining sites. The estimated external gamma radiation levels (air kerma) varied from 0.605 to 4.39 mGy.y -1 . The mean indoor to outdoor radiation level ratio is found to be 1.1 ± 0.1. The estimated mean equivalent doses due to external background radiation in the villages of the study area range from 1.03 to 2.83 mSv.y -1 with a mean of 2.34 ± 0.39 mSv.y -1 . (authors)

Adequate visual function has a strong impact on the quality of life of people. Several foods and food components have been hypothesized to play a role in the maintenance of normal visual function and in the prevention of eye diseases. Some of these foods/food components have been the object of a request of authorization for use of health claims under Articles 13(5) or 14 of the Regulation (EC) 1924/2006. Most of these requests have received a negative opinion from the European Food Safety Authority (EFSA) due to the choice of inappropriate outcome variables (OVs) and/or methods of measurement (MMs) applied in the studies used to substantiate the claims. This manuscript refers to the collection, collation and critical analysis of OVs and MMs related to vision. Guidance document and requests for authorization of health claims were used to collect OVs and MMs related to vision. A literature review was performed to critically analyse OVs and MMs, with the aim of defining their appropriateness in the context of a specific claimed effect related to vision. The results highlight the importance of adequate choices of OVs and MMs for an effective substantiation of claims related to visual function. PMID:29443929

Treating mine water

Energy Technology Data Exchange (ETDEWEB)

Matlak, E S; Kochegarova, L V; Zaslavskaya, I Yu

1980-10-01

Taking into account the negative influence of mine waters with suspended matter on the natural environment on the surface, the maximum treatment of mine water underground, is proposed. It is noted that full treatment of mine water, using conventional filtration methods, would be rather expensive, but a limited treatment of mine water is possible. Such treated mine water can be used in dust suppression and fire fighting systems. Mine water treated underground should be free of any odor, with pH level ranging from 6 to 9.5, with suspended matter content not exceeding 50 mg/l and coli-titre not less than 300 cm$SUP$3. It is suggested that water treatment to produce water characterized by these parameters is possible and economical. Recommendations on construction of underground sedimentation tanks and channels, and a hydraulic system of cleaning sedimentation tanks are proposed. The settling would be stored underground in abandoned workings. (2 refs.) (In Russian)

Formulation of Generic Simulation Models for Analyzing Construction Claims

Directory of Open Access Journals (Sweden)

Rifat Rustom

2012-11-01

Full Text Available While there are several techniques for analyzing the impact of claims on time schedule and productivity,very few are considered adequate and comprehensive to consider risks and uncertainties.A generic approach for claims analysis using simulation is proposed. The formulation of the generic methodology presented in this paper depends on three simulation models;As-Planned Model (APM,As-Built Model (ABM, and What-Would-HaveBeenModel(WWHBM. The proposed generic methodology as presented in this paper provides a good basis as a more elaborate approach to better analyze claims and their impacts on project time and productivity utilizing discrete event simulation.The approach proposed allows for scenario analysis to account for the disputed events and workflow disruptions. The proposed models will assist claimants in presenting their cases effectively and professionally.

Sequential Pattern Mining of Electronic Healthcare Reimbursement Claims: Experiences and Challenges in Uncovering How Patients are Treated by Physicians

Energy Technology Data Exchange (ETDEWEB)

Pullum, Laura L [ORNL; Ramanathan, Arvind [ORNL; Hobson, Tanner C [ORNL

2015-01-01

We examine the use of electronic healthcare reimbursement claims (EHRC) for analyzing healthcare delivery and practice patterns across the United States (US). We show that EHRCs are correlated with disease incidence estimates published by the Centers for Disease Control. Further, by analyzing over 1 billion EHRCs, we track patterns of clinical procedures administered to patients with autism spectrum disorder (ASD), heart disease (HD) and breast cancer (BC) using sequential pattern mining algorithms. Our analyses reveal that in contrast to treating HD and BC, clinical procedures for ASD diagnoses are highly varied leading up to and after the ASD diagnoses. The discovered clinical procedure sequences also reveal significant differences in the overall costs incurred across different parts of the US, indicating a lack of consensus amongst practitioners in treating ASD patients. We show that a data-driven approach to understand clinical trajectories using EHRC can provide quantitative insights into how to better manage and treat patients. Based on our experience, we also discuss emerging challenges in using EHRC datasets for gaining insights into the state of contemporary healthcare delivery and practice in the US.

Mining in urban areas: methodological proposal for the identification and mediation of socio-environmental conflicts

OpenAIRE

Bacci,Denise de La Corte; Diniz,Tânia Maria Ramos de Godoi

2013-01-01

The conflicts generated by mining in urban areas are due to several reasons. In this paper we sought to identify the social actors and the dynamics of conflicts in the northwestern region of the São Paulo Municipality. This area presents aspects of environmental preservation, quarry activities, and dense urbanization. To minimize/solve these conflicts, strategies are proposed based on Social Learning methodologies.

Perils of project development on public land open to mining

International Nuclear Information System (INIS)

Jacobs, W.R.

1991-01-01

Conducting a government project on public land open to the general mining laws can result in added costs, legal entanglements, schedule uncertainties, and the potential for unanticipated safety issues and concerns due to interactions with mining claimants. Planning for such projects must include a careful assessment of not only land access needs and restrictions, but also possible scenarios for conflict with activities authorized under the general mining laws throughout the life of the project. It is essential to have a thorough knowledge of the applicable mining laws and how they are currently being interpreted and applied by the responsible regulatory authorities and land managers. The Yucca Mountain Project approach to land access, problems encountered with mining claims filed under the Mining Law of 1872, and the lessons learned from these experiences are discussed in this paper

Uranium exploration, mining and milling proposal, Navajo Indian Reservation, New Mexico

International Nuclear Information System (INIS)

Babby, W.D.

1974-01-01

The Secretary of the Interior has been requested to approve an exploration permit and mining lease which are part of a uranium exploration, mining, and milling Agreement, negotiated between the Navajo Tribe and the Exxon Corporation. The exploration area is a 400,000 acre tract located on the Navajo Reservation in San Juan County, New Mexico. If uranium ore in sufficient quantities to warrant development is discovered, Exxon is authorized to take a total of 51,200 acres to lease for mining, of which only 5,120 surface acres may be used for mining and milling purposes. While all exploration and predevelopment costs prior to mining must be borne by Exxon, the Navajo Tribe has reserved the right to participate in the venture on either a royalty basis or as a partner holding up to a 40 percent working interest. Impacts resulting from exploration will include disturbance of soils and vegetation and air quality degradation resulting from the vehicular movement and the operation of drilling equipment. If mining and milling takes place significant environmental impacts include: sub-surface water depletion, soils and vegetation disturbance, air quality degradation, interruption of the wildlife habitat, population increases, increased demands on community services and facilities, and disruption of established lifestyles and social patterns. Low levels of radioactive emissions will be found at mine and mill sites. Income and employment opportunities from the project to the Navajo Tribe, Navajo people, and the entire San Juan County community will be significant

Analysis of long-term groundwater dispersal of contaminants from proposed Jabiluka Mine tailing repositories. Supervising Scientist report 143

International Nuclear Information System (INIS)

Kalf, F.; Dudgeon, C.

1999-01-01

The Jabiluka project area lies within a 73 km 2 mining lease near the edge of Kakadu National Park, a World Heritage area of approximately 19 800 km 2 . Existing approvals require all tailings to be disposed of underground. The current proposal is to add cement to the partially dewatered tailings to form a paste which would be deposited and allowed to set in the underground mine voids and specially excavated underground silos. Fears have been expressed that the park will suffer long term adverse effects as a result of the mining operation. Contamination of groundwater is one possibility to be considered. This report describes and gives the results of an investigation into the movement of the potential contaminants, magnesium sulphate, manganese, radium and uranium from mine tailings by groundwater flow towards the park after disposal of tailings underground in the mine voids and silos. The proposed silos would be constructed to hold the balance of the tailings which could not be accommodated in the mine workings. The tops of the silos would be approximately 100 m below ground surface. Tailings stored in mine voids would have an even greater average cover, with a minimum of approximately 90 m. Groundwater flow in the vicinity of the mine is topographically controlled. Groundwater flow and consequent contaminant transport from the mine site towards the Magela floodplain has been modelled to predict the concentrations of contaminants to be expected along the flow paths. The availability of data on aquifer properties and the nature of the drainage pattern led to the use of a two dimensional finite element numerical model of flow along the paths described above. A three dimensional numerical solute transport model applied in a single layer was used to predict relative concentrations along the flow paths of contaminants leached from the tailings repositories. An analytical contaminant transport model was used in conjunction with a numerical model to determine the effects

Beyond genes, proteins, and abstracts: Identifying scientific claims from full-text biomedical articles.

Science.gov (United States)

Blake, Catherine

2010-04-01

Massive increases in electronically available text have spurred a variety of natural language processing methods to automatically identify relationships from text; however, existing annotated collections comprise only bioinformatics (gene-protein) or clinical informatics (treatment-disease) relationships. This paper introduces the Claim Framework that reflects how authors across biomedical spectrum communicate findings in empirical studies. The Framework captures different levels of evidence by differentiating between explicit and implicit claims, and by capturing under-specified claims such as correlations, comparisons, and observations. The results from 29 full-text articles show that authors report fewer than 7.84% of scientific claims in an abstract, thus revealing the urgent need for text mining systems to consider the full-text of an article rather than just the abstract. The results also show that authors typically report explicit claims (77.12%) rather than an observations (9.23%), correlations (5.39%), comparisons (5.11%) or implicit claims (2.7%). Informed by the initial manual annotations, we introduce an automated approach that uses syntax and semantics to identify explicit claims automatically and measure the degree to which each feature contributes to the overall precision and recall. Results show that a combination of semantics and syntax is required to achieve the best system performance. 2009 Elsevier Inc. All rights reserved.

Recent Developments in Microbiological Approaches for Securing Mine Wastes and for Recovering Metals from Mine Waters

Directory of Open Access Journals (Sweden)

D. Barrie Johnson

2014-04-01

Full Text Available Mining of metals and coals generates solid and liquid wastes that are potentially hazardous to the environment. Traditional methods to reduce the production of pollutants from mining and to treat impacted water courses are mostly physico-chemical in nature, though passive remediation of mine waters utilizes reactions that are catalysed by microorganisms. This paper reviews recent advances in biotechnologies that have been proposed both to secure reactive mine tailings and to remediate mine waters. Empirical management of tailings ponds to promote the growth of micro-algae that sustain populations of bacteria that essentially reverse the processes involved in the formation of acid mine drainage has been proposed. Elsewhere, targeted biomineralization has been demonstrated to produce solid products that allow metals present in mine waters to be recovered and recycled, rather than to be disposed of in landfill.

Mining and its effects on the environment

International Nuclear Information System (INIS)

Kadlec, J.

1996-01-01

The article advocates mineral resource mining against fierce environmentalists who can see only the adverse aspects of this branch of industry. The following concepts are argued against: endangerment and permanent disturbance of the environment due to the mining and processing of mineral raw materials; excessive exploitation and selling-out of Czech national mineral resources; and inefficiency of administrative tools to protect Czech mineral resources and environment. It is concluded that mineral raw materials mining does not endanger the environment more than other anthropogenic activities do. Mining on its own is not responsible for the current poor condition of the environment in the Czech Republic, nor is it a source of permanent disturbance of the environment, as often unjustly claimed. The permanently sustainable development programme, referred to in the Environmental Protection Act, should only mitigate some adverse aspects of anthropogenic activities but is not expected to eliminate them altogether because this would imply elimination of their inflicter as such.

Reformulating the calculation of mining privileges for medium and large mining

Directory of Open Access Journals (Sweden)

Pedro Franco Concha

2016-01-01

Full Text Available Throughout this paper those technical and accounting concepts of the Law of mining privileges that generate ambiguity and incongruity for businesses has been analyzed and identified. For this reason, we have developed a proposal amending the calculation of mining privileges based on two main aspects: (i terminology used in the law and (ii establishment of income before retribution to stakholders and taxes as a basis for calculating privileges. As a result, it was established as an object of study for all mining companies paying privileges; however, for purposes of the investigation three representative mining companies of medium and large mining were selected. Later interviews were arranged with financial and tax managers of the companies mentioned above as well as experts in the field of mining privileges; it was concluded that the concepts of "cost" and "corresponding fiscal year" mentioned in the Law generated ambiguities, inconsistencies and accounting distortions. Also, mining companies and experts agreed that the current basis for the calculation of the privileges is not adequate for the mining sector since it does not reflect the financial situation of companies. Therefore, a proposal for reformulation of the applied priviously and a new basis for calculating the mining privileges based on the cost of sales is made; since, in the cost of sales is found what Kieso and Weygandt (1999 denominated as "the price paid for the right to seek and find a hidden Natural resources, or paid by a source already discovered"

2017-01-01

New product development in real estate industry is a challenging process since it is related to long term concept and high cost. A newly proposed product development should meet customer need and their preferences which appropriate with customer buying power and company value. This research use data mining for profiling customer transaction and Analytic Hierarchy Process (AHP) method for product selection in new product development. This research utilizes Weka as data mining open source software to profiling data customers. The analysis correlated product preferences and profiling demography such as city, age, gender and occupation. Demography profiles gives description buying power and product preferences. The products proposed are based on customer profiles and rank of the product by AHP method. The product with the highest score will be proposed as new product development. Case studies of this research are real estate projects in Serang, Makassar, and Balikpapan. Makassar and Balikpapan are the project that already gained success and Serang is new project which new products development will be proposed to launch. Based on profiling and product preference of customer in Balikpapan, Makassar, and prospectus of Serang markets, new products development that will be proposed are house type of 120/200 m2 with price around Rp1.300.000.000 and house type of 71/120 m2 with price around Rp800.000.000. The markets of Serang and Balikpapan have similarities in profiles as urban city so the new products development will adopt the succeed story of Balikpapan project.

Use of Data Mining Techniques to Detect Medical Fraud in Health Insurance

2012-04-01

Full Text Available The health insurance claims application case the inspection usually relies on experts’ experience for verification and experienced personnel in charge for checking. However, due to the heavy work load and the insufficiency of manpower and experience, the ratio of miscarriages of justice is high, leading to improper settlement of claims and the waste of social resources. This paper takes advantage of data-mining technology to design models and find out cases requiring for manual inspection so as to save time and manpower. Six models are designed in this paper. By the analysis of the 20/80 principle and the coverage and accuracy ratio, a great number of periodic data (over 2 million records are fed back to the data-mining models after repetitive verification. Also, it is discovered that to integrate the data-mining technology and feed back to different business stages so as to establish early warning system will be an important topic for the health insurance system in hospital’s EMR in the future. Meanwhile, as the information acquired by data-mining needs to be stored and the traditional database technology has limitations. Next time, this paper explores the ontology framework to be set up by semantic network technology in the future in order to assist the storage of knowledge gained by data-mining.

Score Mining Rents in Terms of Investment Attractiveness of Peat Mining

Science.gov (United States)

Alexandrov, Gennady; Yablonev, Alexander

2017-11-01

In this article, as determinants in the system factors underlying the investment attractiveness of the peat industry is considered a rental factor, which predetermines the significant differences and peculiarities of the investment climate in the mining business and, in particular, in the sphere of peat mining. In contrast to modern studies treated the essence and role of rents in the economic mechanism, is proposed for a new approach to solving the problems of its formation. Our approach differs in that it, firstly, adequate rental relations, objectively in extractive industries, secondly, provides consensus in the interests of the owner of peat deposits and entrepreneurs, businesses in these deposits and, thus, thirdly, contributes to the creation of a favourable investment climate in the peat extraction industry. In practical terms, in accordance with the proposed approach, we have proposed specific allocation algorithm of mining rents from the profits of peat extraction enterprises.

Safety and welfare of Australian black coal mine employees

Energy Technology Data Exchange (ETDEWEB)

Azia, N.I.; Cram, K. [University of Wollongong, Wollongong, NSW (Australia). Faculty of Engineering

2001-07-01

The paper outlines the status of Australian coal mining industry with respect to safety and welfare of the mine employee. The impact of the longer shift hours and compressed working week are discussed in relation to workers safety and employment levels. Longer shift hours and compressed works have been shown to be a benefit to miners, both in safety and socially. The paper also examines the role of each of government organisations, the mining and manufacturing industries on the issue and goes on to describe the various environmental control measures introduced to the Australian coal mines to ensure that high safety standards are maintained. Dust monitoring and control, noise pollution control, and diesel particulate control measures have been targeted vigorously and as a result there has been a continued drop in the coal mine related diseases as well as a decline in the workers lost time injury claims. 11 refs., 7 figs., 6 tabs.

Between Critical and Uncritical Understandings: A Case Study Analyzing the Claims of Islamophobia Made in the Context of the Proposed ‘Super-Mosque’ in Dudley, England

Directory of Open Access Journals (Sweden)

Chris Allen

2013-04-01

Full Text Available Research highlights how usage and claims of Islamophobia tend to be simplistic and without nuance. Using a case study approach, this article considers the claims of Islamophobia made in relation to the proposed Dudley ‘super-mosque’. Setting out a narrative of the ‘super-mosque’, this article draws upon primary and secondary research to consider the claims and discourses of the major actors in the Dudley setting: the Dudley Muslim Association, Dudley Metropolitan Borough Council, the far-right especially the British National Party and the English Defence League, as well as individual political figures. Considering each in detail, this article seeks to evaluate the extent to which each of the actors and the claims of Islamophobia made against them might be valid. As well as exploring claims of Islamophobia within a ‘real’ environment, this article seeks to critically engage the opposition shown towards the mosque, the way in which the opposition campaigns were mobilized and engineered, and how the ideological meanings of Islamophobia was able to be readily utilized to validate and justify such opposition. In doing so, this article concludes that the claims and usage of Islamophobia was weak and that a more critical and nuanced usage of the term is urgently required.

Solution mining process

International Nuclear Information System (INIS)

Showalter, W.E.

1984-01-01

A solution mining process which may be used for uranium, thorium, vanadium, copper, nickel, molybdenum, rhenium, and selenium is claimed. During a first injection-and-production phase of between 6 months and 5 years, a leaching solution is injected through at least one well into the formation to solubilize the mineral values and form a pregnant liquor. This liquor is recovered through another well. The leaching solution contains sulfuric acid, nitric acid, hydrochloric acid, carbonic acid, an alkali metal carbonate, an alkali metal bicarbonate, ammonium carbonate or ammonium bicarbonate. Subsequently during a first production-only phase of between about 2 weeks and one year, injection of the leaching solution is suspended but pregnant liquor is still recovered. This stage is followed by a second injection-and-production phase of between 6 months and 5 years and a second production-only phase. The mineral values are separated from the pregnant liquor to form a barren liquor. The leaching agent is introduced into this liquor, and the solution is recycled. In a second claim for the solution mining of uranium, dilute carbonic acid is used as the leaching solution. The solution has a pH less than 7 and a bicarbonate ion concentration between about 380 ppm and 1000 ppm. The injection-and-production phase lasts between one and two years and the production only phase takes between one and four months. Carbon dioxide is introduced into the barren liquor to form a dilute carbonic acid solution and the solution is recycled

2013-09-01

To explore classification rules based on data mining methodologies which are to be used in defining strata in stratified sampling of healthcare providers with improved sampling efficiency. We performed k-means clustering to group providers with similar characteristics, then, constructed decision trees on cluster labels to generate stratification rules. We assessed the variance explained by the stratification proposed in this study and by conventional stratification to evaluate the performance of the sampling design. We constructed a study database from health insurance claims data and providers' profile data made available to this study by the Health Insurance Review and Assessment Service of South Korea, and population data from Statistics Korea. From our database, we used the data for single specialty clinics or hospitals in two specialties, general surgery and ophthalmology, for the year 2011 in this study. Data mining resulted in five strata in general surgery with two stratification variables, the number of inpatients per specialist and population density of provider location, and five strata in ophthalmology with two stratification variables, the number of inpatients per specialist and number of beds. The percentages of variance in annual changes in the productivity of specialists explained by the stratification in general surgery and ophthalmology were 22% and 8%, respectively, whereas conventional stratification by the type of provider location and number of beds explained 2% and 0.2% of variance, respectively. This study demonstrated that data mining methods can be used in designing efficient stratified sampling with variables readily available to the insurer and government; it offers an alternative to the existing stratification method that is widely used in healthcare provider surveys in South Korea.

High utility-itemset mining and privacy-preserving utility mining

Directory of Open Access Journals (Sweden)

Jerry Chun-Wei Lin

2016-03-01

Full Text Available In recent decades, high-utility itemset mining (HUIM has emerging a critical research topic since the quantity and profit factors are both concerned to mine the high-utility itemsets (HUIs. Generally, data mining is commonly used to discover interesting and useful knowledge from massive data. It may, however, lead to privacy threats if private or secure information (e.g., HUIs are published in the public place or misused. In this paper, we focus on the issues of HUIM and privacy-preserving utility mining (PPUM, and present two evolutionary algorithms to respectively mine HUIs and hide the sensitive high-utility itemsets in PPUM. Extensive experiments showed that the two proposed models for the applications of HUIM and PPUM can not only generate the high quality profitable itemsets according to the user-specified minimum utility threshold, but also enable the capability of privacy preserving for private or secure information (e.g., HUIs in real-word applications.

The closure of surface brown coal mines is a complex process with many specific considerations. In the Czech Republic a special project was proposed to analyze the types of environmental disturbance generated by surface mining operations and suggest procedures for the affected areas. It also aims to propose rehabilitation techniques for residual pits, considering their future use for recreational or development purposes. A Chabarovice mine case study demonstrates how to solve the problem of water flooding and utilization of the future residual lake. 2 figs

Background gamma radiation monitoring of three clusters of villages surrounding Mohuldih, Banduhurang and Bagjata villages, the proposed uranium mining areas in Singhbhum, Jharkhand

2008-01-01

Generation of power is a fundamental catalyst to the social and economic development of a country. India needs more power in order to have a strong industrial base and for infrastructure development. With this in view, there has been an emphasis on nuclear power as an alternative source in the field of electricity generation as the nuclear power can be an effective tool in reducing stress on the environment. The Singhbhum district in the state of Jharkhand in India has been known to have deposits of uranium and uranium mines like Jaduguda, Narwapahar, Bhatin etc have been operating in the region. With the increased requirement of electricity and hence suitable fuel, few more sites are proposed to mine uranium in the region. The sites proposed are near the villages of Mohuldih, Banduhurang and Bagjata and are proposed to be open cast mines. These areas of Singhbhum are not economically advanced areas. By and large, the population is poor and there are existing problems like malnutrition and poor health. The activities of mining and the associated developments in the region are expected to improve the economic condition of the residents either through direct employment in the mining facilities, or by indirect gains due to infrastructural developments in the region. In order to assess the impact of the mining operations on the environment and the population as well, it is necessary that the pre-operational survey be carried out in the regions in question. As is the practice, a complete pre-operational survey of the physical, chemical and environmental parameters has been carried out in the region. Background gamma radiation survey was also carried out, using the thermo luminescent dosimetry technique, to obtain the preoperational levels prevalent in the regions. This paper gives the results of the baseline background gamma radiation survey in the region. It was observed that the general gamma background levels of the areas, as measured using TLDs, was 1.36 ± 0.41 m

Rashmi, R. V.; Devalal, Shilpa; Jacob, Anjali; Vidhyapathi, C. M.

2017-11-01

Today’s world witnesses increased number of mine accidents caused due to explosion and fire. When the methane gas concentration goes high, it causes fire leading to explosion. In this paper, an IoT based system is proposed to ensure safety to the mine workers in underground collieries. The proposed system consists of DHT-11 sensor to monitor the temperature and humidity of coal mines. When the gas sensor detects high methane gas level, blower is activated so that the atmospheric air can be pumped in from outside to dilute the gas concentration. The smoke sensor is also used to detect the fire. In case of any abnormality in any of these parameters the buzzer sounds. All these parameters are uploaded to the cloud directly so that the people at the control station can be well informed of the underground mines.

