The future of activity in Poland's lignite sector will be determined by the demand for this fuel, which will in turn result from mining possibilities and economic competitiveness of the fuel in relation to other sources of electrical energy. The paper discusses all these factors and presents a framework programme for the development of Poland's lignite sector until 2040 (in detail) and further ahead to 2075, called the 'Agreement of manufacturers of lignite'. 4 refs., 5 tabs.
Coal mining technologies possible for use in the Polish hard coal mining sector ensuring its sustainable development; Technologie eksploatacji wegla mozliwe do zastosowania w polskim gornictwie wegla kamiennego zapewniajace jego zrownowazony rozwoj

The paper presents a prediction of the developments in hard coal mining technologies both in Poland and in the world. The longwall and the room-and-pillar systems will be realised. In Poland longwall equipment must be made more reliable and be better monitored, and more use made of roof bolting and means of controlling methane and rockbursts. Methods of underground gasification of coal seams need further