The draft Environmental Impact Statement (ESI) for the proposed uranium mines at Jabiluka, about 20 Km north of the existing Ranger mine in the Northern Territory was released on 17 October 1996. The EIS concluded that any impact of the proposed mine will be localised, small-scale and temporary. Jabiluka will contribute some $3.8 billion to national economic welfare over the project's predicted 28-year life

Mining Contratação License in the New Regulatory Framework of Brazilian Mining: Some Notes on the Institutes of Research Authorization and Mining Concession

Directory of Open Access Journals (Sweden)

Adhemar Ronquim Filho

2013-06-01

Full Text Available Given the importance of mining nowadays, Government seeks ways to stimulate its growth, focusing on potentializing research and the advancement of mineral processing, the basic items for speeding up this activity in a profitable way. In this sense, the discussions on the crystallization of a new regulatory framework for the Brazilian mining have been deepened and, despite gathering a significant number of proposals, it does not have a closed text, and, currently, it is far from obtaining an approval or a final word (despite the urgency. However, the analysis of the proposals that have been presented reveals that there is an intention to institute new rules for the modernization of Brazilian mining, and this paper has the purpose of suggesting ways to reconcile conflicts permeated by various dissonant interests that surround the Brazilian mining at this time. It should be emphasized that, given the lack of official disclosure of the amendments proposed, the approach will continue limited to what has been released by MME (Ministry of Mines and Energy and by the studies that have already been presented by experts in the field (connected to government and/or private businesses. It is restricted to discuss changes to be implemented with the new regulatory framework, highlighting points to be observed, and, among the topics that require mandatory update, we can emphasize the changes in the procedures of exploration permits and mining.

Tensile strength and the mining of black holes.

Science.gov (United States)

Brown, Adam R

2013-11-22

There are a number of important thought experiments that involve raising and lowering boxes full of radiation in the vicinity of black hole horizons. This Letter looks at the limitations placed on these thought experiments by the null energy condition, which imposes a fundamental bound on the tensile-strength-to-weight ratio of the materials involved, makes it impossible to build a box near the horizon that is wider than a single wavelength of the Hawking quanta, and puts a severe constraint on the operation of "space elevators" near black holes. In particular, it is shown that proposals for mining black holes by lowering boxes near the horizon, collecting some Hawking radiation, and dragging it out to infinity cannot proceed nearly as rapidly as has previously been claimed. As a consequence of this limitation, the boxes and all the moving parts are superfluous and black holes can be destroyed equally rapidly by threading the horizon with strings.

Medico-legal claims against English radiologists: 1995-2006.

Science.gov (United States)

Halpin, S F S

2009-12-01

A list of claims against radiologists from 1995-2006 was obtained from the NHS Litigation Authority. It shows a total of 440 claims. The largest number of claims (199) related to delayed or missed diagnoses of cancer, and 73 claims related to breast radiology. There is a trend for a mild increase in the number of claims each year. 30 claims were made after a false-positive diagnosis of cancer. Just under pound8.5 million has so far been paid in damages, with a further pound5 million in legal fees. A claim for multiple missed diagnoses of breast cancer led to a pay-out of pound464 000 ( pound673 000 after legal fees); the largest sum awarded following a delay in the diagnosis of an individual cancer was pound300 000. The subtle legal distinction between error and negligence is reviewed here. The reason why breast radiologists are more likely to be sued than any other type of British radiologist is also discussed, along with the implications for UK radiological practice, particularly in light of the recent Chief Medical Officer's report on revalidation. A method is proposed that may protect radiologists from allegations of clinical negligence in the future.

International Nuclear Information System (INIS)

1978-01-01

The draft concerns the proposed issuance of approvals, permits, and licenses to the Homestake Mining Company for the implementation of the Pitch Project. The Pitch Project consists of mining and milling operations involving uranium ore deposits located in Gunnison National Forest, Saguache County, Colorado. Mining of uranium ore will take place over an estimated period of 20 years; a mill with a nominal capacity of 544 metric tons per day (600 tons per day) will be constructed and operated as long as ore is available. The waste material (tailings) from the mill, also produced at a rate of about 544 metric tons per day (600 tons per day), will be buried onsite at the head end of a natural valley. The environmental impacts are summarized in sections on the existing environment, applicant's proposed mining and milling operation, environmental effects of accidents, monitoring programs, productivity, commitment of resources, alternatives, and cost-benefit evaluation

A Data Mining Classification Approach for Behavioral Malware Detection

Directory of Open Access Journals (Sweden)

Monire Norouzi

2016-01-01

Full Text Available Data mining techniques have numerous applications in malware detection. Classification method is one of the most popular data mining techniques. In this paper we present a data mining classification approach to detect malware behavior. We proposed different classification methods in order to detect malware based on the feature and behavior of each malware. A dynamic analysis method has been presented for identifying the malware features. A suggested program has been presented for converting a malware behavior executive history XML file to a suitable WEKA tool input. To illustrate the performance efficiency as well as training data and test, we apply the proposed approaches to a real case study data set using WEKA tool. The evaluation results demonstrated the availability of the proposed data mining approach. Also our proposed data mining approach is more efficient for detecting malware and behavioral classification of malware can be useful to detect malware in a behavioral antivirus.

Aboriginal Determination: Native Title Claims and Barriers to Recognition

Directory of Open Access Journals (Sweden)

Zia Akhtar

2011-09-01

Full Text Available The Australian government has proposed a referendum in 2012 to decide the constitutional status of its indigenous people. There is at present no mechanism to define the indigenous people as a domestic or foreign entity of the Commonwealth. This is an important issue because other settler governments have developed a framework to implement their relationship with the native people. As a result, it is difficult prove title to land that has been abrogated by the deeds of the settlers. In Mabo v Queensland (2,the Commonwealth government was found to have breached its fiduciary duty to the Aboriginal peoples. The judgment led to the Native Title Act 1993 that established the process of asserting native rights that were held to coexist with pastoral ownership. The promulgation of the Native Title Amendment Act 1998 reversed this process and augmented the powers of non-native landlords by providing the device to extinguish native rights. In Western Australia v Ward, a mining lease was held to have precedence over native title that was adjudged to be part of a bundle of rights. In implementing the Native Title Act the issue turns on the determination of the ties to land/ sea that the government allows to the Aboriginal peoples. The judgment in Harrington-Smith on behalf of the Wongatha People v Western Australia indicates that title can be excluded on procedural grounds and that there was an incompatibility between the claims of the Aboriginal peoples and the settlers’ claims. The road map towards a more effective regime of proving title can be achieved if the Aboriginal peoples are granted recognition as a nation in the Constitution and a treaty is signed with them.

Mining lore : Chinese labourers in BC's coal mines

Energy Technology Data Exchange (ETDEWEB)

Baldwin, C.

2010-09-15

This article presented a historical review of Chinese labourers in Canada's industries and how they were often exploited and treated poorly. The 1860 gold rush in British Columbia attracted the first labourers from China. More labourers followed, the majority male, to work in the coal mines around Nanaimo. More than half the employees at coal baron Robert Dunsmuir's Wellington mine on Vancouver Island were Chinese labourers who worked under conditions and wages that other miners would not accept. During a large strike at the Wellington Mine in 1883, the striking white miners were replaced with Chinese from Victoria, which contributed to a brewing anti-Chinese sentiment. The striking miners eventually withdrew their demand for higher wages, insisting only that Dunsmuir rid his mine of the Chinese. Dunsmuir refused, held out, and broke the strike. When an anti-immigration bill was passed in 1884 by the British Columbia (BC) Legislative Assembly, the Canadian government stepped in, only to hire thousands of Chinese labourers to work on the railway. Their low wages saved contractors $3 million, making construction economically feasible. However, just a few weeks after blocking BC's anti-immigration bill, the Canadian government passed a Chinese Immigration Act that would come into effect only after construction was completed. The Act restricted and regulated Chinese immigration, and imposed a head tax on any Chinese entering the country, making it unaffordable to bring a wife and family to Canada. When the railroad was completed, thousands of Chinese labourers were left unemployed with nowhere to go. In 1887, an explosion at a Nanaimo mine killed 150 employees. The miners blamed the Chinese, claiming that their lack of English made them a safety hazard. By the early 1920s, the Chinese community in Victoria formed the Chinese Benevolent Association to provide general welfare assistance and oppose discriminatory laws. In 2006, the Canadian government

A novel method for estimating methane emissions from underground coal mines: The Yanma coal mine, China

Science.gov (United States)

Ji, Zhong-Min; Chen, Zhi-Jian; Pan, Jie-Nan; Niu, Qing-He

2017-12-01

As the world's largest coal producer and consumer, China accounts for a relatively high proportion of methane emissions from coal mines. Several estimation methods had been established for the coal mine methane (CMM) emission. However, with large regional differences, various reservoir formation types of coalbed methane (CBM) and due to the complicated geological conditions in China, these methods may be deficient or unsuitable for all the mining areas (e.g. Jiaozuo mining area). By combing the CMM emission characteristics and considering the actual situation of methane emissions from underground coal mine, we found that the methane pre-drainage is a crucial reason creating inaccurate evaluating results for most estimation methods. What makes it so essential is the extensive pre-drainage quantity and its irrelevance with annual coal production. Accordingly, the methane releases were divided into two categories: methane pre-drainage and methane release during mining. On this basis, a pioneering method for estimating CMM emissions was proposed. Taking the Yanma coal mine in the Jiaozuo mining area as a study case, the evaluation method of the pre-drainage methane quantity was established after the correlation analysis between the pre-drainage rate and time. Thereafter, the mining activity influence factor (MAIF) was first introduced to reflect the methane release from the coal and rock seams around where affected by mining activity, and the buried depth was adopted as the predictor of the estimation for future methane emissions. It was verified in the six coal mines of Jiaozuo coalfield (2011) that the new estimation method has the minimum errors of 12.11%, 9.23%, 5.77%, -5.20%, -8.75% and 4.92% respectively comparing with other methods. This paper gives a further insight and proposes a more accurate evaluation method for the CMM emissions, especially for the coal seams with low permeability and strong tectonic deformation in methane outburst coal mines.

Defining hip fracture with claims data: outpatient and provider claims matter.

Science.gov (United States)

Berry, S D; Zullo, A R; McConeghy, K; Lee, Y; Daiello, L; Kiel, D P

2017-07-01

Medicare claims are commonly used to identify hip fractures, but there is no universally accepted definition. We found that a definition using inpatient claims identified fewer fractures than a definition including outpatient and provider claims. Few additional fractures were identified by including inconsistent diagnostic and procedural codes at contiguous sites. Medicare claims data is commonly used in research studies to identify hip fractures, but there is no universally accepted definition of fracture. Our purpose was to describe potential misclassification when hip fractures are defined using Medicare Part A (inpatient) claims without considering Part B (outpatient and provider) claims and when inconsistent diagnostic and procedural codes occur at contiguous fracture sites (e.g., femoral shaft or pelvic). Participants included all long-stay nursing home residents enrolled in Medicare Parts A and B fee-for-service between 1/1/2008 and 12/31/2009 with follow-up through 12/31/2011. We compared the number of hip fractures identified using only Part A claims to (1) Part A plus Part B claims and (2) Part A and Part B claims plus discordant codes at contiguous fracture sites. Among 1,257,279 long-stay residents, 40,932 (3.2%) met the definition of hip fracture using Part A claims, and 41,687 residents (3.3%) met the definition using Part B claims. 4566 hip fractures identified using Part B claims would not have been captured using Part A claims. An additional 227 hip fractures were identified after considering contiguous fracture sites. When ascertaining hip fractures, a definition using outpatient and provider claims identified 11% more fractures than a definition with only inpatient claims. Future studies should publish their definition of fracture and specify if diagnostic codes from contiguous fracture sites were used.

Underground Mining Method Selection Using WPM and PROMETHEE

Science.gov (United States)

Balusa, Bhanu Chander; Singam, Jayanthu

2018-04-01

The aim of this paper is to represent the solution to the problem of selecting suitable underground mining method for the mining industry. It is achieved by using two multi-attribute decision making techniques. These two techniques are weighted product method (WPM) and preference ranking organization method for enrichment evaluation (PROMETHEE). In this paper, analytic hierarchy process is used for weight's calculation of the attributes (i.e. parameters which are used in this paper). Mining method selection depends on physical parameters, mechanical parameters, economical parameters and technical parameters. WPM and PROMETHEE techniques have the ability to consider the relationship between the parameters and mining methods. The proposed techniques give higher accuracy and faster computation capability when compared with other decision making techniques. The proposed techniques are presented to determine the effective mining method for bauxite mine. The results of these techniques are compared with methods used in the earlier research works. The results show, conventional cut and fill method is the most suitable mining method.

Personal continuous route pattern mining

Institute of Scientific and Technical Information of China (English)

Qian YE; Ling CHEN; Gen-cai CHEN

2009-01-01

In the daily life, people often repeat regular routes in certain periods. In this paper, a mining system is developed to find the continuous route patterns of personal past trips. In order to count the diversity of personal moving status, the mining system employs the adaptive GPS data recording and five data filters to guarantee the clean trips data. The mining system uses a client/server architecture to protect personal privacy and to reduce the computational load. The server conducts the main mining procedure but with insufficient information to recover real personal routes. In order to improve the scalability of sequential pattern mining, a novel pattern mining algorithm, continuous route pattern mining (CRPM), is proposed. This algorithm can tolerate the different disturbances in real routes and extract the frequent patterns. Experimental results based on nine persons' trips show that CRPM can extract more than two times longer route patterns than the traditional route pattern mining algorithms.

Sex work and the claim for grassroots legislation.

Science.gov (United States)

Fassi, Marisa N

2015-01-01

The aim of this paper is to contribute to understanding of legal models that aim to control sex work, and the policy implications of these, by discussing the experience of developing a grassroots legislation bill proposal by organised sex workers in Córdoba, Argentina. The term 'grassroots legislation' here refers to a legal response that derives from the active involvement of local social movements and thus incorporates the experiential knowledge and claims of these particular social groupings in the proposal. The experience described in this paper excludes approaches that render sex workers as passive victims or as deviant perpetrators; instead, it conceives of sex workers in terms of their political subjectivity and of political subjectivity in its capacity to speak, to decide, to act and to propose. This means challenging current patterns of knowledge/power that give superiority to 'expert knowledge' above and beyond the claims, experiences, knowledge and needs of sex workers themselves as meaningful sources for law making.

A Systematic Method to Analyze Force Majeure in Construction Claims

Directory of Open Access Journals (Sweden)

Saud Alshammari

2017-12-01

Full Text Available In construction delay claims, force majeure is normally recognized as an excusable risk that entitles contractors only to time extensions, but neither of the contracting parties is entitled to monetary compensation to recover delay damages. However, there are instances where contractors are entitled to both time and cost compensations, as evidenced by some court cases relating to force majeure claims. Such instances involve attributing the occurrence of the force majeure to the effect of other prior delay events that pushed project performance into the period of the force majeure. Existing delay analysis methods are not capable of addressing this issue, as none take the impact of other delays into consideration when analyzing force majeure claims. Stimulated by this gap, this study proposes an improved and sound method for fairly analyzing the responsibility of force majeure delay claims amongst contracting parties. This method was implemented on a case project to help demonstrate its application and also ascertain its practicability. The contribution of this paper is twofold. First, it has highlighted the situation of force majeure delay that can be compensable, creating more awareness among researchers and industry practitioners. The second is a proposed systematic process to appropriately analyze its responsibility, which equitably addresses claims from such delays with little or no chance of dispute ensuing.

Recent developments in Australia's uranium mining industry

International Nuclear Information System (INIS)

McKay, A.D.

2001-01-01

Uranium is produced at two mining/milling operations in Australia - Ranger in the Alligator Rivers Region of the Northern Territory, and Olympic Dam in South Australia. In 1996, Ranger produced 4138 tonnes (t) U 3 O 8 from stockpiled ore mined from Ranger No. 1 Orebody. The capacity of the Ranger mill is being expanded to 5000 tonnes per annum (tpa) U 3 O 8 to coincide with the commencement of mining from No. 3 Orebody in mid-1997. The Olympic Dam copper-uranium-gold-silver deposit is the world's largest deposit of low cost uranium. The operation currently has an annual production of 85,000 t copper, 1700 t U 3 O 8 and associated gold and silver. WMC Ltd proposes to expand annual production to 200 000 t copper and approximately 4600 t U 3 O 8 by end of 1999. The environmental impact of the expansion is being assessed jointly by both Commonwealth and South Australian Governments. A draft Environmental Impact Statement (EIS) was released in May. Since its election in March 1996, the Liberal/National Party Coalition Government has made a number of changes to the Commonwealth Government's policies relating to uranium mining, including removal of the former Government's 'three mines' policy, and relaxation of the guidelines for foreign investment in Australian uranium mines. These changes, together with an improved outlook for the uranium market, have resulted in proposals to develop new mines at Jabiluka (Northern Territory), Kintyre (Western Australia) and Beverley (South Australia). Energy Resources of Australia Ltd proposes to develop an underground mine at Jabiluka with the ore to be processed at Ranger mill. Initial production will be 1800 tpa U 3 O 8 which will increase to 4000 tpa U 3 O 8 by the 14th year. The draft EIS was released for public comment in October 1996, and the final EIS is to be released in June 1997. Canning Resources Ltd proposes to mine the Kintyre deposit by open cut methods commencing in 1999 with an annual production of 1200 tpa U 3 O 8

Oil sands mining and reclamation cause massive loss of peatland and stored carbon

Science.gov (United States)

Rooney, Rebecca C.; Bayley, Suzanne E.; Schindler, David W.

2012-01-01

We quantified the wholesale transformation of the boreal landscape by open-pit oil sands mining in Alberta, Canada to evaluate its effect on carbon storage and sequestration. Contrary to claims made in the media, peatland destroyed by open-pit mining will not be restored. Current plans dictate its replacement with upland forest and tailings storage lakes, amounting to the destruction of over 29,500 ha of peatland habitat. Landscape changes caused by currently approved mines will release between 11.4 and 47.3 million metric tons of stored carbon and will reduce carbon sequestration potential by 5,734–7,241 metric tons C/y. These losses have not previously been quantified, and should be included with the already high estimates of carbon emissions from oil sands mining and bitumen upgrading. A fair evaluation of the costs and benefits of oil sands mining requires a rigorous assessment of impacts on natural capital and ecosystem services. PMID:22411786

All the requests for authorisation to bear health claims under Articles 13(5) and 14 in the context of appetite ratings and weight management have received a negative opinion by the European Food Safety Authority (EFSA), mainly because of the insufficient substantiation of the claimed effects (CEs). This manuscript results from an investigation aimed to collect, collate and critically analyse the information related to outcome variables (OVs) and methods of measurement (MMs) in the context of appetite ratings and weight management compliant with Regulation 1924/2006. Based on the literature review, the appropriateness of OVs and MMs was evaluated for specific CEs. This work might help EFSA in the development of updated guidance addressed to stakeholders interested in bearing health claims in the area of weight management. Moreover, it could drive the applicants during the design of randomised controlled trials aimed to substantiate such claims.

Effects of natural conditions on development of a landslide at a mining area

Energy Technology Data Exchange (ETDEWEB)

Palki, J

1982-01-01

Investigations show that 39.4% of landslides at the mining ground in the Rybnik coal region is caused by factors other than underground mining. Determining the actual cause of a landslide is of importance for an underground mine because, as a rule, all ground damage is claimed to be caused by underground mining. A case of a landslide in the Rybnik area is analyzed. Landslide development is shown in a photo and 17 schemes. Ground morphology, water conditions and effects of underground longwall mining are evaluated. The analyses show that ground subsidence caused by underground mining ranging from 2.0 m to 3.1 m reduced the angle of slope inclination preventing more intensive landslides. Intensity of horizontal deformation was too low to cause a landslide. Slope stability decrease was caused by loose rock layers (sands) at the base of a hill. Accumulation of atmospheric precipitation and disturbed water outflow caused an increase in the plasticity of the sand. Mechanical vibrations caused by train traffic on tracks located close to the slope were an additional factor causing landslide development. (6 refs.)

Prairie of mine(s) : cultural reclamation of the Estevan/Bienfait Coalfields

Energy Technology Data Exchange (ETDEWEB)

Baxter, S.

2010-07-01

A cultural reclamation project was launched in the Bienfait region of southern Saskatchewan where lignite mining has been ongoing since the 1800s. Evidence of 5 surface mines, 2 power stations and thousands of acres of spoil piles remain at the abandoned site. The region also comprises 140 abandoned underground mines and 4 mined-out townsites. The project introduced cultural reclamation into the role of landscape architecture, specifically in the planning and design of reclaimed mining lands. At the present time, the reclamation of post-extractive sites is limited to focusing almost exclusively on ecological factors, but failing to recognize the people and the industrial processes that actively transformed the landscape can disengage people from their past. The project concludes with a proposed master plan in addition to a few site-specific interventions that interrogate and explore the role of experiential, cultural, and historical elements in the reclamation of a site. In doing so, awareness is created about the ways in which various landscapes are manipulated every day in order for people to live in greater comfort.

Overview of the environmental impact assessment for the proposed expansion of the Elliot Lake Ontario uranium mines

International Nuclear Information System (INIS)

Gorber, D.M.; Graham, R.G.; Ibbotson, B.G.

1978-01-01

As a result of the resurgence in the demand for uranium, Denison Mines Limited and Rio Algom Limited began preparations, in 1973 and 1974 respectively, for expansion of their facilities at Elliot Lake, Ontario. These programmes involved not only the expansion of facilities currently in operation in the area, but also the rehabilitation of non-operating properties that were previously used during the 1960's. This paper reviews the methodology employed during the environmental assessment study of the proposed expansion and highlights the long and short-term strategies recommended

Water pollution - control of pollution regulations: water pollution from abandoned mines; pre-notification of mine abandonment consultation paper and draft regulations

Energy Technology Data Exchange (ETDEWEB)

NONE

1997-02-01

The paper contains proposals to specify the content of the pre-abandonment notices which UK mine operators will be required to give in the future. The proposals are designed to enhance the Environment Agency`s ability to tackle water pollution from abandoned mines. They set out the precise contents of the notification, which mine operators will have to send to the Agency at least six months in advance of any intended abandonment. The regulations will cover coal and non-coal mines. Estimated compliance costs to business have been drawn up following consultation with the Department of Trade and Industry, the Health and Safety Executive, the Coal Authority and the Environment Agency. The regulations are due in late spring 1998.

A Proposed Data Fusion Architecture for Micro-Zone Analysis and Data Mining

Energy Technology Data Exchange (ETDEWEB)

Kevin McCarthy; Milos Manic

2012-08-01

Data Fusion requires the ability to combine or “fuse” date from multiple data sources. Time Series Analysis is a data mining technique used to predict future values from a data set based upon past values. Unlike other data mining techniques, however, Time Series places special emphasis on periodicity and how seasonal and other time-based factors tend to affect trends over time. One of the difficulties encountered in developing generic time series techniques is the wide variability of the data sets available for analysis. This presents challenges all the way from the data gathering stage to results presentation. This paper presents an architecture designed and used to facilitate the collection of disparate data sets well suited to Time Series analysis as well as other predictive data mining techniques. Results show this architecture provides a flexible, dynamic framework for the capture and storage of a myriad of dissimilar data sets and can serve as a foundation from which to build a complete data fusion architecture.

Method of solution mining subsurface orebodies to reduce restoration activities

Energy Technology Data Exchange (ETDEWEB)

Hartman, G.J.

1984-01-24

A method of solution mining is claimed wherein a lixiviant containing both leaching and oxidizing agents is injected into the subsurface orebody. The composition of the lixiviant is changed by reducing the level of oxidizing agent to zero so that soluble species continue to be removed from the subsurface environment. This reduces the uranium level of the ground water aquifer after termination of the lixiviant injection.

Open-pit coal mine production sequencing incorporating grade blending and stockpiling options: An application from an Indian mine

Science.gov (United States)

Kumar, Ashish; Chatterjee, Snehamoy

2017-05-01

Production scheduling is a crucial aspect of the mining industry. An optimal and efficient production schedule can increase the profits manifold and reduce the amount of waste to be handled. Production scheduling for coal mines is necessary to maintain consistency in the quality and quantity parameters of coal supplied to power plants. Irregularity in the quality parameters of the coal can lead to heavy losses in coal-fired power plants. Moreover, the stockpiling of coal poses environmental and fire problems owing to low incubation periods. This article proposes a production scheduling formulation for open-pit coal mines including stockpiling and blending opportunities, which play a major role in maintaining the quality and quantity of supplied coal. The proposed formulation was applied to a large open-pit coal mine in India. This contribution provides an efficient production scheduling formulation for coal mines after utilizing the stockpile coal within the incubation periods with the maximization of discounted cash flows. At the same time, consistency is maintained in the quality and quantity of coal to power plants through blending and stockpiling options to ensure smooth functioning.

Process mining includes the automated discovery of processes from event logs. Based on observed events (e.g., activities being executed or messages being exchanged) a process model is constructed. One of the essential problems in process mining is that one cannot assume to have seen all possible...... behavior. At best, one has seen a representative subset. Therefore, classical synthesis techniques are not suitable as they aim at finding a model that is able to exactly reproduce the log. Existing process mining techniques try to avoid such “overfitting” by generalizing the model to allow for more...... support for it). None of the existing techniques enables the user to control the balance between “overfitting” and “underfitting”. To address this, we propose a two-step approach. First, using a configurable approach, a transition system is constructed. Then, using the “theory of regions”, the model...

In-situ leach mining: the next quantum leap?

International Nuclear Information System (INIS)

Hancock, S.

1988-01-01

The opportunities and problems which in-situ leach mining technology presents to the mining industry are considered. These are exemplified by concerns addressed in the development of a proposal to mine uranium by in-situ leach techniques at Beverley in South Australia. The technique proposed at Beverley will use sulphuric acid with hydrogen peroxide or dissolved oxygen as the lixivient. Pre-treatment of the aquifer will be necessary to remove excess calcium carbonate, and the system will employ a slightly overpumped output of fluid through the wellfield to reduce the risk of excursions of mining solutions. The input and output patterns will also be varied to take account of the hydrogeological conditions such as confining bed thickness and permeability. Much study has been directed towards the post mining condition of the ore zone and the threat it may pose to the water resources of the region. 10 refs., 1 fig

Medical malpractice is the primary method by which people who believe they have suffered an injury in the course of medical care seek compensation in the United States and Canada. An increasing body of research demonstrates that failure to correctly diagnose is the most common allegation made in malpractice claims against radiologists. Since the 1994 survey by the Society of Chairmen of Radiology in Children's Hospitals (SCORCH), no other published studies have specifically examined the frequency or clinical context of malpractice claims against pediatric radiologists or arising from pediatric imaging interpretation. We hypothesize that the frequency, character and outcome of malpractice claims made against pediatric radiologists differ from those seen in general radiology practice. We searched the Controlled Risk Insurance Co. (CRICO) Strategies' Comparative Benchmarking System (CBS), a private repository of approximately 350,000 open and closed medical malpractice claims in the United States, for claims related to pediatric radiology. We further queried these cases for the major allegation, the clinical environment in which the claim arose, the clinical severity of the alleged injury, indemnity paid (if payment was made), primary imaging modality involved (if applicable) and primary International Classification of Diseases, 9th revision (ICD-9) diagnosis underlying the claim. There were a total of 27,056 fully coded claims of medical malpractice in the CBS database in the 5-year period between Jan. 1, 2010, and Dec. 31, 2014. Of these, 1,472 cases (5.4%) involved patients younger than 18 years. Radiology was the primary service responsible for 71/1,472 (4.8%) pediatric cases. There were statistically significant differences in average payout for pediatric radiology claims ($314,671) compared to adult radiology claims ($174,033). The allegations were primarily diagnosis-related in 70% of pediatric radiology claims. The most common imaging modality

Smith, Peter M; Black, Oliver; Keegel, Tessa; Collie, Alex

2014-03-01

To examine if the factors associated with days of absence following a work-related injury are similar for mental health versus musculoskeletal (MSK) conditions. A secondary analysis of wage replacement workers' compensation claims in the state of Victoria, Australia. We examined the relationship between individual, injury, occupational and workplace variables with days of wage replacement over the 2-year period following first day of absence from work separately for mental health claims and MSK claims using negative binomial regression models. Mental health conditions were associated with a greater number of days of absence over the 2 years following first incapacity compared to MSK conditions. Differences were observed in employment, injury and industry variables on absence from work for mental claims compared to MSK claims. Working in the agriculture, forestry, fishing and mining industries and employment with a small organisation were more strongly associated with the number of days of wage-replacement among MSK compared to mental health claims, and working in the public administration and safety, or education and training industries or being employed in a position with high time pressure were associated with greater days of wage-replacement among mental health compared to MSK claims. Predictors of days away from work in the 2 years following an injury differ for mental health versus MSK claims. Given the increasing number of mental health claims in Australia more research is required to understand differences in return-to-work for this group of claimants compared to those with physical injuries.

Full Text Available The research is aimed at analyzing the ICSID (International Centre Settlement Investment Dispute decision in solving a dispute between Churchill Mining PLC and the Government of the Republic of Indonesia. The case brought to the public attention, because mining license owned by PT. Ridlatama which acquired from Churchill Mining PLC had been revocated. Churchill Mining PLC holds 75% share of PT. Ridlatama and it suffered losses caused by the revocation of its mining license. Churchill Mining PLC filed the case to the local court but it failed. Churchill Mining PLC then sought ruling from International arbitration or ICSID. On December 6, 2016, ICSID issued a decision that clearly threw out Churchill Mining PLC claim. ICSID, the World Bank court, ordered the firm to pay a total of US$.9.446.528 in cost to the Government of the Republic of Indonesia. It is based on the evidences that the UK-Australia company did the fraud and had document forgery of coal mining permit in East Kutai, Indonesia. So the firm has violated the Bilateral Investment Treaties between Indonesia-UK and Indonesia-Australia.

Seafloor massive sulfide deposits support unique megafaunal assemblages: Implications for seabed mining and conservation.

Science.gov (United States)

Boschen, Rachel E; Rowden, Ashley A; Clark, Malcolm R; Pallentin, Arne; Gardner, Jonathan P A

2016-04-01

Mining of seafloor massive sulfides (SMS) is imminent, but the ecology of assemblages at SMS deposits is poorly known. Proposed conservation strategies include protected areas to preserve biodiversity at risk from mining impacts. Determining site suitability requires biological characterisation of the mine site and protected area(s). Video survey of a proposed mine site and protected area off New Zealand revealed unique megafaunal assemblages at the mine site. Significant relationships were identified between assemblage structure and environmental conditions, including hydrothermal features. Unique assemblages occurred at both active and inactive chimneys and are particularly at risk from mining-related impacts. The occurrence of unique assemblages at the mine site suggests that the proposed protected area is insufficient alone and should instead form part of a network. These results provide support for including hydrothermally active and inactive features within networks of protected areas and emphasise the need for quantitative survey data of proposed sites.

Influence of Mining Thickness on the Rationality of Upward Mining in Coal Seam Group

Directory of Open Access Journals (Sweden)

Y. Li

2016-04-01

Full Text Available This study aimed to determine the influence of mining thickness on the rationality of upward mining in coal seam group. Numerical simulation and theoretical analysis were performed to investigate the influence of the mining thicknesses of initial mining seam on the destruction and pressure relief effect of the upper coal seam in a high-gas coal seam group. The mechanical model of the roof failure based on the mining thickness was established by assuming that the gob formed after adjacent panels have fully been caved is the infinite plane. On the basis of this model, an equation was derived to calculate the roof failure height of the panel. Considering the geological conditions of No. 9 and No. 12 coal seams of Zhaogezhuang Coal Mine, economic effectiveness, and proposed techniques, we concluded that the top layer (4 m of the No. 12 coal seam should be mined first. The top layer of the No. 9 coal seam should be subsequently mined. The topcaving technique was applied to the exploitation of the lower layer of the No. 12 coal seam. Practically monitored data revealed that the deformation and failure of the No. 2699 panel roadway was small and controllable, the amount of gas emission was reduced significantly, and the effect of upward mining was active. The results of this study provide theory basics for mine designing, and it is the provision of a reference for safe and efficient coal exploitation under similar conditions.

Measurement of quantitative species diversity on reclaimed coal mine lands: A brief overview of the Wyoming regulatory proposal

International Nuclear Information System (INIS)

Vincent, R.B.

1998-01-01

The Wyoming Land Quality Division (LQD) Coal Rules and Regulations require mine operators to specify quantitative procedures for evaluating postmining species diversity and composition. Currently, permit commitments range from deferring to commit to a quantitative procedure until some future date to applying various similarity/diversity indices for comparison of reclaimed lands to native vegetation communities. Therefore, the LQD began trying to develop a standardized procedure to evaluate species diversity and composition, while providing operator flexibility. Review of several technical publications on the use of similarity and diversity indices, and other measurement techniques indicate that a consensus has not been reached on which procedure is most appropriate for use on reclaimed mine lands. In addition, implementation of many of the recommended procedures are not practical with regards to staff and data limitations. As a result, the LQD has developed an interim procedure, based on site-specific baseline data, to evaluate postmining species diversity and composition success with respect to bond release requests. This paper reviews many of the recommended procedures, outlines some of the pros and cons, and provides a specific example of how the proposed interim procedure was applied to an actual coal mine permit. Implementation of this or a similar procedure would allow for site-specific standardization of permits and regulatory requirements, thus reducing review time and reducing some of the subjectivity surrounding a component of the Wyoming bond release requirements

Some may beg to differ: individual beliefs and group political claims.

Science.gov (United States)

Lipscomb, Martin

2013-10-01

While nurses can and do behave as intentional political agents, claims that nurses collectively do (empiric), should (normative) or must (regulatory) act to advance political objectives lack credibility. This paper challenges the coherence and legitimacy of political demands placed upon nurses. It is not suggested that nurses ought not to contribute to political discourse and activity. That would be foolish. However, the idea that nursing can own or exhibit a general political will is discarded. It is suggested that to protect and advance political discussion, to aid explanatory adequacy and clarity, the form in which nursing associates itself with political claims merits critical appraisal. Thus significant numbers of nurses probably reject or disagree with many of the political claims that attach to them--claims often made on their behalf. More specifically, the individual beliefs and goals of nurses can be in conflict with the political pronouncements of nursing scholars and organizations (group agents). It is proposed that nurses need not share substantive normative beliefs/goals and, if this proposal holds, group descriptors such as 'nurses' and 'nursing' cannot meaningfully or easily attach to political claims. Shared value theory is linked to the fallacy of composition and the concept of collective ascription error is introduced to explore the implausibility of using group descriptors such as 'nurses' and 'nursing' to refer to the beliefs/goals of all nurses. © 2013 John Wiley & Sons Ltd.

Final environmental impact statement. Marquez uranium mine

International Nuclear Information System (INIS)

1984-01-01

As one of many activities TVA has undertaken to ensure an adequate supply of uranium for these plants, TVA has proposed to underground mine, through its operator, the uranium deposits located in the Canon de Marquez in McKinley County, New Mexico. Construction and operation of the underground mine would be expected to have the following environmental effects: (a) a temporary change in land use for 48.5 hectares from wildlife habitat and recreation to mineral extraction; (b) a minor alteration in topography near the proposed pond sites due to reclamation of waste rock piles; (c) minimal impacts on land due to limited vehicular traffic and road construction; (d) temporary depression of ground water levels in the Westwater Canyon Member of the Morrison Formation in the mine vicinity during mine life; (e) short-term project-induced impacts to surface water and shallow ground water quality; (f) a temporary decrease in air quality in the vicinity of the mining operations due to fugitive dust and exhaust emissions from combustion-driven mining and support vehicles and releases of radon and short-lived radon progeny from ventilation shafts and ore piles; (g) a temporary decrease of plant and animal species at the mine site; (h) a minor and temporary effect on aquatic systems downstream from the mine and settling ponds due to sedimentation; and (i) a minor increase of noise levels in the immediate vicinity of mine shafts and vents. The no action alternative and alternatives for securing uranium ore by other methods were considered but were found insufficient to meet TVA objectives. None of the alternatives explored were environmentally preferable. TVA also evaluated site specific alternatives including the following: different shaft and support building siting, mining techniques, and reclamation options. 25 figures, 20 tables

Radiation safety needs for the resurgent uranium mining industry

Waggitt, Peter

2008-01-01

Full text: After many years in the economic doldrums the world's uranium industry is undergoing a renaissance. The recent rapid price increase for the product and the anticipated market shortfalls in supply of yellowcake have are responsible for this. There is now a rush of new activity: abandoned mines from a previous era are being re-examined for their potential to be re-opened; planning for exploitation of known but undeveloped uranium deposits is proceeding at a rapid pace in many countries new to uranium mining; and finally worldwide exploration activity for uranium is expanding at a great rate with more than 400 companies now claiming to be involved in the uranium mining market. All of there activities have significant implications the radiation protection profession. At every stage of the uranium production cycle, from exploration to mining and processing through to remediation there are requirements for proper radiation protection procedures and regulation. The long period of reduced activity in uranium mining has meant that few young people have been joining the industry over the past 20 years. There is now a shortage of trained and experienced radiation protection professionals associated with the mining industry that cannot be overcome overnight. The paper discusses the development of this situation and the various strategies that are being put in place around the world to improve the situation. In particular the International Atomic Energy Agency has been working with radiation protection authorities and uranium mining industry representatives from around the world to address the issue. The latest developments in this project will be described and the future plans described. (author)

Methodological proposal for defining mining vocation in Venezuelan land-use planning; Propuesta metodologica para definir la vocacion minera en el contexto del ordenamiento territorial venezolano

Mining is an economic activity which is necessary to provide raw materials for the different socio-productive networks of the country. Its application depends on the mineralogical occurrence offered by the geological conditions of an area and requires planning due to the fact that it needs to be located in a geographical space and the environment fragility of this space and the socio-economic and political-institutional legislation at a given moment all have to be taken into account. Therefore, the objective of this research consists of a proposal for a methodological model to define areas with mining adapted to the Venezuelan context of land-use planning, in order to assign mining uses to the most appropriate areas for that goal, considering the selection, assessment and integration of a series of variables and indicators adjusted to the thematic information available.

Summary of environmental impact assessment for the Syncrude Canada Ltd. Aurora Mine

International Nuclear Information System (INIS)

1996-01-01

A summary of the environmental impact assessment for the Syncrude's proposed Aurora Mine was provided. Two mining areas will be opened. Aurora Mine North, located on oil sands leases 10, 12 and 34 will open first followed by the opening of Aurora Mine South, located on Lease 31. Each mining area will contain two extraction facilities, each capable of producing 6.25 million cubic metres of bitumen per year for a total annual capacity of 25 million cubic metres. The areas of land that will be disturbed by development of the Aurora Mines will total 15,171 hectares. The preferred pipeline, roadway and utility corridor and river crossing to be used for the Mine are shown. Production of SO 2 and NO x emissions from the Aurora Mine is expected to be very low, nevertheless, the cumulative effects of emissions from the mines will be addressed in the context of emissions from the existing or proposed oil sand facilities in the area. 7 tabs., 15 figs

Mine drivage in hydraulic mines

Energy Technology Data Exchange (ETDEWEB)

Ehkber, B Ya

1983-09-01

From 20 to 25% of labor cost in hydraulic coal mines falls on mine drivage. Range of mine drivage is high due to the large number of shortwalls mined by hydraulic monitors. Reducing mining cost in hydraulic mines depends on lowering drivage cost by use of new drivage systems or by increasing efficiency of drivage systems used at present. The following drivage methods used in hydraulic mines are compared: heading machines with hydraulic haulage of cut rocks and coal, hydraulic monitors with hydraulic haulage, drilling and blasting with hydraulic haulage of blasted rocks. Mining and geologic conditions which influence selection of the optimum mine drivage system are analyzed. Standardized cross sections of mine roadways driven by the 3 methods are shown in schemes. Support systems used in mine roadways are compared: timber supports, roof bolts, roof bolts with steel elements, and roadways driven in rocks without a support system. Heading machines (K-56MG, GPKG, 4PU, PK-3M) and hydraulic monitors (GMDTs-3M, 12GD-2) used for mine drivage are described. Data on mine drivage in hydraulic coal mines in the Kuzbass are discussed. From 40 to 46% of roadways are driven by heading machines with hydraulic haulage and from 12 to 15% by hydraulic monitors with hydraulic haulage.

Hydrogeology baseline study Aurora Mine

International Nuclear Information System (INIS)

1996-01-01

A baseline hydrogeologic study was conducted in the area of Syncrude's proposed Aurora Mine in order to develop a conceptual regional hydrogeologic model for the area that could be used to understand groundwater flow conditions. Geologic information was obtained from over 2,000 coreholes and from data obtained between 1980 and 1996 regarding water level for the basal aquifer. A 3-D numerical groundwater flow model was developed to provide quantitative estimates of the potential environmental impacts of the proposed mining operations on the groundwater flow system. The information was presented in the context of a regional study area which encompassed much of the Athabasca Oil Sands Region, and a local study area which was defined by the lowlands of the Muskeg River Basin. Characteristics of the topography, hydrology, climate, geology, and hydrogeology of the region are described. The conclusion is that groundwater flow in the aquifer occurs mostly in a westerly direction beneath the Aurora Mine towards its inferred discharge location along the Athabasca River. Baseflow in the Muskeg River is mostly related to discharge from shallow surficial aquifers. Water in the river under baseflow conditions was fresh, of calcium-carbonate type, with very little indication of mineralization associated with deeper groundwater in the Aurora Mine area. 44 refs., 5 tabs., 31 figs

Acid mine drainage in South Africa: A test of legitimacy theory

Directory of Open Access Journals (Sweden)

Boitumelo Loate

2015-04-01

Full Text Available There is a large body of international literature which suggests that there is a correlation between organisational legitimacy, the nature and extent of non-financial disclosures in corporate reports, and the society’s awareness of social, governance and environmental concerns. Little studied, however, is corporate reporting in South Africa through the lens of legitimacy theory. This paper addresses this gap by exploring whether local mining companies are providing additional environmental information in their annual or integrated reports following media coverage on acid mine drainage and, if so, to what extent. A review of press articles released by the mining houses also reveals how claims to pragmatic, moral and cognitive legitimacy are employed to mitigate negative publicity. In this way, the paper offers additional material on the role of legitimacy theory for explaining developments in corporate reporting. It also contributes to the limited body of interpretive corporate governance research in a South African context.

Advisibility of excavating an additional central shaft to reduce duration of mine construction. [USSR

Energy Technology Data Exchange (ETDEWEB)

Durov, E.M.

1981-09-01

This paper evaluates methods of reducing duration and cost of underground black coal mine construction. A proposed scheme of coal deposit opening by a system of three mine shafts is critically analyzed. In comparison to the conventional scheme, the proposed one has one additional mine shaft in the central mine zone. The shaft, equipped with a cage hoisting system, permits the rate of mine drivage in the center of the mine to be increased. The cage hoisting system in the additional shaft is activated before the main skip shaft has been equipped and is in operation. Duration of mine construction is reduced by 6 to 10 months. Exacavation of the additional shaft costs from 2.5 to 3.5 million rubles. A further system of mine construction is also analyzed. The main shaft in the mine center is temporarily equipped with a cage hoisting system. The cage system is used for hoisting rocks removed from mine headings and main workings constructed at the bottom of the main shaft. The main shaft is equipped with skips and hoisting tower at a later stage when construction of main roadways and structures at its bottom has been completed. The proposed system permits mine construction to be reduced by 4 to 5 months without a major increase in investment.

The safe production of coalmine can be further improved by forecasting the quantity of gas emission based on the real-time data and historical data which the gas monitoring system has saved. By making use of the advantages of data warehouse and data mining technology for processing large quantity of redundancy data, the method and its application of forecasting mine gas emission quantity based on FDM were studied. The constructing fuzzy resembling relation and clustering analysis were proposed, which the potential relationship inside the gas emission data may be found. The mode finds model and forecast model were presented, and the detailed approach to realize this forecast was also proposed, which have been applied to forecast the gas emission quantity efficiently.

Conscience claims, metaphysics, and avoiding an LGBT eugenic.

Science.gov (United States)

Brummett, Abram

2018-06-01

Novel assisted reproductive technologies (ART) are poised to present our society with strange new ethical questions, such as whether lesbian, gay, bisexual, and transgender (LGBT) couples should be allowed to produce children biologically related to both parents, or whether trans-women who want to experience childbirth should be allowed to receive uterine transplants. Clinicians opposed to offering such technologies to LGBT couples on moral grounds are likely to seek legal shelter through the conscience clauses enshrined in U.S. law. This paper begins by briefly discussing some novel ART on the horizon and noting that it is unclear whether current conscience clauses will permit fertility clinics to deny such services to LGBT individuals. A compromise approach to conscience is any view that sees the value of respecting conscience claims within limits. I describe and critique the constraints proposed in the recent work of Wicclair, NeJaime and Siegel as ultimately begging the question. My purpose is to strengthen their arguments by suggesting that in the controversial situations that elicit claims of conscience, bioethicists should engage with the metaphysical claims in play. I argue that conscience claims against LGBT individuals ought to be constrained because the underlying metaphysic-that God has decreed the LGBT lifestyle to be sinful-is highly implausible from the perspective of a naturalized metaphysic, which ought to be the lens through which we evaluate conscience claims. © 2018 John Wiley & Sons Ltd.

Detecting Structural Damage of Nuclear Power Plant by Interactive Data Mining Approach

International Nuclear Information System (INIS)

Yufei Shu

2006-01-01

This paper presents a nonlinear structural damage identification technique, based on an interactive data mining approach, which integrates a human cognitive model in a data mining loop. A mining control agent emulating human analysts is developed, which directly interacts with the data miner, analyzing and verifying the output of the data miner and controlling the data mining process. Additionally, an artificial neural network method, which is adopted as a core component of the proposed interactive data mining method, is evolved by adding a novelty detecting and retraining function for handling complicated nuclear power plant quake-proof data. Plant quake-proof testing data has been applied to the system to show the validation of the proposed method. (author)

Framing and Claiming: How Information-Framing Affects Expected Social Security Claiming Behavior.

Science.gov (United States)

Brown, Jeffrey R; Kapteyn, Arie; Mitchell, Olivia S

2016-03-01

This paper provides evidence that Social Security benefit claiming decisions are strongly affected by framing and are thus inconsistent with expected utility theory. Using a randomized experiment that controls for both observable and unobservable differences across individuals, we find that the use of a "breakeven analysis" encourages early claiming. Respondents are more likely to delay when later claiming is framed as a gain, and the claiming age is anchored at older ages. Additionally, the financially less literate, individuals with credit card debt, and those with lower earnings are more influenced by framing than others.

Information mining in remote sensing imagery

Science.gov (United States)

Li, Jiang

The volume of remotely sensed imagery continues to grow at an enormous rate due to the advances in sensor technology, and our capability for collecting and storing images has greatly outpaced our ability to analyze and retrieve information from the images. This motivates us to develop image information mining techniques, which is very much an interdisciplinary endeavor drawing upon expertise in image processing, databases, information retrieval, machine learning, and software design. This dissertation proposes and implements an extensive remote sensing image information mining (ReSIM) system prototype for mining useful information implicitly stored in remote sensing imagery. The system consists of three modules: image processing subsystem, database subsystem, and visualization and graphical user interface (GUI) subsystem. Land cover and land use (LCLU) information corresponding to spectral characteristics is identified by supervised classification based on support vector machines (SVM) with automatic model selection, while textural features that characterize spatial information are extracted using Gabor wavelet coefficients. Within LCLU categories, textural features are clustered using an optimized k-means clustering approach to acquire search efficient space. The clusters are stored in an object-oriented database (OODB) with associated images indexed in an image database (IDB). A k-nearest neighbor search is performed using a query-by-example (QBE) approach. Furthermore, an automatic parametric contour tracing algorithm and an O(n) time piecewise linear polygonal approximation (PLPA) algorithm are developed for shape information mining of interesting objects within the image. A fuzzy object-oriented database based on the fuzzy object-oriented data (FOOD) model is developed to handle the fuzziness and uncertainty. Three specific applications are presented: integrated land cover and texture pattern mining, shape information mining for change detection of lakes, and

An Incremental High-Utility Mining Algorithm with Transaction Insertion

Science.gov (United States)

Gan, Wensheng; Zhang, Binbin

2015-01-01

Association-rule mining is commonly used to discover useful and meaningful patterns from a very large database. It only considers the occurrence frequencies of items to reveal the relationships among itemsets. Traditional association-rule mining is, however, not suitable in real-world applications since the purchased items from a customer may have various factors, such as profit or quantity. High-utility mining was designed to solve the limitations of association-rule mining by considering both the quantity and profit measures. Most algorithms of high-utility mining are designed to handle the static database. Fewer researches handle the dynamic high-utility mining with transaction insertion, thus requiring the computations of database rescan and combination explosion of pattern-growth mechanism. In this paper, an efficient incremental algorithm with transaction insertion is designed to reduce computations without candidate generation based on the utility-list structures. The enumeration tree and the relationships between 2-itemsets are also adopted in the proposed algorithm to speed up the computations. Several experiments are conducted to show the performance of the proposed algorithm in terms of runtime, memory consumption, and number of generated patterns. PMID:25811038

Bills, Donald J.; Brown, Kristin M.; Alpine, Andrea E.; Otton, James K.; Van Gosen, Bradley S.; Hinck, Jo Ellen; Tillman, Fred D.

2011-01-01

About 1 million acres of Federal land in the Grand Canyon region of Arizona were temporarily withdrawn from new mining claims in July 2009 by the Secretary of the Interior because of concern that increased uranium mining could have negative impacts on the land, water, people, and wildlife. During a 2-year interval, a Federal team led by the Bureau of Land Management is evaluating the effects of withdrawing these lands for extended periods. As part of this team, the U.S. Geological Survey (USGS) conducted a series of short-term studies to examine the historical effects of breccia-pipe uranium mining in the region. The USGS studies provide estimates of uranium resources affected by the possible land withdrawal, examine the effects of previous breccia-pipe mining, summarize water-chemistry data for streams and springs, and investigate potential biological pathways of exposure to uranium and associated contaminants. This fact sheet summarizes results through December 2009 and outlines further research needs.

A raptor study for the proposed Grandy Brook Station to Hope Brook Mine transmission line environmental impact statement

Energy Technology Data Exchange (ETDEWEB)

1986-01-01

The proposed Grandy Brook Station to Hope Brook mine transmission line study area occupies a remote area of south-central Newfoundland. Raptors have been identified as a valued ecosystem component which may be adversely affected. Since little information on population numbers and activities in the study area is available, a survey was conducted to determine raptor use of the proposed route to minimize adverse impacts of the development. Field data was the primary information source, although government officials were consulted for additional information and data files were accessed. Raptors were recorded by species and age class, and apparent activity. One field trip, composed of a ground survey and a helicopter survey, was conducted on July 12, 1986. Suggestions are made for mitigation measures related to such negative aspects as electrocution during construction and maintenance activities, harassment and persecution, collisions with the lines, and electric fields and corona.

Critical analysis of the Colombian mining legislation

Vargas P, Elkin; Gonzalez S, Carmen Lucia

2003-01-01

The document analyses the Colombian mining legislation, Act 685 of 2001, based on the reasons expressed by the government and the miners for its conceit and approval. The document tries to determine the developments achieved by this new Mining Code considering international mining competitiveness and its adaptation to the constitutional rules about environment, indigenous communities, decentralization and sustainable development. The analysis formulates general and specific hypothesis about the proposed objectives of the reform, which are confronted with the arguments and critical evaluations of the results. Most hypothesis are not verified, thus demonstrating that the Colombian mining legislation is far from being the necessary instrument to promote mining activities, making it competitive according to international standards and adapted to the principles of sustainable development, healthy environment, community participation, ethnic minorities and regional autonomy

The Australian Government policy is to ensure that uranium mining, milling and rehabilitation is based on world best practice standards. A best practice guide for in situ recovery (ISR) uranium mining has been developed to communicate the Australian Government's expectations with a view to achieving greater certainty that ISR mining projects meet Australian Government policy and consistency in the assessment of ISR mine proposals within multiple government regulatory processes. The guide focuses on the main perceived risks; impacts on groundwaters, disposal of mining residues, and radiation protection. World best practice does not amount to a universal template for ISR mining because the characteristics of individual ore bodies determine the best practice. (author)

The environmental impact assessment of uranium mining in Australia

International Nuclear Information System (INIS)

Morvell, G.

2002-01-01

Federal environmental impact assessment legislation has existed in Australia since 1974. A number of uranium mines have been developed in this time, utilizing a range of mining techniques, including opencut, underground and in-situ leach. Projects have also been undertaken in a variety of geographical areas requiring consideration of diverse biodiversity, cultural heritage and social impact issues. Assessment of uranium mining proposals in Australia is also conducted in a climate of political opposition from a cross section of the Australian community. This paper outlines some of the key issues that arose during recent assessments and which provide a lead to the role of environmental impact assessment in environmental policy development. Issues are also relevant to recent assessments on a replacement nuclear reactor, shipments of waste for reprocessing and proposed assessments on proposals for low and intermediate level nuclear waste facilities.

Zingano, Andre Cezar; Koppe, Jair Carlos; Costa, Joao Felipe C.L. [Universidade Federal do Rio Grande do Sul, Porto Alegre (Brazil)

2007-07-01

The function of the barrier pillar is to protect the mining panel in activity from the abutment load of adjacent mining panels that were mined. In the case of underground mines in Santa Catarina State, the barrier pillar has functioned to protect the main entries of the mine against pillar failure from old mining panels. The objective of this paper is to verify the application of the empirical method to design barrier pillars as proposed by Peng (1986), using numerical simulation following the mining geometry of the coal mines in Santa Catarina State. Two-dimensional numerical models were built taking into account the geometry of the main entries and mining panels for different overburden thickness, and considering the geomechanical properties for the rock mass that forms the roof-pillar-floor system for the Bonito coal vein. The results of the simulations showed that the empirical method to determine the barrier pillar width is valid for the studied coal vein and considered mine geometry. Neither did the pillar at the main entry become overstressed due to adjacent mine panels, nor did the roof present any failure due to stress redistribution. 9 refs., 6 figs., 5 tabs.

THE METHOD OF ASSESSING ROCK BURSTING HAZARD IN MINING

Directory of Open Access Journals (Sweden)

Anna MANOWSKA

2015-04-01

Full Text Available The article discusses a concept of forecasting accident risk during longwall extraction in crump-risk conditions. In Polish mines rock burst hazard can be described as high compared to other mines around the world. It's related to increase of depth of longwall field operation, preparation works, including drilling of mine face pavements which leads to systematic deterioration of geological and mining conditions. Depletion of coal is also the reason why mines operate in high mining tremor risk conditions. Mines more and more often operate in decks, where there is large number of edges and remains of older decks. Rocks bursts still remain one of the most dangerous natural hazards and therefore are fundamental prob-lem and have the greatest impact on safety in mining industry. The proposed method for forecasting accidents and loss-es in people and goods can contribute to improvement of work organization methods and mine safety management system.

Development of a time-dependent energy model to calculate the mining-induced stress over gates and pillars

Directory of Open Access Journals (Sweden)

2015-06-01

Full Text Available Generally, longwall mining-induced stress results from the stress relaxation due to destressed zone that occurs above the mined panel. Knowledge of induced stress is very important for accurate design of adjacent gateroads and intervening pillars which helps to raise the safety and productivity of longwall mining operations. This study presents a novel time-dependent analytical model for determination of the longwall mining-induced stress and investigates the coefficient of stress concentration over adjacent gates and pillars. The model is developed based on the strain energy balance in longwall mining incorporated to a rheological constitutive model of caved materials with time-varying parameters. The study site is the Tabas coal mine of Iran. In the proposed model, height of destressed zone above the mined panel, total longwall mining-induced stress, abutment angle, induced vertical stress, and coefficient of stress concentration over neighboring gates and intervening pillars are calculated. To evaluate the effect of proposed model parameters on the coefficient of stress concentration due to longwall mining, sensitivity analysis is performed based on the field data and experimental constants. Also, the results of the proposed model are compared with those of existing models. The comparative results confirm a good agreement between the proposed model and the in situ measurements. According to the obtained results, it is concluded that the proposed model can be successfully used to calculate the longwall mining-induced stress. Therefore, the optimum design of gate supports and pillar dimensions would be attainable which helps to increase the mining efficiency.

Formalizing Probabilistic Safety Claims

Science.gov (United States)

Herencia-Zapana, Heber; Hagen, George E.; Narkawicz, Anthony J.

2011-01-01

A safety claim for a system is a statement that the system, which is subject to hazardous conditions, satisfies a given set of properties. Following work by John Rushby and Bev Littlewood, this paper presents a mathematical framework that can be used to state and formally prove probabilistic safety claims. It also enables hazardous conditions, their uncertainties, and their interactions to be integrated into the safety claim. This framework provides a formal description of the probabilistic composition of an arbitrary number of hazardous conditions and their effects on system behavior. An example is given of a probabilistic safety claim for a conflict detection algorithm for aircraft in a 2D airspace. The motivation for developing this mathematical framework is that it can be used in an automated theorem prover to formally verify safety claims.

Evaluating Water Management Practice for Sustainable Mining

Directory of Open Access Journals (Sweden)

Xiangfeng Zhang

2014-02-01

Full Text Available To move towards sustainable development, the mining industry needs to identify better mine water management practices for reducing raw water use, increasing water use efficiency, and eliminating environmental impacts in a precondition of securing mining production. However, the selection of optimal mine water management practices is technically challenging due to the lack of scientific tools to comprehensively evaluate management options against a set of conflicting criteria. This work has provided a solution to aid the identification of more sustainable mine water management practices. The solution includes a conceptual framework for forming a decision hierarchy; an evaluation method for assessing mine water management practices; and a sensitivity analysis in view of different preferences of stakeholders or managers. The solution is applied to a case study of the evaluation of sustainable water management practices in 16 mines located in the Bowen Basin in Queensland, Australia. The evaluation results illustrate the usefulness of the proposed solution. A sensitivity analysis is performed according to preference weights of stakeholders or managers. Some measures are provided for assessing sensitivity of strategy ranking outcomes if the weight of an indicator changes. Finally, some advice is given to improve the mine water management in some mines.

Candia, R. C.; Hennies, W. T.; Azevedo, R. c.; Almeida, I.G.; Soto, J. F.

2010-01-01

Although reductions in the tax of injuries and accidents have been observed in recent years, Mining is still one of the highest risks industries. The basic causes for occurrence of fatalities can be attributed to unsafe conditions and unsafe acts. In this scene is necessary to identify safety problems and to aim the effective solutions. On the other hand, the developing countries dependence on primary industries as mining is evident. In the Peruvian economy, approximately 16% of the GNP and more than 50% of the exportations are due to the mining sector, detaching its competitive position in the worldwide mining. This paper presents fatal accidents analysis in the Peruvian mining industry, having as basis the register of occurred fatal accidents since year 2000 until 2007, identifying the main types of accidents occurred. The source of primary information is the General Mining Direction (DGM) of the Peruvian Mining and Energy Ministry (MEM). The majority of victims belongs to tertiary contractor companies that render services for mine companies. The results of the analysis show also that the majority of accidents happened in the underground mines, and that it is necessary to propose effective solutions to manage risks, aiming at reducing the fatal accidents taxes.

Marcy, A.D.; Scheibner, B.J.; Toews, K.L.; Boldt, C.M.K.

1994-01-01

The Midnite Mine is an inactive, hard-rock uranium mine in Stevens County, WA. Oxidation of sulfide-containing minerals, primarily pyrite, in the ore body produces large quantities of acidic water. An interception system installed by the mining company limits the discharge of contaminated water from the mine. The US Bureau of Indian Affairs (BIA) and the US Bureau of Land Management (BLM) have been actively involved in planning remediation of the disturbed areas. To assist in remediation, the US Bureau of Mines (USBM) initiated research to determine water quality and to define ground water flow characteristics. USBM personnel designed a monitoring network, supervised installation of sampling wells, and collected and analyzed water samples. This Report of Investigations described interpretation of data collected between December 1989 and April 1992. The computer program WATEQ4F was used to identify aqueous species distribution and to calculate potential solid phase controls of solubility. To assist in interpretation of changes in water quality between sampling locations and to develop models describing proposed flow paths, the computer program BALANCE was used. Using output from these programs and field observations, a description of the chemistry along proposed ground water flow paths at the mine is presented

WildSpan: mining structured motifs from protein sequences

Directory of Open Access Journals (Sweden)

Chen Chien-Yu

2011-03-01

Full Text Available Abstract Background Automatic extraction of motifs from biological sequences is an important research problem in study of molecular biology. For proteins, it is desired to discover sequence motifs containing a large number of wildcard symbols, as the residues associated with functional sites are usually largely separated in sequences. Discovering such patterns is time-consuming because abundant combinations exist when long gaps (a gap consists of one or more successive wildcards are considered. Mining algorithms often employ constraints to narrow down the search space in order to increase efficiency. However, improper constraint models might degrade the sensitivity and specificity of the motifs discovered by computational methods. We previously proposed a new constraint model to handle large wildcard regions for discovering functional motifs of proteins. The patterns that satisfy the proposed constraint model are called W-patterns. A W-pattern is a structured motif that groups motif symbols into pattern blocks interleaved with large irregular gaps. Considering large gaps reflects the fact that functional residues are not always from a single region of protein sequences, and restricting motif symbols into clusters corresponds to the observation that short motifs are frequently present within protein families. To efficiently discover W-patterns for large-scale sequence annotation and function prediction, this paper first formally introduces the problem to solve and proposes an algorithm named WildSpan (sequential pattern mining across large wildcard regions that incorporates several pruning strategies to largely reduce the mining cost. Results WildSpan is shown to efficiently find W-patterns containing conserved residues that are far separated in sequences. We conducted experiments with two mining strategies, protein-based and family-based mining, to evaluate the usefulness of W-patterns and performance of WildSpan. The protein-based mining mode

Applicability of gassy mine regulations: Engineering study report

International Nuclear Information System (INIS)

1987-08-01

This study reviewed three bodies of current Mine Safety and Health Administration (MSHA) gassy mine regulations, to address whether the Code of Federal Regulations (CFR) Title 30, Part 57 Safety and Health Standards - Metal and Nonmetal Underground Mines, Section 21-Gassy Mines, or Parts 75 Mandatory Safety Standards - Underground Coal Mines, and Part 77 Mandatory Safety Standards - Surface Coal Mines and Surface Work Areas of Underground Coal Mines, are more applicable to a subsurface repository design. Part 57.21 is determined to be most applicable. There are, however, three sections in Parts 75 and 77 which address certain applicable items in greater detail and, therefore, will provide a more conservative design approach in these areas than Part 57.21, and should be incorporated into the basis for design. Study work also revealed that proposed CFR Title 30, Part 58 Mine Safety and Health - Metal and Nonmetal Standards, will have to be considered during design work if and when these have been promulgated. 9 refs., 1 fig., 1 tab

Amelioration and reforestation of sulfurous mine soils in Lusatia (eastern Germany)

International Nuclear Information System (INIS)

Katzur, J.; Haubold-Rosar, M.

1996-01-01

In Germany nearly 1.550 km 2 have been claimed by brown coal mining until now. Mine soils formed of carboniferous and sulfurous overburden are classified as sulfurous mine soils. They remain vegetation-free for decades and may be cultivated only after soil amelioration. The objective of amelioration is a sustained improvement of soil reaction. Lime requirement for the achievement of a certain pH-value is calculated from acid-base-balance (SBB). Lime fertilizers and base-rich brown coal ashes are used for amelioration. As ashes have several advantages, their application is recommended. The ameliorative application of lime fertilizer or brown coal ash should be incorporated intensively into the soil to a depth of 60 cm, better 100 cm. Amelioration includes a mineral fertilization with N, P and K. Afforestation with Pinus sylvestris, Pinus nigra, Larix decidua, Larix eurolepis. Tilia cordata, Quercus rubra and Quercus petraea on ameliorated mine soils show surprising good results. Multi-species stands have very positive effects on soil formation. Raw humus is formed under pine and larch, and under deciduous trees moder and mull with higher bioactivity and better development of water and nutrient balance in the topsoil are found. 55 refs., 6 figs., 4 tabs

Development of brown coal mining in the Federal Republic of Germany

Energy Technology Data Exchange (ETDEWEB)

Tilmann, W

1985-01-01

The significance of brown coal mining in the Federal Republic of Germany for the development of opencast technology and the power industry is discussed with emphasis on mining in the Rhineland Area. In 1984, 126.7 mt of brown coal were produced in the Federal Republic of Germany. In the development of high-performance equipment it is essential that the efficiency of the bucket-wheel excavator is increased. Trains and conveyors are mainly used for mine transport in the Federal Republic of Germany. A high moral commitment is linked to land claims, recultivation and environmental issues on the part of brown coal mining. In 1984 the percentage share of brown coal supplied to the public power stations was 83.6%, corresponding to 105.9 mt. The installed capacity of all brown coal power stations amounted to 12,764 MW at the end of 1984, providing around one quarter of overall public power output. Charge coal for coal refining has become more important and the production of brown coal dust and brown coal coke has also increased. The share of brown coal in domestic primary energy production is currently around 24% of 151 mt hard-coal units or around 10% of 376.5 mt hard-coal units in terms of energy consumption. 12 references.

Pulker, Claire Elizabeth; Scott, Jane Anne; Pollard, Christina Mary

2018-01-01

To objectively evaluate voluntary nutrition and health claims and marketing techniques present on packaging of high-market-share ultra-processed foods (UPF) in Australia for their potential impact on public health. Cross-sectional. Packaging information from five high-market-share food manufacturers and one retailer were obtained from supermarket and manufacturers' websites. Ingredients lists for 215 UPF were examined for presence of added sugar. Packaging information was categorised using a taxonomy of nutrition and health information which included nutrition and health claims and five common food marketing techniques. Compliance of statements and claims with the Australia New Zealand Food Standards Code and with Health Star Ratings (HSR) were assessed for all products. Almost all UPF (95 %) contained added sugars described in thirty-four different ways; 55 % of UPF displayed a HSR; 56 % had nutrition claims (18 % were compliant with regulations); 25 % had health claims (79 % were compliant); and 97 % employed common food marketing techniques. Packaging of 47 % of UPF was designed to appeal to children. UPF carried a mean of 1·5 health and nutrition claims (range 0-10) and 2·6 marketing techniques (range 0-5), and 45 % had HSR≤3·0/5·0. Most UPF packaging featured nutrition and health statements or claims despite the high prevalence of added sugars and moderate HSR. The degree of inappropriate or inaccurate statements and claims present is concerning, particularly on packaging designed to appeal to children. Public policies to assist parents to select healthy family foods should address the quality and accuracy of information provided on UPF packaging.

For the pending National Claims Database in Japan, researchers will not have access to death information in the enrollment files. We developed and evaluated a claims-based definition of death. We used healthcare claims and enrollment data between January 2005 and August 2009 for 195,193 beneficiaries aged 20 to 74 in 3 private health insurance unions. We developed claims-based definitions of death using discharge or disease status and Charlson comorbidity index (CCI). We calculated sensitivity, specificity and positive predictive values (PPVs) using the enrollment data as a gold standard in the overall population and subgroups divided by demographic and other factors. We also assessed bias and precision in two example studies where an outcome was death. The definition based on the combination of discharge/disease status and CCI provided moderate sensitivity (around 60%) and high specificity (99.99%) and high PPVs (94.8%). In most subgroups, sensitivity of the preferred definition was also around 60% but varied from 28 to 91%. In an example study comparing death rates between two anticancer drug classes, the claims-based definition provided valid and precise hazard ratios (HRs). In another example study comparing two classes of anti-depressants, the HR with the claims-based definition was biased and had lower precision than that with the gold standard definition. The claims-based definitions of death developed in this study had high specificity and PPVs while sensitivity was around 60%. The definitions will be useful in future studies when used with attention to the possible fluctuation of sensitivity in some subpopulations.

2018-04-01

Full Text Available Extractive industries are often claimed to contribute to both poverty reduction and economic growth. Yet, there is also a body of research that suggests natural resource dependence can result in limited development, environmental degradation and social upheaval. This paper examines differences in the socioeconomic and environmental state of mining and non-mining communities in rural Vietnam in order to understand the extent to which mining contributes to livelihood development and socioeconomic well-being. In particular, we examine the role that “corporate social responsibility” (CSR plays in supporting community development in Phuoc Son and Phu Ninh districts, Quang Nam province. Content analysis of newspapers, government documents and mining company reports provided a contextual overview of mining operations and community relations in each study area. Semi-structured interviews were used to collect information from local and regional stakeholders to further understand perceived impacts of mining operations on local communities. Our study finds that in comparison to non-mining communities, communities with active mines demonstrated increased job development, decreased poverty rates, enhanced infrastructure and social development along with increased incidences of CSR initiatives. However, a number of adverse effects from mining activities were reported including environmental degradation (e.g., deforestation, water pollution, etc. increased criminal activity and drug addiction. Dependence on mine-related employment in local communities becomes acutely apparent when temporary mine closures result in widespread unemployment. Local governments may be the greatest beneficiaries of mining with increased tax revenues and enhanced management potential of leased land. Non-mining communities without direct benefits from mining activities maintained economic diversity and were therefore more resilient to economic shocks such as nearby mine closures.

Plan for injection of coal combustion byproducts into the Omega Mine for the reduction of acid mine drainage

International Nuclear Information System (INIS)

Gray, T.A.; Moran, T.C.; Broschart, D.W.; Smith, G.A.

1998-01-01

The Omega Mine Complex is located outside of Morgantown, West Virginia. The mine is in the Upper Freeport Coal, an acid-producing coal seam. The coal was mined in a manner that has resulted in acid mine drainage (AMD) discharges at multiple points. During the 1990's, the West Virginia Division of Environmental Protection (WVDEP) assumed responsibility for operating a collection and treatment system for the AMD. Collection and treatment costs are approximately $300,000 per year. Injecting grout into the mine workings to reduce AMD (and thus reducing treatment costs) is proposed. The procedure involves injecting grout mixes composed primarily of coal combustion byproducts (CCB's) and water, with a small quantity of cement. The intention of the injection program is to fill the mine voids in the north lobe of the Omega Mine (an area where most of the acidity is believed to be generated) with the grout, thus reducing the contact of air and water with potentially acidic material. The grout mix design consists of an approximate 1:1 ratio of fly ash to byproducts from fluidized bed combustion. Approximately 100 gallons of water per cubic yard of grout is used to achieve flowability. Observation of the mine workings via subsurface borings and downhole video camera confirmed that first-mined areas were generally open while second-mined areas were generally partially collapsed. The injection program was developed to account for this by utilizing closer injection hole spacing in second-mined areas. Construction began in January 1998, with grout injection expected to commence in mid-April 1998

Microbial decontamination of uranium mine drainage

International Nuclear Information System (INIS)

Hard, B.C.; Babel, W.

2001-01-01

One of the problems one is faced with when uranium mines are closed is the decontamination of acid mine drainage (AMD) from tailings and flooding of the underground mines. The high concentrations of sulfates and metals in mining water make it impossible to dispose of the water into rivers without having to decontaminate it first. A bioremediation process is proposed in which sulfate-reducing bacteria are used to remove metals, neutralize the water and reduce the sulfate concentrations. Methylotrophic sulfate-reducing strains have been isolated which can be used in such a process. Lab scale experiments with different reactor types were carried out in order to find the optimum design for this bioremediation process. Comparisons were made between methanol and other electron donors with regards to their suitability as substrate for this process. Methanol was found to be most suited. Laboratory data suggest that immobilizing the bacteria on pumice particles increases the sulfate-reduction rate (SRR) up to three fold to 18 mg/l.h, compared to the rates of free flowing cells of between 3.7 and 6.8 mg/l.h. Preliminary experiments on a larger scale (15 l) using acid mine drainage pH 2.5 show SRR of 0.71 mg/l.h. In biosorption experiments up to 140 mg of aluminium per g biomass was removed from the water. One strain was found to reduce uranium VI, thus changing it from the soluble to the insoluble form. The application of the proposed process with regards to bioremediation of AMD are discussed. (orig.)

Limitations in small artisanal gold mining addressed by educational components paired with alternative mining methods.

Science.gov (United States)

Zolnikov, Tara R

2012-03-01

Current solutions continue to be inadequate in addressing the longstanding, worldwide problem of mercury emissions from small artisanal gold mining. Mercury, an inexpensive and easily accessible heavy metal, is used in the process of extracting gold from ore. Mercury emissions disperse, affecting human populations by causing adverse health effects and environmental and social ramifications. Many developing nations have sizable gold ore deposits, making small artisanal gold mining a major source of employment in the world. Poverty drives vulnerable, rural populations into gold mining because of social and economic instabilities. Educational programs responding to this environmental hazard have been implemented in the past, but have had low positive results due to lack of governmental support and little economic incentive. Educational and enforced intervention programs must be developed in conjunction with governmental agencies in order to successfully eliminate this ongoing problem. Industry leaders offered hopeful suggestions, but revealed limitations when trying to develop encompassing solutions to halt mercury emissions. This research highlights potential options that have been attempted in the past and suggests alternative solutions to improve upon these methods. Some methods include buyer impact recognition, risk assessment proposals exposing a cost-benefit analysis and toxicokinetic modeling, public health awareness campaigns, and the education of miners, healthcare workers, and locals within hazardous areas of mercury exposure. These methods, paired with the implementation of alternative mining techniques, propose a substantial reduction of mercury emissions. Copyright © 2011 Elsevier B.V. All rights reserved.

Incremental Frequent Subgraph Mining on Large Evolving Graphs

KAUST Repository

Abdelhamid, Ehab

2017-08-22

Frequent subgraph mining is a core graph operation used in many domains, such as graph data management and knowledge exploration, bioinformatics and security. Most existing techniques target static graphs. However, modern applications, such as social networks, utilize large evolving graphs. Mining these graphs using existing techniques is infeasible, due to the high computational cost. In this paper, we propose IncGM+, a fast incremental approach for continuous frequent subgraph mining problem on a single large evolving graph. We adapt the notion of “fringe” to the graph context, that is the set of subgraphs on the border between frequent and infrequent subgraphs. IncGM+ maintains fringe subgraphs and exploits them to prune the search space. To boost the efficiency, we propose an efficient index structure to maintain selected embeddings with minimal memory overhead. These embeddings are utilized to avoid redundant expensive subgraph isomorphism operations. Moreover, the proposed system supports batch updates. Using large real-world graphs, we experimentally verify that IncGM+ outperforms existing methods by up to three orders of magnitude, scales to much larger graphs and consumes less memory.

HSM: Heterogeneous Subspace Mining in High Dimensional Data

DEFF Research Database (Denmark)

Müller, Emmanuel; Assent, Ira; Seidl, Thomas

2009-01-01

Heterogeneous data, i.e. data with both categorical and continuous values, is common in many databases. However, most data mining algorithms assume either continuous or categorical attributes, but not both. In high dimensional data, phenomena due to the "curse of dimensionality" pose additional...... challenges. Usually, due to locally varying relevance of attributes, patterns do not show across the full set of attributes. In this paper we propose HSM, which defines a new pattern model for heterogeneous high dimensional data. It allows data mining in arbitrary subsets of the attributes that are relevant...... for the respective patterns. Based on this model we propose an efficient algorithm, which is aware of the heterogeneity of the attributes. We extend an indexing structure for continuous attributes such that HSM indexing adapts to different attribute types. In our experiments we show that HSM efficiently mines...

Radon exhaustion and ventilation are surely regarded as key links for safety production and radiation protection in underground uranium mines, and the crucial point to achieve safety production goals lies in timely and accurately adjusting and controlling of ventilation technical measures and ventilation system management with the changing operation conditions of mines. This paper proposes corresponding countermeasures based on the respectively systematical analysis of daily ventilation management, ventilation facilities and structures management, and ventilation system information management in uranium mines. Furthermore, standardized management approaches and suggestions are put forward to realize standardization of uranium mines' ventilation management and radon exhaustion technique. (authors)

2009-01-01

Ventilation fans are one of the most important pieces of equipment in coal mines. Their performance plays an important role in the safety of staff and production. Given the actual requirements of coal mine production, we instituted a research project on the measurement methods of key performance parameters such as wind pressure, amount of ventilation and power. At the end a virtual instrument for mine ventilation fans performance evaluation was developed using a USB interface. The practical perform-ance and analytical results of our experiments show that it is feasible, reliable and effective to use the proposed instrumentation for mine ventilation performance evaluation.

Claiming health in food products

DEFF Research Database (Denmark)

Lähteenmäki, Liisa

2013-01-01

Health-related information is increasingly used on food products to convey their benefits. Health claims as a subcategory of these messages link the beneficial component, functions or health outcomes with specific products. For consumers, health claims seem to carry the message of increased...... healthiness, but not necessarily making the product more appealing. The wording of the claim seems to have little impact on claim perception, yet the health image of carrier products is important. From consumer-related factors the relevance and attitudes towards functional foods play a role, whereas socio......-demographic factors have only minor impact and the impact seems to be case-dependent. Familiarity with claims and functional foods increase perceived healthiness and acceptance of these products. Apparently consumers make rather rational interpretations of claims and their benefits when forced to assess...

ERA's Ranger uranium mine

1997-01-01

Energy Resource of Australia (ERA) is a public company with 68% of its shares owned by the Australian company North Limited. It is currently operating one major production centre - Ranger Mine which is 260 kilometres east of Darwin, extracting and selling uranium from the Ranger Mine in the Northern Territory to nuclear electricity utilities in Japan, South Korea, Europe and North America. The first drum of uranium oxide from Ranger was drummed in August 1981 and operations have continued since that time. ERA is also in the process of working towards obtaining approvals for the development of a second mine - Jabiluka which is located 20 kilometres north of Ranger. The leases of Ranger and Jabiluka adjoin. The Minister for the Environment has advised the Minister for Resources and Energy that there does not appear to be any environmental issue which would prevent the preferred Jabiluka proposal from proceeding. Consent for the development of ERA's preferred option for the development of Jabiluka is being sought from the Aboriginal Traditional Owners. Ranger is currently the third largest producing uranium mine in the world producing 4,237 tonnes of U 3 O 8 in the year to June 1997

In order to obtain the best social and environmental results from mining activities, different solutions, which involve a variety of perspectives, have been proposed. These include the worldwide perspective based in the economy globalization paradigms; the regional perspective, focused in the integration of countries; the national perspective, which emphasizes the natural assets and development options, and finally a local perspective is incorporated to account for the participation of directly affected communities. Within this framework, the mining industry is requested to develop both technological and managerial tools appropriate to evaluate, optimize and communicate the social and environmental performance and output of its related activities, mainly in the developing countries. On the other hand, the governments have been committed to implement regulatory actions, of command and control type, based on an environmental legislation in line with the above mentioned perspectives and also to use economical instruments as a mean to accomplish environmental objectives. In Colombia the direct regulation methods have been traditionally used to prevent the environmental deterioration produced by mining activities, however, since the 1991 political constitution and the law 99 of 1993, the communities' participation and economical instruments were incorporated. A historic summary of the environmental legislation in our country from the early 70's up to now, showing its implications in mining is presented. Then a favorable tendency is indicated in the environmental improvement of the national extractive industry, accomplished as a result of the implementation of new strategies to minimize the impact of mining on the environment and to improve the well being of local communities

Mueller, R. P.; van Susante, P. J.

2012-01-01

Outer space contains a vast amount of resources that offer virtually unlimited wealth to the humans that can access and use them for commercial purposes. One of the key technologies for harvesting these resources is robotic mining of regolith, minerals, ices and metals. The harsh environment and vast distances create challenges that are handled best by robotic machines working in collaboration with human explorers. Humans will benefit from the resources that will be mined by robots. They will visit outposts and mining camps as required for exploration, commerce and scientific research, but a continuous presence is most likely to be provided by robotic mining machines that are remotely controlled by humans. There have been a variety of extra-terrestrial robotic mining concepts proposed over the last 40 years and this paper will attempt to summarize and review concepts in the public domain (government, industry and academia) to serve as an informational resource for future mining robot developers and operators. The challenges associated with these concepts will be discussed and feasibility will be assessed. Future needs associated with commercial efforts will also be investigated.

2018-04-01

Community mining for complex social networks with link and attribute information plays an important role according to different application needs. In this paper, based on our proposed general non-negative matrix factorization (GNMF) algorithm without dimension matching constraints in our previous work, we propose the joint GNMF with graph Laplacian (LJGNMF) to implement community mining of complex social networks with link and attribute information according to different application needs. Theoretical derivation result shows that the proposed LJGNMF is fully compatible with previous methods of integrating traditional NMF and symmetric NMF. In addition, experimental results show that the proposed LJGNMF can meet the needs of different community minings by adjusting its parameters, and the effect is better than traditional NMF in the community vertices attributes entropy.

Background For the pending National Claims Database in Japan, researchers will not have access to death information in the enrollment files. We developed and evaluated a claims-based definition of death. Methodology/Principal Findings We used healthcare claims and enrollment data between January 2005 and August 2009 for 195,193 beneficiaries aged 20 to 74 in 3 private health insurance unions. We developed claims-based definitions of death using discharge or disease status and Charlson comorbidity index (CCI). We calculated sensitivity, specificity and positive predictive values (PPVs) using the enrollment data as a gold standard in the overall population and subgroups divided by demographic and other factors. We also assessed bias and precision in two example studies where an outcome was death. The definition based on the combination of discharge/disease status and CCI provided moderate sensitivity (around 60%) and high specificity (99.99%) and high PPVs (94.8%). In most subgroups, sensitivity of the preferred definition was also around 60% but varied from 28 to 91%. In an example study comparing death rates between two anticancer drug classes, the claims-based definition provided valid and precise hazard ratios (HRs). In another example study comparing two classes of anti-depressants, the HR with the claims-based definition was biased and had lower precision than that with the gold standard definition. Conclusions/Significance The claims-based definitions of death developed in this study had high specificity and PPVs while sensitivity was around 60%. The definitions will be useful in future studies when used with attention to the possible fluctuation of sensitivity in some subpopulations. PMID:23741526

The construction sector is responsible for a high consumption of natural resources. Moreover, the mining industry generates and discard waste improperly in the environment aggravating environmental problems. In order to reduce the natural sand extraction and provide the environmentally correct disposal of mining waste, this work proposes the use of quartzite mining waste to replace natural sand for the production of adhesive mortars. The quartzite mining tailings was chemically characterized using X-ray fluorescence, and morphologically by optical microscopy. In sequence, the mortars were subjected to characterization tests in the fresh state as consistency index, slip, water retention, entrained air content, bulk density and Squeeze Flow. The results were satisfactory, indicating the viability of this material as fine aggregate in total replacement of natural aggregate, allowing the reduction of environmental impacts. (author)

Handling Dynamic Weights in Weighted Frequent Pattern Mining

Science.gov (United States)

Ahmed, Chowdhury Farhan; Tanbeer, Syed Khairuzzaman; Jeong, Byeong-Soo; Lee, Young-Koo

Even though weighted frequent pattern (WFP) mining is more effective than traditional frequent pattern mining because it can consider different semantic significances (weights) of items, existing WFP algorithms assume that each item has a fixed weight. But in real world scenarios, the weight (price or significance) of an item can vary with time. Reflecting these changes in item weight is necessary in several mining applications, such as retail market data analysis and web click stream analysis. In this paper, we introduce the concept of a dynamic weight for each item, and propose an algorithm, DWFPM (dynamic weighted frequent pattern mining), that makes use of this concept. Our algorithm can address situations where the weight (price or significance) of an item varies dynamically. It exploits a pattern growth mining technique to avoid the level-wise candidate set generation-and-test methodology. Furthermore, it requires only one database scan, so it is eligible for use in stream data mining. An extensive performance analysis shows that our algorithm is efficient and scalable for WFP mining using dynamic weights.

Mining Trust Relationships from Online Social Networks

Institute of Scientific and Technical Information of China (English)

Yu Zhang; Tong Yu

2012-01-01

With the growing popularity of online social network,trust plays a more and more important role in connecting people to each other.We rely on our personal trust to accept recommendations,to make purchase decisions and to select transaction partners in the online community.Therefore,how to obtain trust relationships through mining online social networks becomes an important research topic.There are several shortcomings of existing trust mining methods.First,trust is category-dependent.However,most of the methods overlook the category attribute of trust relationships,which leads to low accuracy in trust calculation.Second,since the data in online social networks cannot be understood and processed by machines directly,traditional mining methods require much human effort and are not easily applied to other applications.To solve the above problems,we propose a semantic-based trust reasoning mechanism to mine trust relationships from online social networks automatically.We emphasize the category attribute of pairwise relationships and utilize Semantic Web technologies to build a domain ontology for data communication and knowledge sharing.We exploit role-based and behavior-based reasoning functions to infer implicit trust relationships and category-specific trust relationships.We make use of path expressions to extend reasoning rules so that the mining process can be done directly without much human effort.We perform experiments on real-life data extracted from Epinions.The experimental results verify the effectiveness and wide application use of our proposed method.

Nuclear regulation of South African mines: An industry perspective

International Nuclear Information System (INIS)

Wymer, D.G.

2001-01-01

South African mines have become subject to a rigid and prescriptive system of nuclear regulation that has its roots in the past when South Africa embarked upon a period of nuclear development spanning the full nuclear fuel cycle, and in which the South African gold mining industry once played a major part in the supply of uranium as a low grade by-product. Radiation hazards in the mines are generally very moderate, even in the few gold mines associated with uranium by-product, and to not warrant the type of regulatory attention normally applied to nuclear installations, or even to uranium mines. The continued imposition of strict nuclear regulatory requirements has caused severe financial hardship and threatens the survival of certain mining operations, while seemingly having little or no health benefits to workers or the public. With the development of modern, comprehensive mine health and safety legislation, a more appropriate, effective, and far less costly vehicle for controlling radiation hazards in mines now exists, utilizing the resources of the Mine Health and Safety Inspectorate. This approach is now being proposed, in the drafting of new legislation, as constituting a better alternative to the nuclear regulation of mines. (author)

The hydrogeology of Sengwa Mine as part of the E.I.A.

Johnstone, A.C. [Groundwater Consulting Services, Johannesburg (South Africa)

1995-12-31

The hydrogeology part of an Environmental Impact Assessment (EIA) study of the feasibility of a proposed mine area in Zimbabwe is described. The EIA was conducted to assess the short term and long term impact of open cast mining at the Sengwa Mine. The purpose is to determine the ground water regime of the mining area for use in predicting the impact of mining operations on ground water and the impact of ground water on the planned mining. The results show that the mining operation will lower the ground water level around the mine by dewatering. An increase of total dissolved content in the ground water due to mining will have an impact on water quality. There is a potential for generation of acid mine drainage in the long run. 5 figs., 4 tabs.

Claims in civil engineering contracts

CERN Document Server

Speirs, N A

1999-01-01

This paper considers claims arising during civil engineering construction contracts. The meaning of the word 'claim' is considered and its possible implications for additional cost and time to completion. The conditions of the construction contract selected will influence the risk apportionment between contractor and client and the price offered by the contractor for the work. Competitive bidding constraints and profit margins in the construction industry, however, may also influence the price offered. This in turn can influence the likelihood of claims arising. The client from his point of view is concerned to complete the work within an agreed time and budget. The circumstances under which claims may arise are reviewed in relation to typical conditions of contract. These circumstances are then related to the CERN LHC civil works. Ways of avoiding claims, where this is possible, are considered. Finally, the means of evaluation of claims and their settlement are considered.

Bogdanovic, Dejan; Nikolic, Djordje; Ilic, Ivana

2012-03-01

Selecting the best mining method among many alternatives is a multicriteria decision making problem. The aim of this paper is to demonstrate the implementation of an integrated approach that employs AHP and PROMETHEE together for selecting the most suitable mining method for the "Coka Marin" underground mine in Serbia. The related problem includes five possible mining methods and eleven criteria to evaluate them. Criteria are accurately chosen in order to cover the most important parameters that impact on the mining method selection, such as geological and geotechnical properties, economic parameters and geographical factors. The AHP is used to analyze the structure of the mining method selection problem and to determine weights of the criteria, and PROMETHEE method is used to obtain the final ranking and to make a sensitivity analysis by changing the weights. The results have shown that the proposed integrated method can be successfully used in solving mining engineering problems.

Cherry, Nicola M; Sithole, Fortune; Beach, Jeremy R; Burstyn, Igor

2010-01-01

Many workers with one Workers' Compensation Board (WCB) claim make further claims. If the characteristics of the job, initial injury or worker were predictive of an early second claim, interventions at the time of return to work after the first claim might be effective in reducing the burden of work-related injury. This report explores the characteristic of those who make a second claim. Records of all Alberta WCB claims from January 1, 1995, to December 31, 2004, for individuals 18 to claim, sex and age of claimant, type of injury, type of accident, occupation, industry, an indicator of company size, and industry claim rate were extracted, as well as the date of any second claim. The likelihood of second claim and mean time to second claim were estimated. Multivariate analyses were performed using Cox regression. 1,047,828 claims were identified from 490,230 individuals. Of these, 49.2% had at least two claims. In the multivariate model a reduced time to second claim was associated with male sex, younger age and some types of injury and accident. Machining trades were at highest risk of early second claim (hazard ratio [HR] 2.54 compared with administration), and of the industry sectors manufacturing was at highest risk (HR 1.37 compared with business, personal and professional services). Some caution is needed in interpreting these data as they may be affected by under-reporting and job changes between claims. Nonetheless, they suggest that there remains room for interventions to reduce the considerable differences in risk of a second claim among workers, jobs and industries.

Determination of Abutment Pressure in Coal Mines with Extremely Thick Alluvium Stratum: A Typical Kind of Rockburst Mines in China

Science.gov (United States)

Zhu, Sitao; Feng, Yu; Jiang, Fuxing

2016-05-01

This paper investigates the abutment pressure distribution in coal mines with extremely thick alluvium stratum (ETAS), which is a typical kind of mines encountering frequent intense rockbursts in China. This occurs due to poor understanding to abutment pressure distribution pattern and the consequent inappropriate mine design. In this study, a theoretical computational model of abutment pressure for ETAS longwall panels is proposed based on the analysis of load transfer mechanisms of key stratum (KS) and ETAS. The model was applied to determine the abutment pressure distribution of LW2302S in Xinjulong Coal Mine; the results of stress and microseismic monitoring verified the rationality of this model. The calculated abutment pressure of LW2302S was also used in the terminal mining line design of LW2301N for rockburst prevention, successfully protecting the main roadway from the adverse influence of the abutment pressure.

Bruha, J.; Slovacek, T.; Berka, J.; Sadilek, P.

1992-01-01

A procedure is proposed for mining sedimentary-type ore deposits, particularly uranium deposits, using the stope-pillar technique. The stope having been mined out, the free room is filled with hydro-setting gob from the surface. A precondition for the application of this technique is horizontal ore mineralization in sediments where the total thickness of the mineralized ore layer is at least 3 to 5 m. Mining losses do not exceed 5%. For thicknesses greater than 5 m, the roof is reinforced and the walls are secured with netting. The assets of the technique include higher labor productivity of the driving, lower material demands in reinforcing and filling, lower power consumption, and reduced use of explosives.

2017-01-01

Full Text Available Corporate social responsibility (CSR in mining areas has increased momentum especially in countries like India where it has been made mandatory. The primary objective of this paper is to document actual social challenges of mining in field areas and find out how companies in the coal sector can work in a systematic manner to achieve uplift of affected communities. The first part of the paper draws evidence from three different bodies of literature, i.e. CSR and coal mining, capacity building and livelihood generation in mining areas. We try to converge the literature to propose a novel framework for livelihood generation work through capacity building with the help of CSR investments. The paper also documents a live case of planning and the implementation of capacity building activities in Muriadih coal mines in the Jharkhand state of India and offers lessons to both business and policy makers. The proposed framework has only been experimented in a local context, yet has the potential to be replicated in other mining areas.

Full Text Available Severe natural conditions and complex terrain make it difficult to apply precise localization in underground mines. In this paper, an anchor-free localization method for mobile targets is proposed based on non-metric multi-dimensional scaling (Multi-dimensional Scaling: MDS and rank sequence. Firstly, a coal mine wireless sensor network is constructed in underground mines based on the ZigBee technology. Then a non-metric MDS algorithm is imported to estimate the reference nodes’ location. Finally, an improved sequence-based localization algorithm is presented to complete precise localization for mobile targets. The proposed method is tested through simulations with 100 nodes, outdoor experiments with 15 ZigBee physical nodes, and the experiments in the mine gas explosion laboratory with 12 ZigBee nodes. Experimental results show that our method has better localization accuracy and is more robust in underground mines.

The gross alpha and gross beta activities were estimated for radiological assessment of surface water quality around the proposed uranium mining site Kylleng Pyndengsohiong Mawthabah (Domiasiat), West Khasi Hills District, Meghalaya situated in a high rainfall area (12,000mm) in India. 189 Surface water samples were collected over different seasons of the year from nine different locations covering around 100km(2). Gross beta activities were found to vary from 144 to 361mBq/L which is much below the prescribed WHO limit of 1000mBq/L for drinking water. Gross alpha activities varied from 61 to 127mBq/L. These values are much below the reported gross alpha values by other countries. In about 7% of the samples the alpha activities remain exceeded the WHO guideline limit of 100mBq/L. Surface water samples collected during the summer season of the year show higher activity whereas low activity was found from samples collected during monsoon season. Results show that all water sources are acceptable as drinking water for human consumption from the radiological point of view, the higher gross alpha concentrations in a few locations remains so only for short duration during the summer season.

Uranium mining generates fuel for the nuclear power plants and it is the main source of income for the region of Caetite-BA. However, Non-Governmental Organizations claim that mining pollutes the environment and jeopardizes human health and safety. Besides uranium, the ground contains significant concentrations of thorium and of all radionuclides of its family, such as radium isotopes. In this framework, we carried out an independent study analyzing the concentration of the radionuclides activities 226, 228 Ra and 234,238 U in water samples and radionuclides 226 Ra, 232 Th and 40 K in soil samples using different techniques of nuclear spectrometry. The selection criteria for the collection points were their proximity to the uranium processing plant and to affluent rivers. The soil samples presented very low concentration of activity for radionuclides investigated, compared to the limits established of the exclusion, exemption and impartiality for radiation protection requirement given by the Regulator Position established by CNEN. The amount of radioisotopes appears consistent with a natural origin, thus it is not possible to state that the mining process in Caetite increases pollution or radiation exposure in a significant way.

2014-01-01

Frequent itemset mining is the important first step of association rule mining, which discovers interesting patterns from the massive data. There are increasing concerns about the privacy problem in the frequent itemset mining. Some works have been proposed to handle this kind of problem. In this paper, we introduce a personalized privacy problem, in which different attributes may need different privacy levels protection. To solve this problem, we give a personalized privacy-preserving method by using the randomized response technique. By providing different privacy levels for different attributes, this method can get a higher accuracy on frequent itemset mining than the traditional method providing the same privacy level. Finally, our experimental results show that our method can have better results on the frequent itemset mining while preserving personalized privacy.

Key Lake mine water spill: further clean-up not required

International Nuclear Information System (INIS)

Potvin, R.

1984-02-01

The Atomic Energy Control Board (AECB) has concluded that no additional remedial measures are warranted with regard to the mine water spill which occurred in early January at the Key Lake Mining Corporation facility in northern Saskatchewan, and has advised the company to reconsider its proposal for clean-up of the adjoining Gerald Lake basin. On January 5, an estimated 87 million litres of mine water was accidentally released to the environment when a water storage reservoir at the mine site overflowed. The spilled water flowed into the adjoining Gerald Lake catchment area where it has remained adequately contained

Concentrated Brine Treatment using New Energy in Coal Mine Evaporation Ponds

Science.gov (United States)

Li, Ting; Li, Jingfeng

2017-12-01

Recently, more and more coal mine water is being advanced treated and reused in China. The concentrated brine that results from advanced treatment methods can only be evaporated in an evaporation pond. Because of limited treatment capabilities and winter freezing, evaporation ponds often overflow, causing environment contamination. In this paper, based on analysis of brine water quality and economic-technical feasibility, we present a suitable treatment method for brine in evaporation ponds as electrodialysis using solar energy. In addition, we propose a new system to treat brine in coal mine evaporation ponds, which is powered by solar and wind. The operating efficiency of this treatment system proposed in this paper can meet the concentrated brine treatment demands in most coal mines in western mining areas of China and it places the photovoltaic power generation plates on the surface of the evaporation pond on a fixed floating island, which reduces any risk associated with land acquisition. This system can enhance brine treatment efficiency, requires a reduced evaporation pond area, increases the utilization of coal mine water, and minimizes the risk of environment contamination.

Statistical methods of estimating mining costs

Science.gov (United States)

Long, K.R.

2011-01-01

Until it was defunded in 1995, the U.S. Bureau of Mines maintained a Cost Estimating System (CES) for prefeasibility-type economic evaluations of mineral deposits and estimating costs at producing and non-producing mines. This system had a significant role in mineral resource assessments to estimate costs of developing and operating known mineral deposits and predicted undiscovered deposits. For legal reasons, the U.S. Geological Survey cannot update and maintain CES. Instead, statistical tools are under development to estimate mining costs from basic properties of mineral deposits such as tonnage, grade, mineralogy, depth, strip ratio, distance from infrastructure, rock strength, and work index. The first step was to reestimate "Taylor's Rule" which relates operating rate to available ore tonnage. The second step was to estimate statistical models of capital and operating costs for open pit porphyry copper mines with flotation concentrators. For a sample of 27 proposed porphyry copper projects, capital costs can be estimated from three variables: mineral processing rate, strip ratio, and distance from nearest railroad before mine construction began. Of all the variables tested, operating costs were found to be significantly correlated only with strip ratio.

From Disparity to Harmonisation of Construction Industry Payment Legislation in Australia: A Proposal for a Dual Process of Adjudication based upon Size of Progress Payment Claim

Directory of Open Access Journals (Sweden)

Jeremy Coggins

2011-06-01

Full Text Available Since the introduction of the Building and Construction Industry Security of Payment Act into New South Wales in 1999, construction industry payment legislation has progressively been enacted on a jurisdiction-by-jurisdiction basis throughout Australia. Of the eight Australian Acts, two distinct legislative models can be discerned – what have been termed the ‘East Coast’ and ‘West Coast’ models. This article compares the two models with respect to their payment systems and adjudication schemes, procedural justice afforded, incursion upon freedom of contract, uptake rates and efficiency. From this comparison, the strengths and weaknesses of the two models are identified. Finally, a dual process of adjudication based on progress payment claim size is proposed for a harmonised model, developed from previous proposals put forward by other authors, which aims to combine the strengths of the two existing models.

An analysis of the preliminary water management proposal for the Ranger Uranium Mine

International Nuclear Information System (INIS)

Gibson, D.K.

1980-07-01

Some of the problems expected to arise as a result of contamination of rainfall run-off by the ore and waste rock heaps of the Ranger Uranium Mine, at Jabiru in the Northern Territory of Australia, have been re-examined. A computer program has been written to estimate the quantity of run-off water resulting from any given rainfall pattern. The program was calibrated against measured stream flows in Gulungul Creek; it was then applied to the two major catchment areas surrounding the mine site, and estimates of the quantity and quality of discharge water were made. The effects of the discharge are discussed in relation to the levels tolerable to fish and, in the case of radium, permitted as uptake by humans. A possible modification to the water management plan, which would increase the time for sedimentation before discharge, is suggested

Computer modelling of an underground mine ventilation system

International Nuclear Information System (INIS)

1984-12-01

The ability to control workplace short-lived radon daughter concentrations to appropriate levels is crucial to the underground mining of uranium ores. Recognizing that mine ventilation models can be used to design ventilation facilities in new mines and to evaluate proposed ventilation changes in existing mines the Atomic Energy Control Board (AECB) initiated this study to first investigate existing mine ventilation models and then develop a suitable model for use by AECB staff. At the start of the study, available literature on mine ventilation models, in partiuclar models suitable for the unique task of predicting radon daughter levels, were reviewed. While the details of the models varied, it was found that the basic calculation procedures used by the various models were similar. Consequently, a model developed at Queen's University that not only already incorporated most of the desired features but was also readily available, was selected for implementation. Subsequently, the Queen's computer program (actually two programs, one for mine ventilation and one to calculate radon daughter levels) was extended and tested. The following report provides the relevant documentation for setting up and running the models. The mathematical basis of the calculational procedures used in the models are also described

Artisanal small-scale mining: Potential ecological disaster in Mzingwane District, Zimbabwe

Directory of Open Access Journals (Sweden)

Siduduziwe Ncube-Phiri

2015-05-01

Full Text Available Artisanal small-scale mining (ASM has devastating impacts on the environment, such as deforestation, over-stripping of overburden, burning of bushes and use of harmful chemicals like mercury. These environmental impacts are a result of destructive mining, wasteful mineral extraction and processing practices and techniques used by the artisanal small-scale miners. This paper explores the ecological problems caused by ASM in Mzingwane District, Zimbabwe. It seeks to determine the nature and extent to which the environment has been damaged by the ASM from a community perspective. Interviews, questionnaires and observations were used to collect qualitative data. Results indicated that the nature of the mining activities undertaken by unskilled and under-equipped gold panners in Mzingwane District is characterised by massive stripping of overburden and burning of bushes, leading to destruction of large tracts of land and river systems and general ecosystem disturbance. The research concluded that ASM in Mzingwane District is an ecological time bomb, stressing the need for appropriate modifications of the legal and institutional frameworks for promoting sustainable use of natural resources and mining development in Zimbabwe. Government, through the Ministry of Small Scale and Medium Enterprises, need to regularise and formalise all gold mining activities through licensing, giving permanent claims and operating permits to panners in order to recoup some of the added costs in the form of taxes. At the local level, the Mzingwane Rural District Council (MRDC together with the Environmental Management Agency (EMA need to design appropriate environmental education and awareness programmes targeting the local community and gold panners.

Serviceability criteria for buildings in mine subsidence area -- Adjustment to Eurocodes

International Nuclear Information System (INIS)

Kawulok, M.; Sulimowski, Z.

1994-01-01

Due to ground deformations caused by underground mining, building structures in mining areas are frequently subjected to considerable deformations and damage to the finishing and structural elements. As a consequence, serviceable values of such structures are distinctly diminished, and in extreme cases, seriously damaged structures may be exempted from further service. These problems are not duly represented in the existing building standard codes. It is also important to determine relationship between damage stage and value of the building, and hence the strategy for reconstruction or renovation works. The paper presents proposals concerning serviceability criteria of building structures in mining areas, in terms of basic standard requirements valid in building in Poland, as well as proposals of Eurocodes. Building structures under consideration have been divided into structures designed to resist mining influences and existing structures, not adapted to conform to these influences at the design and erection stages

Full text: Brazil has the 6th largest global geological reserve of uranium, with the main reserve in Santa Quiteria - CE still not under exploration. Currently, uranium mining and processing in Brazil only occur near to the city of Caetite - BA. Several Non-Governmental Organizations claim that uranium mining in this region is polluting and may jeopardize the human health and safety and the environment. However, those in charge of the complex extraction and production of 'yellow cake' for generating fuel to the nuclear power plants reject these allegations. U-238 may be deposited in the skeleton by replacing the calcium, thus it is possible to estimate its incorporation by determining its concentration in the teeth. This study aimed to identify potential problems caused by mining to the population of Caetite, analyzing U-238 contained in samples of teeth extracted for orthodontic reasons from Caetite residents. The concentration of thorium and potassium incorporated were also determined by ICP-MS, as well the cumulative dose of radiation received by this population was estimated. For comparison sake, the same analysis was performed in samples from Santa Quiteria and Aracaju - SE (used as a control area). The doses estimated were compared to doses obtained with EPR spectra of the same samples. The accumulated amount of radioisotopes in the teeth of the population of Caetite is probably due to natural origin, thus it is not possible to state that the mining process in Caetite increases pollution or radiation exposure in a meaningful way.

Sandia National Laboratories (Sandia) has a long history in developing compact, mobile, very high-speed drilling systems and this technology could be applied to increasing the rate at which boreholes are drilled during a mine accident response. The present study reviews current technical approaches, primarily based on technology developed under other programs, analyzes mine rescue specific requirements to develop a conceptual mine rescue drilling approach, and finally, proposes development of a phased mine rescue drilling system (MRDS) that accomplishes (1) development of rapid drilling MRDS equipment; (2) structuring improved web communication through the Mine Safety & Health Administration (MSHA) web site; (3) development of an improved protocol for employment of existing drilling technology in emergencies; (4) deployment of advanced technologies to complement mine rescue drilling operations during emergency events; and (5) preliminary discussion of potential future technology development of specialized MRDS equipment. This phased approach allows for rapid fielding of a basic system for improved rescue drilling, with the ability to improve the system over time at a reasonable cost.

A Review of Extra-Terrestrial Mining Robot Concepts

Science.gov (United States)

Mueller, Robert P.; Van Susante, Paul J.

2011-01-01

Outer space contains a vast amount of resources that offer virtually unlimited wealth to the humans that can access and use them for commercial purposes. One of the key technologies for harvesting these resources is robotic mining of regolith, minerals, ices and metals. The harsh environment and vast distances create challenges that are handled best by robotic machines working in collaboration with human explorers. Humans will benefit from the resources that will be mined by robots. They will visit outposts and mining camps as required for exploration, commerce and scientific research, but a continuous presence is most likely to be provided by robotic mining machines that are remotely controlled by humans. There have been a variety of extra-terrestrial robotic mining concepts proposed over the last 100 years and this paper will attempt to summarize and review concepts in the public domain (government, industry and academia) to serve as an informational resource for future mining robot developers and operators. The challenges associated with these concepts will be discussed and feasibility will be assessed. Future needs associated with commercial efforts will also be investigated.

Geochemical characterisation of seepage and drainage water quality from two sulphide mine tailings impoundments: Acid mine drainage versus neutral mine drainage

Science.gov (United States)

Heikkinen, P.M.; Raisanen, M.L.; Johnson, R.H.

2009-01-01

Seepage water and drainage water geochemistry (pH, EC, O2, redox, alkalinity, dissolved cations and trace metals, major anions, total element concentrations) were studied at two active sulphide mine tailings impoundments in Finland (the Hitura Ni mine and Luikonlahti Cu mine/talc processing plant). The data were used to assess the factors influencing tailings seepage quality and to identify constraints for water treatment. Changes in seepage water quality after equilibration with atmospheric conditions were evaluated based on geochemical modelling. At Luikonlahti, annual and seasonal changes were also studied. Seepage quality was largely influenced by the tailings mineralogy, and the serpentine-rich, low sulphide Hitura tailings produced neutral mine drainage with high Ni. In contrast, drainage from the high sulphide, multi-metal tailings of Luikonlahti represented typical acid mine drainage with elevated contents of Zn, Ni, Cu, and Co. Other factors affecting the seepage quality included weathering of the tailings along the seepage flow path, process water input, local hydrological settings, and structural changes in the tailings impoundment. Geochemical modelling showed that pH increased and some heavy metals were adsorbed to Fe precipitates after net alkaline waters equilibrated with the atmosphere. In the net acidic waters, pH decreased and no adsorption occurred. A combination of aerobic and anaerobic treatments is proposed for Hitura seepages to decrease the sulphate and metal loading. For Luikonlahti, prolonged monitoring of the seepage quality is suggested instead of treatment, since the water quality is still adjusting to recent modifications to the tailings impoundment.

2018-02-01

Full Text Available Frequent subgraph mining (FSM plays an important role in graph mining, attracting a great deal of attention in many areas, such as bioinformatics, web data mining and social networks. In this paper, we propose SSiGraM (Spark based Single Graph Mining, a Spark based parallel frequent subgraph mining algorithm in a single large graph. Aiming to approach the two computational challenges of FSM, we conduct the subgraph extension and support evaluation parallel across all the distributed cluster worker nodes. In addition, we also employ a heuristic search strategy and three novel optimizations: load balancing, pre-search pruning and top-down pruning in the support evaluation process, which significantly improve the performance. Extensive experiments with four different real-world datasets demonstrate that the proposed algorithm outperforms the existing GraMi (Graph Mining algorithm by an order of magnitude for all datasets and can work with a lower support threshold.

Mining Product Data Models: A Case Study

2014-01-01

Full Text Available This paper presents two case studies used to prove the validity of some data-flow mining algorithms. We proposed the data-flow mining algorithms because most part of mining algorithms focuses on the control-flow perspective. First case study uses event logs generated by an ERP system (Navision after we set several trackers on the data elements needed in the process analyzed; while the second case study uses the event logs generated by YAWL system. We offered a general solution of data-flow model extraction from different data sources. In order to apply the data-flow mining algorithms the event logs must comply a certain format (using InputOutput extension. But to respect this format, a set of conversion tools is needed. We depicted the conversion tools used and how we got the data-flow models. Moreover, the data-flow model is compared to the control-flow model.

ERA`s Ranger uranium mine

Davies, W. [Energy Resources of Australia Ltd., Sydney, NSW (Australia)

1997-12-31

Energy Resource of Australia (ERA) is a public company with 68% of its shares owned by the Australian company North Limited. It is currently operating one major production centre - Ranger Mine which is 260 kilometres east of Darwin, extracting and selling uranium from the Ranger Mine in the Northern Territory to nuclear electricity utilities in Japan, South Korea, Europe and North America. The first drum of uranium oxide from Ranger was drummed in August 1981 and operations have continued since that time. ERA is also in the process of working towards obtaining approvals for the development of a second mine - Jabiluka which is located 20 kilometres north of Ranger. The leases of Ranger and Jabiluka adjoin. The Minister for the Environment has advised the Minister for Resources and Energy that there does not appear to be any environmental issue which would prevent the preferred Jabiluka proposal from proceeding. Consent for the development of ERA`s preferred option for the development of Jabiluka is being sought from the Aboriginal Traditional Owners. Ranger is currently the third largest producing uranium mine in the world producing 4,237 tonnes of U{sub 3}O{sub 8} in the year to June 1997.

The Smallest Valid Extension-Based Efficient, Rare Graph Pattern Mining, Considering Length-Decreasing Support Constraints and Symmetry Characteristics of Graphs

Directory of Open Access Journals (Sweden)

Unil Yun

2016-05-01

Full Text Available Frequent graph mining has been proposed to find interesting patterns (i.e., frequent sub-graphs from databases composed of graph transaction data, which can effectively express complex and large data in the real world. In addition, various applications for graph mining have been suggested. Traditional graph pattern mining methods use a single minimum support threshold factor in order to check whether or not mined patterns are interesting. However, it is not a sufficient factor that can consider valuable characteristics of graphs such as graph sizes and features of graph elements. That is, previous methods cannot consider such important characteristics in their mining operations since they only use a fixed minimum support threshold in the mining process. For this reason, in this paper, we propose a novel graph mining algorithm that can consider various multiple, minimum support constraints according to the types of graph elements and changeable minimum support conditions, depending on lengths of graph patterns. In addition, the proposed algorithm performs in mining operations more efficiently because it can minimize duplicated operations and computational overheads by considering symmetry features of graphs. Experimental results provided in this paper demonstrate that the proposed algorithm outperforms previous mining approaches in terms of pattern generation, runtime and memory usage.

Flora and vegetation on dumps of uranium mining in the southern part of the former GDR

Directory of Open Access Journals (Sweden)

Hartmut Sänger

2014-01-01

Full Text Available From 1946 to 1990 an intensive uranium mining had been carried out with underground mining and also with opencast mining by the Wismut enterprise in the southern part of the former GDR. The mining activity lead also in the surroundings of Ronneburg to a permanent growth of devastated areas, among others in the form of dumps and tailings. These areas form by reason of mining-specific contaminations, extrem biotops which demand high claims on the pioneer organisms during the phase of natural first settlement. From 1990 to 1992 vegetation mappings were carried out on 15 dumps of the Thuringia mining area according to Braun-Blanquet (1964. The utilization of the computer programm Flora _D (Frank and Klotz 1990 enabled the ecological characterisation of the dumps. On the 15 investigated dumps found were 498 higher plants, belonging to 65 families. One hundred species are species with a high dominance. The number of species per dump fluctuates between 1 I and 282. Pioneer plants occur on the berms mostly in the second year after stoppage of the dumping, on the slopes after five to ten years. After nearly ten years the first step of settlement seems to be finished. Among the mechanisms of spreading dominate wind- and burdock spread. According to the form of life forms the dump species are predominantly hemicryptophytes, further therophytes, geophytes and phanerophytes.

several studies are presently undertaken in the Walloon Region so as to assess the long term environmental impact caused by the shutting down of coal mines and their pumping operations. In many locations, new problems are encountered, such as sudden underground water appearance at hill slopes, coal heaps instability or flooding of underground cellars. Slope instability increase risks. The main goals of the presented studies are to suppress or at least to limit those risks and inconveniences and propose solutions to be implemented in the framework of the existing dewatering facilities built by the Walloon Region and local authorities in mines induced subsidence areas.

2016-01-01

Full Text Available The coal mine environment is complex and dangerous after gas accident; then a timely and effective rescue and relief work is necessary. Hence prediction of gas concentration in front of coal mine rescue robot is an important significance to ensure that the coal mine rescue robot carries out the exploration and search and rescue mission. In this paper, a gray neural network is proposed to predict the gas concentration 10 meters in front of the coal mine rescue robot based on the gas concentration, temperature, and wind speed of the current position and 1 meter in front. Subsequently the quantum genetic algorithm optimization gray neural network parameters of the gas concentration prediction method are proposed to get more accurate prediction of the gas concentration in the roadway. Experimental results show that a gray neural network optimized by the quantum genetic algorithm is more accurate for predicting the gas concentration. The overall prediction error is 9.12%, and the largest forecasting error is 11.36%; compared with gray neural network, the gas concentration prediction error increases by 55.23%. This means that the proposed method can better allow the coal mine rescue robot to accurately predict the gas concentration in the coal mine roadway.

Assessment of human and ecological risks from uranium and gold mining activities

International Nuclear Information System (INIS)

Hart, D.; McKee, P.; Garisto, N.

1995-01-01

Forecasting of ecological and human health risk has been widely used in the uranium mining industry to support decisions regarding acceptability of proposed mine developments and mine closure plans. Probabilistic assessment has been less frequently used in other mining sectors where radiological issues are less prominent, but is now beginning to be more broadly applied. Case studies are presented to illustrate probabilistic approaches in opening and closing assessments of uranium and gold mines. Risks to man and biota from operational emissions (radionuclides, arsenic, cyanide) and risk reductions following mine closure are forecast using probabilistic models of chemical fate, transport and exposure. These forecasts permit selection of operational and closure alternatives which produce acceptably low risks

Full Text Available High-utility itemset mining (HUIM is a critical issue in recent years since it can be used to reveal the profitable products by considering both the quantity and profit factors instead of frequent itemset mining (FIM of association rules (ARs. In this paper, an evolutionary algorithm is presented to efficiently mine high-utility itemsets (HUIs based on the binary particle swarm optimization. A maximal pattern (MP-tree strcutrue is further designed to solve the combinational problem in the evolution process. Substantial experiments on real-life datasets show that the proposed binary PSO-based algorithm has better results compared to the state-of-the-art GA-based algorithm.

Feasibility study of a self-remediation system for mine drainage using its thermal energy

Science.gov (United States)

Oh, Chamteut; Cheong, Youngwook; Yim, Giljae; Ji, Sangwoo

2016-04-01

Mine drainage is defined as the water which is discharged to the ground surface through shafts and/or cracks formed by mining activities. Typically, mine drainage features high concentration of acidity and metals since it passes through the underground. Therefore, for the purpose of protecting the surrounding natural environment, mine drainage should be remediated before being discharged to nature. Mine drainage, due to its nature of being retained underground, shows constant temperature which is independent from the temperature of the atmosphere above ground. This condition allows mine drainage to become a promising renewable energy source since energy can be recovered from water with constant temperature. In this research, a self-remediation system is proposed which remediates the mine drainage through electrochemical reactions powered by the thermal energy of mine drainage. High energy efficiency is able to be achieved by shortening the distance between the energy source and consumption, and therefore, this system has a strong advantage to be actualized. A feasibility study for the system was conducted in this research where the thermal energy of mine drainage over time and depth was calculated as energy supply and the required electrical energy for remediating the mine drainage was measured as energy consumption. While the technology of converting thermal energy directly into electrical energy is yet to be developed, energy balance analysis results showed that the proposed self-remediation system is theoretically possible.

Integrating Industrial Ecology Thinking into the Management of Mining Waste

Directory of Open Access Journals (Sweden)

Éléonore Lèbre

2015-10-01

Full Text Available Mining legacies are often dominated by large waste facilities and their associated environmental impacts. The most serious environmental problem associated with mine waste is heavy metals and acid leakage through a phenomenon called acid mine drainage (AMD. Interestingly, the toxicity of this leakage is partly due to the presence of valuable metals in the waste stream as a result of a diversity of factors influencing mining operations. A more preventive and recovery-oriented approach to waste management, integrated into mine planning and operations, could be both economically attractive and environmentally beneficial since it would: mitigate environmental impacts related to mine waste disposal (and consequently reduce the remediation costs; and increase the resource recovery at the mine site level. The authors argue that eco-efficiency and resilience (and the resulting increase in a mine’s lifetime are both critical—yet overlooked—characteristics of sustainable mining operations. Based on these arguments, this paper proposes a framework to assist with identification of opportunities for improvement and to measure this improvement in terms of its contribution to a mine’s sustainability performance.

On-Site Radon Detection of Mining-induced Fractures from Overlying Strata to the Surface: A Case Study of the Baoshan Coal Mine in China

Directory of Open Access Journals (Sweden)

Wei Zhang

2014-12-01

Full Text Available Large-scale longwall mining of shallow coal seams may cause mining-induced fractures that can project completely through to the surface. This could lead to a series of mine safety and environmental issues, further deteriorating the already fragile ecological environment in the Western mining areas in China. Therefore, an accurate and effective understanding of the spatiotemporal evolution law of mining-induced fractures in overlying strata and its relationship to upper aquifers is critical. In this paper, the application of the geophysical-chemical properties of radon in mining engineering is explored as a potential solution to the shortcomings of existing surveying methods. A radioactive measurement method is proposed for the detection of the development of mining-induced fractures from overlying strata to the surface in the Baoshan Coal Mine (BCM. The on-site test indicated that the first weighting step is approximately 60 m, the average periodic weighting step is approximately 20 m, and the influence coverage of the advanced abutment pressure is approximately 30 m. The presented method could be used as an indirect technical support to increase the safety of coal mining by acting as a simple, fast, and reliable method of detecting mining-induced fractures in overlying strata.

Science.gov (United States)

Wong, C L; Mendoza, J; Henson, S J; Qi, Y; Lou, W; L'Abbé, M R

2014-08-01

Few studies have examined consumer acceptability or comprehension of cholesterol-lowering claims on food labels. Our objective was to assess consumer attitudes and understanding of cholesterol-lowering claims regarding plant sterols (PS) and oat fibre (OF). We conducted two studies on: (1) PS claims and (2) OF claims. Both studies involved a randomized mock-packaged experiment within an online survey administered to Canadian consumers. In the PS study (n=721), we tested three PS-related claims (disease risk reduction claim, function claim and nutrient content claim) and a 'tastes great' claim (control) on identical margarine containers. Similarly, in the OF study (n=710), we tested three claims related to OF and a 'taste great' claim on identical cereal boxes. In both studies, participants answered the same set of questions on attitudes and understanding of claims after seeing each mock package. All claims that mentioned either PS or OF resulted in more positive attitudes than the taste control claim (Pprofile. How consumers responded to the nutrition claims between the two studies was influenced by contextual factors such as familiarity with the functional food/component and the food product that carried the claim. Permitted nutrition claims are approved based on physiological evidence and are allowed on any food product as long as it meets the associated nutrient criteria. However, it is difficult to generalize attitudes and understanding of claims when they are so highly dependent on contextual factors.

Problems and Alternatives of Settlement Lagoons for Mine Water Treatment System

Science.gov (United States)

Lee, Dong-Kil

2015-04-01

A field test and computational flow analysis were conducted to identify the structural problems with existing settlement lagoons and to propose effective alternatives. When it comes to existing settlement lagoons without any specifically designed internal structure, mine water flows along a specific route while other regions remained stagnant. Such a flow pattern along a specific region causes a significant reduction in retention time as well as the ineffective use of the space in a settlement lagoon. When applying the modified settlement lagoon design proposed in this study, the flow distribution of mine drainage became uniform and the time taken for mine drainage to reach the outlet was improved by as much as 360 times and the exchange efficiency was significantly enhanced from 14.5% to 82.7%.

Fallah, Mina; Niakan Kalhori, Sharareh R

2017-10-01

Smartphones represent a promising technology for patient-centered healthcare. It is claimed that data mining techniques have improved mobile apps to address patients' needs at subgroup and individual levels. This study reviewed the current literature regarding data mining applications in patient-centered mobile-based information systems. We systematically searched PubMed, Scopus, and Web of Science for original studies reported from 2014 to 2016. After screening 226 records at the title/abstract level, the full texts of 92 relevant papers were retrieved and checked against inclusion criteria. Finally, 30 papers were included in this study and reviewed. Data mining techniques have been reported in development of mobile health apps for three main purposes: data analysis for follow-up and monitoring, early diagnosis and detection for screening purpose, classification/prediction of outcomes, and risk calculation (n = 27); data collection (n = 3); and provision of recommendations (n = 2). The most accurate and frequently applied data mining method was support vector machine; however, decision tree has shown superior performance to enhance mobile apps applied for patients' self-management. Embedded data-mining-based feature in mobile apps, such as case detection, prediction/classification, risk estimation, or collection of patient data, particularly during self-management, would save, apply, and analyze patient data during and after care. More intelligent methods, such as artificial neural networks, fuzzy logic, and genetic algorithms, and even the hybrid methods may result in more patients-centered recommendations, providing education, guidance, alerts, and awareness of personalized output.

Mine subsidence control projects associated with solid waste disposal facilities

International Nuclear Information System (INIS)

Wood, R.M.

1994-01-01

Pennsylvania environmental regulations require applicant's for solid waste disposal permits to provide information regarding the extent of deep mining under the proposed site, evaluations of the maximum subsidence potential, and designs of measures to mitigate potential subsidence impact on the facility. This paper presents three case histories of deep mine subsidence control projects at solid waste disposal facilities. Each case history presents site specific mine grouting project data summaries which include evaluations of the subsurface conditions from drilling, mine void volume calculations, grout mix designs, grouting procedures and techniques, as well as grout coverage and extent of mine void filling evaluations. The case studies described utilized basic gravity grouting techniques to fill the mine voids and fractured strata over the collapsed portions of the deep mines. Grout mixtures were designed to achieve compressive strengths suitable for preventing future mine subsidence while maintaining high flow characteristics to penetrate fractured strata. Verification drilling and coring was performed in the grouted areas to determine the extent of grout coverage and obtain samples of the in-place grout for compression testing. The case histories presented in this report demonstrate an efficient and cost effective technique for mine subsidence control projects

2007-06-15

A three-layer model for digital communication in a mine is proposed. Two basic platforms are discussed: a uniform transmission network and a uniform data warehouse. An actual, ControlNet based, transmission network platform suitable for the Jining No.3 coal mine in China is presented. This network is an information superhighway intended to integrate all existing and new automation subsystems. Its standard interface can be used with future subsystems. The network, data structure and management decision-making all employ this uniform hardware and software. This effectively avoids the problems of system and information islands seen in traditional mine-automation systems. The construction of the network provides a stable foundation for digital communication in the Jining No.3 coal mine. 9 refs., 5 figs.

Mining is one of the most important industrial activities globally; however, mining processes have critical environmental impacts, as mining is a major source of metals and metalloids that contribute significantly to the pollution of soil, sediment, water and air. Heavy metals can impact the health of exposed human populations and nonhuman receptors. This study focused on arsenic because its genotoxicity is well-known. Previously, we proposed a methodology to evaluate and integrate risk from a single source affecting different biologic receptors. Here, we propose an alternative approach estimating arsenic exposure in children and kangaroo rats using probabilistic simulation with Monte Carlo modeling. The estimates are then associated to measured DNA damage and compared to both populations of children and rodents living in contaminated and in reference areas. Finally, based on the integrated analysis of the generated information, we evaluate the potential use of wild rodents (Dipodomys merriami) as a biomonitor at mining sites. Results indicate that the variation of genotoxicity in children of the reference site is approximately 2 units when compared to the children of the contaminated site. In the rodents we observed a variation of approximately 4 units between those of the reference site when compared to those living on the contaminated site. We propose that D. merriami can be used as a biomonitor organism in sites with mining activity, and that a non-lethal test can be used to evaluate risk from metal exposure.

2013-05-01

To assess patterns of injury and liability associated with operating room (OR) fires, closed malpractice claims in the American Society of Anesthesiologists Closed Claims Database since 1985 were reviewed. All claims related to fires in the OR were compared with nonfire-related surgical anesthesia claims. An analysis of fire-related claims was performed to identify causative factors. There were 103 OR fire claims (1.9% of 5,297 surgical claims). Electrocautery was the ignition source in 90% of fire claims. OR fire claims more frequently involved older outpatients compared with other surgical anesthesia claims (P fire claims (P fires (n = 93) increased over time (P fires occurred during head, neck, or upper chest procedures (high-fire-risk procedures). Oxygen served as the oxidizer in 95% of electrocautery-induced OR fires (84% with open delivery system). Most electrocautery-induced fires (n = 75, 81%) occurred during monitored anesthesia care. Oxygen was administered via an open delivery system in all high-risk procedures during monitored anesthesia care. In contrast, alcohol-containing prep solutions and volatile compounds were present in only 15% of OR fires during monitored anesthesia care. Electrocautery-induced fires during monitored anesthesia care were the most common cause of OR fires claims. Recognition of the fire triad (oxidizer, fuel, and ignition source), particularly the critical role of supplemental oxygen by an open delivery system during use of the electrocautery, is crucial to prevent OR fires. Continuing education and communication among OR personnel along with fire prevention protocols in high-fire-risk procedures may reduce the occurrence of OR fires.

An Efficient Approach to Mining Maximal Contiguous Frequent Patterns from Large DNA Sequence Databases

Directory of Open Access Journals (Sweden)

Md. Rezaul Karim

2012-03-01

Full Text Available Mining interesting patterns from DNA sequences is one of the most challenging tasks in bioinformatics and computational biology. Maximal contiguous frequent patterns are preferable for expressing the function and structure of DNA sequences and hence can capture the common data characteristics among related sequences. Biologists are interested in finding frequent orderly arrangements of motifs that are responsible for similar expression of a group of genes. In order to reduce mining time and complexity, however, most existing sequence mining algorithms either focus on finding short DNA sequences or require explicit specification of sequence lengths in advance. The challenge is to find longer sequences without specifying sequence lengths in advance. In this paper, we propose an efficient approach to mining maximal contiguous frequent patterns from large DNA sequence datasets. The experimental results show that our proposed approach is memory-efficient and mines maximal contiguous frequent patterns within a reasonable time.

2014-01-01

Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constitution of the backfill system, and the backfill process. Specific implementation of this technology and its application are analyzed for paste backfill mining in Daizhuang Coal Mine; a practical implementation shows that paste backfill mining can improve the safety and excavation rate of coal mining, which can effectively resolve surface subsidence problems caused by underground mining activities, by utilizing solid waste such as coal gangues as a resource. Therefore, paste backfill mining is an effective clean coal mining technology, which has widespread application. PMID:25258737

Automatic target validation based on neuroscientific literature mining for tractography

Directory of Open Access Journals (Sweden)

Xavier eVasques

2015-05-01

Full Text Available Target identification for tractography studies requires solid anatomical knowledge validated by an extensive literature review across species for each seed structure to be studied. Manual literature review to identify targets for a given seed region is tedious and potentially subjective. Therefore, complementary approaches would be useful. We propose to use text-mining models to automatically suggest potential targets from the neuroscientific literature, full-text articles and abstracts, so that they can be used for anatomical connection studies and more specifically for tractography. We applied text-mining models to three structures: two well studied structures, since validated deep brain stimulation targets, the internal globus pallidus and the subthalamic nucleus and, the nucleus accumbens, an exploratory target for treating psychiatric disorders. We performed a systematic review of the literature to document the projections of the three selected structures and compared it with the targets proposed by text-mining models, both in rat and primate (including human. We ran probabilistic tractography on the nucleus accumbens and compared the output with the results of the text-mining models and literature review. Overall, text-mining the literature could find three times as many targets as two man-weeks of curation could. The overall efficiency of the text-mining against literature review in our study was 98% recall (at 36% precision, meaning that over all the targets for the three selected seeds, only one target has been missed by text-mining. We demonstrate that connectivity for a structure of interest can be extracted from a very large amount of publications and abstracts. We believe this tool will be useful in helping the neuroscience community to facilitate connectivity studies of particular brain regions. The text mining tools used for the study are part of the HBP Neuroinformatics Platform, publicly available at http://connectivity-brainer.rhcloud.com/.

Locating previously unknown patterns in data-mining results: a dual data- and knowledge-mining method

Directory of Open Access Journals (Sweden)

Knaus William A

2006-03-01

Full Text Available Abstract Background Data mining can be utilized to automate analysis of substantial amounts of data produced in many organizations. However, data mining produces large numbers of rules and patterns, many of which are not useful. Existing methods for pruning uninteresting patterns have only begun to automate the knowledge acquisition step (which is required for subjective measures of interestingness, hence leaving a serious bottleneck. In this paper we propose a method for automatically acquiring knowledge to shorten the pattern list by locating the novel and interesting ones. Methods The dual-mining method is based on automatically comparing the strength of patterns mined from a database with the strength of equivalent patterns mined from a relevant knowledgebase. When these two estimates of pattern strength do not match, a high "surprise score" is assigned to the pattern, identifying the pattern as potentially interesting. The surprise score captures the degree of novelty or interestingness of the mined pattern. In addition, we show how to compute p values for each surprise score, thus filtering out noise and attaching statistical significance. Results We have implemented the dual-mining method using scripts written in Perl and R. We applied the method to a large patient database and a biomedical literature citation knowledgebase. The system estimated association scores for 50,000 patterns, composed of disease entities and lab results, by querying the database and the knowledgebase. It then computed the surprise scores by comparing the pairs of association scores. Finally, the system estimated statistical significance of the scores. Conclusion The dual-mining method eliminates more than 90% of patterns with strong associations, thus identifying them as uninteresting. We found that the pruning of patterns using the surprise score matched the biomedical evidence in the 100 cases that were examined by hand. The method automates the acquisition of

Nonparametric Fine Tuning of Mixtures: Application to Non-Life Insurance Claims Distribution Estimation

Science.gov (United States)

Sardet, Laure; Patilea, Valentin

When pricing a specific insurance premium, actuary needs to evaluate the claims cost distribution for the warranty. Traditional actuarial methods use parametric specifications to model claims distribution, like lognormal, Weibull and Pareto laws. Mixtures of such distributions allow to improve the flexibility of the parametric approach and seem to be quite well-adapted to capture the skewness, the long tails as well as the unobserved heterogeneity among the claims. In this paper, instead of looking for a finely tuned mixture with many components, we choose a parsimonious mixture modeling, typically a two or three-component mixture. Next, we use the mixture cumulative distribution function (CDF) to transform data into the unit interval where we apply a beta-kernel smoothing procedure. A bandwidth rule adapted to our methodology is proposed. Finally, the beta-kernel density estimate is back-transformed to recover an estimate of the original claims density. The beta-kernel smoothing provides an automatic fine-tuning of the parsimonious mixture and thus avoids inference in more complex mixture models with many parameters. We investigate the empirical performance of the new method in the estimation of the quantiles with simulated nonnegative data and the quantiles of the individual claims distribution in a non-life insurance application.

Two social impact assessment (SIA) studies of Central Queensland's Coppabella coal mine were undertaken in 2002-2003 and 2006-2007. As ex post studies of actual change, these provide a reference point for predictive assessments of proposed resource extraction projects at other sites, while the longitudinal element added by the second study illustrates how impacts associated with one mine may vary over time due to changing economic and social conditions. It was found that the traditional coupling of local economic vitality and community development to the life cycle of resource projects - the resource community cycle - was mediated by labour recruitment and social infrastructure policies that reduced the emphasis on localised employment and investment strategies. and by the cumulative impacts of multiple mining projects within relative proximity to each other. The resource community cycle was accelerated and local communities forced to consider ways of attracting secondary investment and/or alternative industries early in the operational life of the Coppabella mine in order to secure significant economic benefits and to guard against the erosion of social capital and the ability to cope with future downturns in the mining sector.

The mine and the furnace: Francis Bacon, Thomas Russell, and early Stuart mining culture.

Science.gov (United States)

Pastorino, Cesare

2009-01-01

Notwithstanding Francis Bacon's praise for the philosophical role of the mechanical arts, historians have often downplayed Bacon's connections with actual artisans and entrepreneurs. Addressing the specific context of mining culture, this study proposes a rather different picture. The analysis of a famous mining metaphor in The Advancement of Learning shows us how Bacon's project of reform of knowledge could find an apt correspondence in civic and entrepreneurial values of his time. Also, Bacon had interesting and so far unexplored links with the early modern English mining enterprises, like the Company of Mineral and Battery Works, ofwhich he was a shareholder. Moreover, Bacon's notes in a private notebook, Commentarius Solutus, and records of patents of invention, allow us to start grasping Bacon's connections with the metallurgist and entrepreneur Thomas Russell. Lastly, this paper argues that, to fully understand Bacon's links with the world of Stuart technicians and entrepreneurs, it is necessary to consider a different and insufficiently studied aspect of Bacon's interests, namely his work as patents referee while a Commissioner of Suits.

Mining and sustainable development: Considerations for minerals supply

International Nuclear Information System (INIS)

Lambert, Ian B.

2001-01-01

Sustainable development involves meeting the needs of human societies while maintaining viable biological and physical Earth systems. The needs include minerals: metals, fuels, industrial and construction materials. There will continue to be considerable demand for virgin mineral resources, even if levels of recycling and efficiency of use are optimal, and rates of population growth and globalisation decrease significantly. This article aims to stimulate debate on strategic issues for minerals supply. While the world has considerable stocks of mineral resources overall, international considerations of the environmental and social aspects of sustainable development are beginning to result in limitations on where mining will be conducted and what types of deposits will be mined. Current and emerging trends favour large mines in parts of the world where mining can be conducted within acceptable limits of environmental and social impact. Finding new deposits that meet such criteria will be all the more challenging given a disturbing global decline in the rate of discovery of major economic resources over the last decade, and the decreasing land area available for exploration and mining. To attract responsible exploration and mining, governments and mining nations will need to provide: regional-scale geo-scientific datasets as required to attract and guide future generations of exploration; resource access through multiple and sequential land use regimes, and frameworks for dealing with indigenous peoples' issues; and arrangements for consideration of mining proposals and regulation of mines that ensure responsible management of environmental and social issues. The minerals industry will need to continue to pursue advances in technologies for exploration, mining, processing, waste management and rehabilitation, and in public reporting of environmental and social performance.

A New Challenge for Information Mining

Directory of Open Access Journals (Sweden)

Roberto Paiano

2017-07-01

Full Text Available In the field of "Data Exploration" many approaches have been developed to solve the problem of management of big data that are also semantically rich. Nowadays, there is a strong need to support the discovery-oriented applications where data discovery is a highly ad hoc interactive process to support the users by assisting the navigation in the data to find interesting objects. In this work starting by a theoretical data exploration system, where we identified the main features that a data exploration system must have to an efficient exploratory experience, we propose a combination of two data exploration techniques faceted navigation and data mining with the aim to improve the discovery information during exploration. This approach is contextualized better in Information Mining. Information mining, in fact, aims at discovering knowledge, i.e. more general patterns within objects or collections of objects.

Survey of malpractice claims in dermatology

Altman, J.

1975-01-01

A statistical survey of malpractice claims asserted against dermatologists was made. The subject matter of the claims was divided into eight major categories: drug reactions, x-ray burns, poor cosmetic result following surgery, poor cosmetic result following medication, failure to diagnose cancer, improper diagnosis, infection from treatment, and miscellaneous. The study showed that a group of ''serious'' damage cases, which accounted for 34 percent of total claims, generated 94 percent of total dollar losses. The problem areas for malpractice claims appeared to be drug reactions, cosmetic chemosurgery, and failure to diagnose cancer. (U.S.)

Preference Mining Using Neighborhood Rough Set Model on Two Universes.

Science.gov (United States)

Zeng, Kai

2016-01-01

Preference mining plays an important role in e-commerce and video websites for enhancing user satisfaction and loyalty. Some classical methods are not available for the cold-start problem when the user or the item is new. In this paper, we propose a new model, called parametric neighborhood rough set on two universes (NRSTU), to describe the user and item data structures. Furthermore, the neighborhood lower approximation operator is used for defining the preference rules. Then, we provide the means for recommending items to users by using these rules. Finally, we give an experimental example to show the details of NRSTU-based preference mining for cold-start problem. The parameters of the model are also discussed. The experimental results show that the proposed method presents an effective solution for preference mining. In particular, NRSTU improves the recommendation accuracy by about 19% compared to the traditional method.

A New Method for Haul Road Design in Open-Pit Mines to Support Efficient Truck Haulage Operations

Directory of Open Access Journals (Sweden)

Jieun Baek

2017-07-01

Full Text Available The design of a haul road for an open-pit mine can significantly affect the cost associated with hauling ore and waste to the surface. This study proposes a new method for haul road design in open-pit mines to support efficient truck haulage operations. The road layout in open-pit mines was optimized by using raster-based least-cost path analysis, and the resulting zigzag road sections were simplified by applying the Douglas-Peucker algorithm. In addition, the road layout was modified by reflecting the radius of curvature suggested in the road design guides. Finally, a three-dimensional model reflecting the results of the road design was created by combining the road layout modification result with the slope of the open-pit mine and the bench design result. The application of the proposed method to an area containing gold deposits made it possible to design a haul road for open-pit mines such that it supported efficient truck haulage operations; furthermore, the time required for truck movement along the road could be estimated. The proposed method is expected to be useful for planning and designing open-pit mines and to facilitate the improvement of the road design function of existing mining software applications.

Verma, Dave K; Rajhans, Gyan S; Malik, Om P; des Tombe, Karen

2014-01-01

A comprehensive survey of respirable dust and respirable silica in Ontario gold mines was conducted by the Ontario Ministry of Labor during 1978-1979. The aim was to assess the feasibility of introducing gravimetric sampling to replace the assessment method which used konimeters, a device which gave results in terms of number of particles per cubic centimeter (ppcc) of air. The study involved both laboratory and field assessments. The field assessment involved measurement of airborne respirable dust and respirable silica at all eight operating gold mines of the time. This article describes the details of the field assessment. A total of 288 long-term (7-8 hr) personal respirable dust air samples were collected from seven occupational categories in eight gold mines. The respirable silica (α-quartz) was determined by x-ray diffraction method. The results show that during 1978-1979, the industry wide mean respirable dust was about 1 mg/m(3), and the mean respirable silica was 0.08 mg/m(3.)The mean% silica in respirable dust was 7.5%. The data set would be useful in future epidemiological and health studies, as well as in assessment of workers' compensation claims for occupational diseases such as silicosis, chronic obstructive pulmonary disease (COPD), and autoimmune diseases such as renal disease and rheumatoid arthritis.

2010-04-09

Some chiropractors and their associations claim that chiropractic is effective for conditions that lack sound supporting evidence or scientific rationale. This study therefore sought to determine the frequency of World Wide Web claims of chiropractors and their associations to treat, asthma, headache/migraine, infant colic, colic, ear infection/earache/otitis media, neck pain, whiplash (not supported by sound evidence), and lower back pain (supported by some evidence). A review of 200 chiropractor websites and 9 chiropractic associations' World Wide Web claims in Australia, Canada, New Zealand, the United Kingdom, and the United States was conducted between 1 October 2008 and 26 November 2008. The outcome measure was claims (either direct or indirect) regarding the eight reviewed conditions, made in the context of chiropractic treatment. We found evidence that 190 (95%) chiropractor websites made unsubstantiated claims regarding at least one of the conditions. When colic and infant colic data were collapsed into one heading, there was evidence that 76 (38%) chiropractor websites made unsubstantiated claims about all the conditions not supported by sound evidence. Fifty-six (28%) websites and 4 of the 9 (44%) associations made claims about lower back pain, whereas 179 (90%) websites and all 9 associations made unsubstantiated claims about headache/migraine. Unsubstantiated claims were made about asthma, ear infection/earache/otitis media, neck pain, The majority of chiropractors and their associations in the English-speaking world seem to make therapeutic claims that are not supported by sound evidence, whilst only 28% of chiropractor websites promote lower back pain, which is supported by some evidence. We suggest the ubiquity of the unsubstantiated claims constitutes an ethical and public health issue.

2011-05-01

Landscape planning and restoration in mine closure areas is not only an inevitable choice to sustain mining areas but also an important path to maximize landscape resources and to improve ecological function in mine closure areas. The analysis of the present mine development shows that many mines are unavoidably facing closures in China. This paper analyzes the periodic impact of mining activities on landscapes and then proposes planning concepts and principles. According to the landscape characteristics in mine closure areas, this paper classifies available landscape resources in mine closure areas into the landscape for restoration, for limited restoration and for protection, and then summarizes directions for their uses. This paper establishes the framework of spatial control planning and design of landscape elements from "macro control, medium allocation and micro optimization" for the purpose of managing and using this kind of special landscape resources. Finally, this paper applies the theories and methods to a case study in Wu'an from two aspects: the construction of a sustainable land-use pattern on a large scale and the optimized allocation of typical mine landscape resources on a small scale.

Improving occupational safety in Kuzbass mines

Energy Technology Data Exchange (ETDEWEB)

Evseev, V S

1986-08-01

Some achievements of VostNII are listed in improving occupational safety in Kuzbass mines. Methane is a major problem: 90.6% of mines is in category III or supercategory; over 21% has an absolute methane emission of 30 m/sup 3//min or more. Another problem is spontaneous fires, which cost 2 million t of coal per year. One method of preventing these is injection of antipyrogens (urea and diammonium phosphate); another is the creation of gel (water glass, ammonium chloride and water) barriers in goaf areas. High pressure water jets are also used. Various methods of improving ventilation systems to match increased coal output are proposed, including drilling large diameter ventilation boreholes from the surface. In Leninskugol' mines the useful air is only 55.8% of the total delivered. More attention should be given to degassing (currently producing 130 million m/sup 3//y of methane). Dust levels are increasing due to the advent of narrow web cutter loaders (100% of coal cutter loaders in Kuzbass mines in 1984). Water injection and spraying are partially effective at dust suppression. Some electrical safety devices developed by VostNII are described.

An application of discrete mathematics in the design of an open pit mine

Energy Technology Data Exchange (ETDEWEB)

Caccetta, L.; Giannini, L.M.

1988-09-01

The determination of the 'optimum pit limit' of a mine is considered to be a fundamental problem in mine planning as it provides information which is essential in the evaluation of the economic potential of a mineral deposit, and in the formulation of long-, intermediate-, and short-range mine plans. A number of mathematical techniques have been proposed to solve this problem, some of the more elaborate ones posing considerable computational problems. In this paper we discuss the development and implementation of a graph-theoretic technique originally proposed by Lerchs and Grossman. Our implementation strategy involves the use of a dynamic programming technique to 'bound' the optimum. 19 refs., 4 figs.

Septic arthritis (SA) cases can result in claims or litigation because of poor prognosis even if it is unavoidable. Although these claims or litigation are useful for understanding causes and background factors of medical errors, the characteristics of malpractice claims associated with SA remain undetermined in Japan. This study aimed to increase our understanding of malpractice claims in the clinical management of SA. We analyzed 6 civil precedents and 16 closed claims of SA from 8530 malpractice claims processed between July 2004 and June 2014 by the Tokyo office of Sompo Japan Nipponkoa Insurance, Incorporated. We also studied 5 accident and 21 incident reports of SA based on project data compiled by the Japan Council for Quality Health Care. The rate of negligence was 83.3% in the precedents and 75.0% in closed claims. Two main malpractice claim patterns were revealed: SA in a lower extremity joint following sepsis caused by methicillin-resistant Staphylococcus aureus in newborns and SA in an injection site following joint injection. These two patterns accounted for 83.3% and 56.3% of judicial cases and closed claim cases, respectively. Breakdowns in care process of accident and incident reports were clearly differentiated from judicial cases or closed claim cases (Fisher's exact test, p < 0.001). It is important to pay particular attention to SA following sepsis in newborns and to monitor for any signs of SA after joint injection to ensure early diagnosis. Analysis of both malpractice claims and accident and incident reports is essential to ensure a full understanding of the situation in Japan. Copyright © 2017. Published by Elsevier Taiwan LLC.

Text mining services are rapidly becoming a crucial component of various knowledge management pipelines, for example in the process of database curation, or for exploration and enrichment of biomedical data within the pharmaceutical industry. Traditional architectures, based on monolithic applications, do not offer sufficient flexibility for a wide range of use case scenarios, and therefore open architectures, as provided by web services, are attracting increased interest. We present an approach towards providing advanced text mining capabilities through web services, using a recently proposed standard for textual data interchange (BioC). The web services leverage a state-of-the-art platform for text mining (OntoGene) which has been tested in several community-organized evaluation challenges,with top ranked results in several of them.

In the fields of data mining and control, the huge amount of unstructured data and the presence of uncertainty in system descriptions have always been critical issues. The book Randomized Algorithms in Automatic Control and Data Mining introduces the readers to the fundamentals of randomized algorithm applications in data mining (especially clustering) and in automatic control synthesis. The methods proposed in this book guarantee that the computational complexity of classical algorithms and the conservativeness of standard robust control techniques will be reduced. It is shown that when a problem requires "brute force" in selecting among options, algorithms based on random selection of alternatives offer good results with certain probability for a restricted time and significantly reduce the volume of operations.

Food packages were objectively assessed to explore differences in nutrition labelling, selected promotional marketing techniques and health and nutrition claims between countries, in comparison to national regulations. Cross-sectional. Chip and sweet biscuit packages were collected from sixteen countries at different levels of economic development in the EPOCH (Environmental Profile of a Community's Health) study between 2008 and 2010. Seven hundred and thirty-seven food packages were systematically evaluated for nutrition labelling, selected promotional marketing techniques relevant to nutrition and health, and health and nutrition claims. We compared pack labelling in countries with labelling regulations, with voluntary regulations and no regulations. Overall 86 % of the packages had nutrition labels, 30 % had health or nutrition claims and 87 % displayed selected marketing techniques. On average, each package displayed two marketing techniques and one health or nutrition claim. In countries with mandatory nutrition labelling a greater proportion of packages displayed nutrition labels, had more of the seven required nutrients present, more total nutrients listed and higher readability compared with those with voluntary or no regulations. Countries with no health or nutrition claim regulations had fewer claims per package compared with countries with regulations. Nutrition label regulations were associated with increased prevalence and quality of nutrition labels. Health and nutrition claim regulations were unexpectedly associated with increased use of claims, suggesting that current regulations may not have the desired effect of protecting consumers. Of concern, lack of regulation was associated with increased promotional marketing techniques directed at children and misleadingly promoting broad concepts of health.

Knowledge-Based Reinforcement Learning for Data Mining

Science.gov (United States)

Kudenko, Daniel; Grzes, Marek

experts have developed heuristics that help them in planning and scheduling resources in their work place. However, this domain knowledge is often rough and incomplete. When the domain knowledge is used directly by an automated expert system, the solutions are often sub-optimal, due to the incompleteness of the knowledge, the uncertainty of environments, and the possibility to encounter unexpected situations. RL, on the other hand, can overcome the weaknesses of the heuristic domain knowledge and produce optimal solutions. In the talk we propose two techniques, which represent first steps in the area of knowledge-based RL (KBRL). The first technique [1] uses high-level STRIPS operator knowledge in reward shaping to focus the search for the optimal policy. Empirical results show that the plan-based reward shaping approach outperforms other RL techniques, including alternative manual and MDP-based reward shaping when it is used in its basic form. We showed that MDP-based reward shaping may fail and successful experiments with STRIPS-based shaping suggest modifications which can overcome encountered problems. The STRIPSbased method we propose allows expressing the same domain knowledge in a different way and the domain expert can choose whether to define an MDP or STRIPS planning task. We also evaluated the robustness of the proposed STRIPS-based technique to errors in the plan knowledge. In case that STRIPS knowledge is not available, we propose a second technique [2] that shapes the reward with hierarchical tile coding. Where the Q-function is represented with low-level tile coding, a V-function with coarser tile coding can be learned in parallel and used to approximate the potential for ground states. In the context of data mining, our KBRL approaches can also be used for any data collection task where the acquisition of data may incur considerable cost. In addition, observing the data collection agent in specific scenarios may lead to new insights into optimal data

Confusion in regulating coal mine water pollution: Regulatory overlap in SMCRA and the CWA

Energy Technology Data Exchange (ETDEWEB)

NONE

1997-11-01

Whenever a government uses two major pieces of legislation to combat a single public enemy, complaints of over-regulation and questions of jurisdiction from the individuals and industries affected are inevitable. Acid mine drainage (AMD) is a harmful and elusive enemy which threatens the integrity of our nation`s waters. The threat it poses to our environment cannot be solved without the awesome power of government; however, a fair and consistent enforcement of these two acts is imperative. The mining industry`s push to exempt landowners from liability for the acid discharges from abandoned mines is questionable in light of the serious AMD problems from these sources. The burden imposed on landowners to take abatement measures under the CWA is far outweighed by the continuing threat of abandoned mine AMD. The state environmental authorities who must completely reclaim these abandoned mine lands must pursue the landowners and make them pay the costs. In order to accomplish this, the state SMCRA regulators must increase coordination with the EPA`s state counterparts. The deficit problem in the ANL trust fund likely to improve anytime soon. Since SMCRA prohibits holding landowners liable for reclamation costs, the only way the abandoned mine AMD problem can be effectively remedied is by state environmental authorities seeking sanctions under the probably correct in claiming that the current CWA laws governing in-stream impoundments are overly burdensome. The EPA`s interest in protecting the quality of industrial impoundments that have no meaningful wetlands or recreational use seems to serve no rational purpose, especially in light of the onerous burden it places on coal operators attempting to comply with the CWA.

Fuzzy OLAP association rules mining-based modular reinforcement learning approach for multiagent systems.

Science.gov (United States)

Kaya, Mehmet; Alhajj, Reda

2005-04-01

Multiagent systems and data mining have recently attracted considerable attention in the field of computing. Reinforcement learning is the most commonly used learning process for multiagent systems. However, it still has some drawbacks, including modeling other learning agents present in the domain as part of the state of the environment, and some states are experienced much less than others, or some state-action pairs are never visited during the learning phase. Further, before completing the learning process, an agent cannot exhibit a certain behavior in some states that may be experienced sufficiently. In this study, we propose a novel multiagent learning approach to handle these problems. Our approach is based on utilizing the mining process for modular cooperative learning systems. It incorporates fuzziness and online analytical processing (OLAP) based mining to effectively process the information reported by agents. First, we describe a fuzzy data cube OLAP architecture which facilitates effective storage and processing of the state information reported by agents. This way, the action of the other agent, not even in the visual environment. of the agent under consideration, can simply be predicted by extracting online association rules, a well-known data mining technique, from the constructed data cube. Second, we present a new action selection model, which is also based on association rules mining. Finally, we generalize not sufficiently experienced states, by mining multilevel association rules from the proposed fuzzy data cube. Experimental results obtained on two different versions of a well-known pursuit domain show the robustness and effectiveness of the proposed fuzzy OLAP mining based modular learning approach. Finally, we tested the scalability of the approach presented in this paper and compared it with our previous work on modular-fuzzy Q-learning and ordinary Q-learning.

2008-01-01

The environment influence of five abandoned uranium mines in Jiangsu province from 1950s to 1960s is introduced. By monitoring air absorbed dose rate of external exposure γ radiation, it is found that the pollution scope of No.1 abandoned uranium mine is the biggest in five abandoned uranium mines. The No. 2 and No. 3 mine areas has achieved the limit use after they were desposed. The radioactivity and the gamma nuclein in solid samples(slag, soil, silt) and liquid samples (the surface water, the well water)of No. 1 abandoned uranium mine were further analyzed and measured, the measured values are higher. The pollution of abandoned uranium mines still exists and diffuses after 30 years. According to the monitoring results and the analysis of pollution present situation, suggestions and measures are proposed for the pollution control. (authors)

2017-05-01

Purpose: To examine characteristics of medical malpractice claims involving radiation oncologists closed during a 10-year period. Methods and Materials: Malpractice claims filed against radiation oncologists from 2003 to 2012 collected by a nationwide liability insurance trade association were analyzed. Outcomes included the nature of claims and indemnity payments, including associated presenting diagnoses, procedures, alleged medical errors, and injury severity. We compared the likelihood of a claim resulting in payment in relation to injury severity categories (death as referent) using binomial logistic regression. Results: There were 362 closed claims involving radiation oncology, 102 (28%) of which were paid, resulting in $38 million in indemnity payments. The most common alleged errors included “improper performance” (38% of closed claims, 18% were paid; 29% [$11 million] of total indemnity), “errors in diagnosis” (25% of closed claims, 46% were paid; 44% [$17 million] of total indemnity), and “no medical misadventure” (14% of closed claims, 8% were paid; less than 1% [$148,000] of total indemnity). Another physician was named in 32% of claims, and consent issues/breach of contract were cited in 18%. Claims for injury resulting in death represented 39% of closed claims and 25% of total indemnity. “Improper performance” was the primary alleged error associated with injury resulting in death. Compared with claims involving death, major temporary injury (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.29-5.85, P=.009), significant permanent injury (OR 3.1, 95% CI 1.48-6.46, P=.003), and major permanent injury (OR 5.5, 95% CI 1.89-16.15, P=.002) had a higher likelihood of a claim resulting in indemnity payment. Conclusions: Improper performance was the most common alleged malpractice error. Claims involving significant or major injury were more likely to be paid than those involving death.

Geospatial technology perspectives for mining vis-a-vis sustainable forest ecosystems

Directory of Open Access Journals (Sweden)

Goparaju Laxmi

2017-06-01

Full Text Available Forests, the backbone of biogeochemical cycles and life supporting systems, are under severe pressure due to varied anthropogenic activities. Mining activities are one among the major reasons for forest destruction questioning the survivability and sustainability of flora and fauna existing in that area. Thus, monitoring and managing the impact of mining activities on natural resources at regular intervals is necessary to check the status of their depleted conditions, and to take up restoration and conservative measurements. Geospatial technology provides means to identify the impact of different mining operations on forest ecosystems and helps in proposing initiatives for safeguarding the forest environment. In this context, the present study highlights the problems related to mining in forest ecosystems and elucidates how geospatial technology can be employed at various stages of mining activities to achieve a sustainable forest ecosystem. The study collates information from various sources and highlights the role of geospatial technology in mining industries and reclamation process.

Environmental degradation associated with mining activities may seriously threaten the health of local people and the sustainable development of coal mining, which may need to be addressed by improved environmental evaluation system. Based on analyzing environmental pollution from coal mining and the increasing need for raw coal, this paper establishes an environmental evaluation system, covering environmental situation, resource protection and economic benefit, for sustainable development in coal mining. This paper proposes methods for calculating the weight of each index and the environmental sustainable capability taking into account the method of Analytic Hierarchy Process (AHP). Finally, the index system is used to evaluate the environmental sustainability of coal mining in the Qijiang area, Western China, which has demonstrated the validity of the index system. It may also be useful as a tool to assess the environmental impact of mining areas, as well as a measure to promote sustainable development in coal mining. (author)

Claims procedures for employee benefit plans--Pension and Welfare Benefits Administration, Department of Labor. Request for information.

Science.gov (United States)

1997-09-08

This document requests information from the public concerning the advisability of amending the existing regulation under the Employee Retirement Income Security Act of 1974 (ERISA) that establishes minimum requirements for employee benefit plan claims procedures. The term "claims procedure" refers to the process that employee benefit plans must provide for participants and beneficiaries who seek to obtain pension or welfare plan benefits, including requests for medical treatment or services, consideration of claims, and review of denials of claims by plans. The primary purpose of this notice is to obtain information to assist the Department of Labor (the Department) in evaluating (1) the extent to which the current claims procedure regulation assures that group health plan participants and beneficiaries are provided with effective and timely means to file and resolve claims for health care benefits, and (1) whether and in what way the existing minimum requirements should be amended with respect to group health plans covered by ERISA. The furnished information also will assist the Department in determining whether the regulation should be amended with respect to pension plans covered by ERISA and in developing legislative proposals to address any identified deficiencies relating to the claims procedures that cannot be addressed by amending the current regulation.

New Zealand mining legislation and recommendations for change following the Pike River disaster

International Nuclear Information System (INIS)

King, Tony

2012-01-01

There is good evidence that existing health and safety legislation in New Zealand (NZ) has produced a marked and sustained improvement in occupational health and in high-frequency low-consequence accidents.The same cannot be said for high-consequence low-frequency events. Changes to the regulatory framework should focus on these high- consequence low-frequency events although not to the detriment of low- consequence event safety. The (NZ) underground coal mining industry is characterised by a very small number of operating mines that are distinctly different from each other. This is also true of proposed mines, where there is even more variety in the type of firms proposing to operate these mines. The risks that each individual mine faces are varied and risks that predominate in one operation (for example methane or spontaneous combustion) may be entirely absent at another nearby operation. Research strongly suggests that the best regulatory approach for underground coal mines in NZ is process-based standards, supported by performance standards to identify issues and set appropriate performance outcomes. A well-resourced locally based inspectorate comprising knowledgeable and experienced inspectors with NZ mining experience is required, supported by access to overseas expertise. The Health and Safety in Employment Act 1992 should remain the governing legislation for NZ coal mining. The existing mining-specific regulations should be replaced for underground coal mining with a new set of regulations. These new regulations should draw heavily on the Queensland regulations with the best aspects of New South Wales and elsewhere also included. The internationalisation of management, advisors and workers supports an approach based on good overseas practice, rather than a highly- individualised, uniquely NZ solution. Learnings and recommendations from the Pike River Royal Commission should be incorporated into performance standards and outcomes in the new regulations.

Standardization and rearrangement is proposed for all the mining laws in the Federal Republic of Germany, especially of the regulations concerning prospecting and mining of natural resources. The draft provides; 1) creation of a modern, elastic system of concessions for particularly important natural resources withdrawn from the landed property; smoothing of the existing system of mineral rights; 2) development of the instruments of mining law adapted to the special requirements of mining natural resources in view of preventive and current control of the operation and its supervision; 3) first-time authorizations for federal safety and labor protection decrees; 4) reformation of the relationship with the employer's liability insurances and, resulting therefrom, improvement of the accident prevention measures; 5) stronger embodiment of damage-preventing measures in mining-damage law; improvement of the extent of liability and the protection of those damaged; 6) accounting for related new engineering developments (underground tankless storage); 7) final regulation for prospecting and mining of natural resources in the range of the continental shelf; 8) relief of mining law from alien legal matters as well as liquidation of antiquated institutes of mining law.

Fingerprinting Localization Method Based on TOA and Particle Filtering for Mines

Directory of Open Access Journals (Sweden)

Boming Song

2017-01-01

Full Text Available Accurate target localization technology plays a very important role in ensuring mine safety production and higher production efficiency. The localization accuracy of a mine localization system is influenced by many factors. The most significant factor is the non-line of sight (NLOS propagation error of the localization signal between the access point (AP and the target node (Tag. In order to improve positioning accuracy, the NLOS error must be suppressed by an optimization algorithm. However, the traditional optimization algorithms are complex and exhibit poor optimization performance. To solve this problem, this paper proposes a new method for mine time of arrival (TOA localization based on the idea of comprehensive optimization. The proposed method utilizes particle filtering to reduce the TOA data error, and the positioning results are further optimized with fingerprinting based on the Manhattan distance. This proposed method combines the advantages of particle filtering and fingerprinting localization. It reduces algorithm complexity and has better error suppression performance. The experimental results demonstrate that, as compared to the symmetric double-sided two-way ranging (SDS-TWR method or received signal strength indication (RSSI based fingerprinting method, the proposed method has a significantly improved localization performance, and the environment adaptability is enhanced.

2000-01-12

Welcome to this symposium which is part of the ongoing effort to prepare an Environmental Impact Statement (EIS) regarding mountaintop mining and valley fills. The EIS is being prepared by the U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, U.S. Office of Surface Mining, and U.S. Fish and Wildlife Service, in cooperation with the State of West Virginia. Aquatic Ecosystem Enhancement (AEE) at mountaintop mining sites is one of fourteen technical areas identified for study by the EIS Interagency Steering Committee. Three goals were identified in the AEE Work Plan: 1. Assess mining and reclamation practices to show how mining operations might be carried out in a way that minimizes adverse impacts to streams and other environmental resources and to local communities. Clarify economic and technical constraints and benefits. 2. Help citizens clarify choices by showing whether there are affordable ways to enhance existing mining, reclamation, mitigation processes and/or procedures. 3. Ide identify data needed to improve environmental evaluation and design of mining projects to protect the environment. Today’s symposium was proposed in the AEE Team Work Plans but coordinated planning for the event began September 15, 1999 when representatives from coal industry, environmental groups and government regulators met in Morgantown. The meeting participants worked with a facilitator from the Canaan Valley Institute to outline plans for the symposium. Several teams were formed to carry out the plans we outlined in the meeting.

Numerical Modeling Tools for the Prediction of Solution Migration Applicable to Mining Site

International Nuclear Information System (INIS)

Martell, M.; Vaughn, P.

1999-01-01

Mining has always had an important influence on cultures and traditions of communities around the globe and throughout history. Today, because mining legislation places heavy emphasis on environmental protection, there is great interest in having a comprehensive understanding of ancient mining and mining sites. Multi-disciplinary approaches (i.e., Pb isotopes as tracers) are being used to explore the distribution of metals in natural environments. Another successful approach is to model solution migration numerically. A proven method to simulate solution migration in natural rock salt has been applied to project through time for 10,000 years the system performance and solution concentrations surrounding a proposed nuclear waste repository. This capability is readily adaptable to simulate solution migration around mining

Coal mining and agriculture: a study in environmental impact assessment. [On agriculture in UK

Energy Technology Data Exchange (ETDEWEB)

Selman, P.H.

1986-03-01

Coal mining activities in the U.K. are reported to be extending into areas of comparatively unspoilt countryside. Despite reductions in the National Coal Board's programme of future expansion, it is considered that the scale of impact of new mining activities on agriculture is still likely to be significant. The major impact will be associated with land alienation, but a wide range of other adverse effects will also be encountered. In view of the controversy likely to accompany new mining proposals, it is recommended that methods of environmental impact assessment (EIA) should be adopted. The nature and components of EIA are reviewed, and a framework appropriate to mining-agriculture conflicts is advanced. This approach is more closely examined In relation to recent developments in Leicestershire, U.K. It is found that the magnitude of agricultural impact is small in national terms, but may be severe at the local and - if mining activities become geographically concentrated - even at the sub-regional level. Systematic scrutiny of major coaling proposals by EIA will therefore become essential. (115 refs.)

2013-04-01

Artificial neural network (ANN) with back propagation algorithm (BP) and ANFIS was chosen as an alternative technique in modeling motor insurance claims. In particular, an ANN and ANFIS technique is applied to model and forecast the Malaysian motor insurance data which is categorized into four claim types; third party property damage (TPPD), third party bodily injury (TPBI), own damage (OD) and theft. This study is to determine whether an ANN and ANFIS model is capable of accurately predicting motor insurance claim. There were changes made to the network structure as the number of input nodes, number of hidden nodes and pre-processing techniques are also examined and a cross-validation technique is used to improve the generalization ability of ANN and ANFIS models. Based on the empirical studies, the prediction performance of the ANN and ANFIS model is improved by using different number of input nodes and hidden nodes; and also various sizes of data. The experimental results reveal that the ANFIS model has outperformed the ANN model. Both models are capable of producing a reliable prediction for the Malaysian motor insurance claims and hence, the proposed method can be applied as an alternative to predict claim frequency and claim severity.

Lin, K J; Schneeweiss, S

2016-08-01

Health insurance claims and electronic health records (EHR) databases have been considered the preferred data sources with which to study drug safety and effectiveness in routine care. Linking claims data to EHR allows researchers to leverage the complementary advantages of each data source to enhance study validity. We propose a framework to evaluate the need for supplementing claims data with EHR and vice versa to optimize outcome ascertainment, exposure assessment, and confounding adjustment. © 2016 American Society for Clinical Pharmacology and Therapeutics.

A Framework for Assessing the Impacts of Mining Development on Regional Water Resources in Colombia

Directory of Open Access Journals (Sweden)

Neil McIntyre

2018-03-01

Full Text Available Developing its large-scale mining industry is an economic priority for Colombia. However, national capacity to assess and manage the water resource impacts of mining is currently limited. This includes lack of baseline data, lack of suitable hydrological models and lack of frameworks for evaluating risks. Furthermore, public opposition to large scale mining is high and is a barrier to many proposed new mining projects mainly because of concerns about impacts on water resources. There are also concerns about impacts on the uplands that are important water sources, particularly the páramo ecosystem. This paper argues the case for a new framework for Strategic Assessment of Regional Water Impacts of Mining, aiming to support land use planning decisions by government for selected mining and prospective mining regions. The proposed framework is modelled on the Australian Government’s Bioregional Assessments program, converted into seven stages plus supporting activities that meet the Colombian development context. The seven stages are: (1 Contextual information; (2 Scenario definition; (3 Risk scoping; (4 Model development; (5 Risk analysis; (6 Database development; and (7 Dissemination by government to stakeholders including the general public. It is emphasised that the process and results should be transparent, the data and models publicly accessible, and dissemination aimed at all levels of expertise.

MONITORING OF MINING

Full Text Available The way mining was monitored in the past depended on knowledge, interest and the existing legal regulations. Documentary evidence about this work can be found in archives, libraries and museums. In particular, there is the rich archival material (papers and books concerning the work of the one-time Imperial and Royal Mining Captaincies in Zagreb, Zadar, Klagenfurt and Split, A minor part of the documentation has not yet been transferred to Croatia. From mining handbooks and books we can also find out about mining in Croatia. In the context of Austro-Hungary. For example, we can find out that the first governorships in Zagreb and Zadar headed the Ban, Count Jelacic and Baron Mamula were also the top mining authorities, though this, probably from political motives, was suppressed in the guides and inventories or the Mining Captaincies. At the end of the 1850s, Croatia produced 92-94% of sea salt, up to 8.5% of sulphur, 19.5% of asphalt and 100% of oil for the Austro-Hungarian empire. From data about mining in the Split Mining Captaincy, prepared for the Philadephia Exhibition, it can be seen that in the exploratory mining operations in which there were 33,372 independent mines declared in 1925 they were looking mainly for bauxite (60,0%, then dark coal (19,0%, asphalts (10.3% and lignites (62%. In 1931, within the area covered by the same captaincy, of 74 declared mines, only 9 were working. There were five coal mines, three bauxite mines and one for asphalt. I suggest that within state institution, the Mining Captaincy or Authority be renewed, or that a Mining and Geological Authority be set ap, which would lead to the more complete affirmation of Croatian mining (the paper is published in Croatian.

Anchor-Free Localization Method for Mobile Targets in Coal Mine Wireless Sensor Networks

OpenAIRE

Pei, Zhongmin; Deng, Zhidong; Xu, Shuo; Xu, Xiao

2009-01-01

Severe natural conditions and complex terrain make it difficult to apply precise localization in underground mines. In this paper, an anchor-free localization method for mobile targets is proposed based on non-metric multi-dimensional scaling (Multi-dimensional Scaling: MDS) and rank sequence. Firstly, a coal mine wireless sensor network is constructed in underground mines based on the ZigBee technology. Then a non-metric MDS algorithm is imported to estimate the reference nodes’ location.

Ways of increasing safety in mining at the Berezovskii-1 surface mine

Energy Technology Data Exchange (ETDEWEB)

Kuznetsov, N N; Malyarenko, V I

1986-12-01

Methods are descrubed wgucg were developed to alleviate or prevent the effects of landslides in a Kansk-Achinsk surface mine. Such a landslide took place in 1983 at the Berezovskii-1 mine when 250 m of an excavation trench suffered a collapse involving 680,000 mT of materials. Surveys revealed large zones of flooded ground with high proportions of argillites and aleurolites which swell in the presence of water. To keep costs down, a method using gravity is proposed for safety of re-excavation work near spoil banks. In this method a pillar of rock is left at the base of the spoil bank, the edge of the slope of which is moved back from the trench. Hard rock is placed at the leading edge of the spoil bank. The stability factor of the trench side may be raised from 0.87 to 1.12, and this is accompanied by savings in labor and costs.

Highland Uranium Solution Mining Project. Draft environmental statement

International Nuclear Information System (INIS)

1978-05-01

Exxon Minerals Co. proposes to conduct production-scale solution mining (in situ leaching) of uranium within the existing Highland Operation area in Converse County, Wyoming. The project would result in the temporary removal of 200 acres from grazing and the actual disturbance of 50 acres. About 4500 acre-ft of water will be withdrawn from the ore zone aquifer over the 10-year life of the project. There will be no discharge of liquid effluents from the project; atmospheric effluents will be within acceptable limits. Radiation doses at the nearest ranch resulting from solution mining activities were estimated. The project proposes the production and utilization of 1 to 3 million lb of uranium resources. It will not produce any significant socioeconomic impact on the local area. Alternatives to the project were considered, and conditions for issuing the source material license are listed

  Based on standard option pricing arguments and assumptions (including no convenience yield and sustainable property rights), we will not observe operating gold mines. We find that asymmetric information on the reserves in the gold mine is a necessary and sufficient condition for the existence...... of operating gold mines. Asymmetric information on the reserves in the mine implies that, at a high enough price of gold, the manager of high type finds the extraction value of the company to be higher than the current market value of the non-operating gold mine. Due to this under valuation the maxim of market...

The mining methods at the Fraisse mine

International Nuclear Information System (INIS)

Heurley, P.; Vervialle, J.P.

1985-01-01

The Fraisse mine is one of the four underground mines of the La Crouzille mining divisions of Cogema. Faced with the necessity to mechanize its workings, this mine also had to satisfy a certain number of stringent demands. This has led to concept of four different mining methods for the four workings at present in active operation at this pit, which nevertheless preserve the basic ideas of the methods of top slicing under concrete slabs (TSS) or horizontal cut-and-fill stopes (CFS). An electric scooptram is utilized. With this type of vehicle the stringent demands for the introduction of means for fire fighting and prevention are reduced to a minimum. Finally, the dimensions of the vehicles and the operation of these methods result in a net-to-gross tonnages of close to 1, i.e. a maximum output, combined with a minimum of contamination [fr

New Advantage 24 contraceptive gel claims 24-hour effectiveness. But proposed FDA rule could put N-9 products to the test.

Science.gov (United States)

1995-04-01

Advantage 24 is a new contraceptive gel that makes use of bioadhesive technology to offer 24 hours of protection relying on the spermicide nonoxynol-9 (N-9) in lower concentrations. If a proposed US Food and Drug Administration (FDA) rule is enforced N-9 may be examined closely. The manufacturer, Whitehall-Robins Healthcare in New Jersey, stopped production of the Today contraceptive sponge because of the costs of complying with FDA standards. The Advantage 24 gel costs twice as much as the sponge. It is made in Switzerland and distributed by an Illinois company. Any vaginal contraceptive containing N-9 would be approved by the FDA as long as it complied with guidelines laid down in an FDA monograph. However, the registration of the gel could not be confirmed. The product uses a bioadhesive technology concept that natural substances adhere to epithelial and mucosal tissues in the body. Polycarbofil is mixed with water, N-9, and mineral oil to create an emulsion that allows for a time-release mechanism, but at any given time only 2 mg of N-9 is available to kill sperm. The final formula for Advantage 24 is 52.5 mg per dose. Too much N-9 can be toxic, as demonstrated by the Today sponge, which contained 1000 mg of N-9. In Kenya prostitutes using it frequently experienced 3 times as many genital lesions as those using a placebo. A study of Advantage 24 by a Miami laboratory involved 250 women, 22-45 years old, who had had prior tubal ligations. When the gel was applied 15-30 minutes before intercourse the efficacy rate was 98%; it was 91% for those applying it 12 hours before; and it was 86% when the gel was applied 24 hours ahead of time. FDA compliance officers are intrigued about the claim that the gel lasts 24 hours. However, if the claim is held up by research data, women will have an easily available, portable, efficient, aesthetic, and highly effective contraceptive.
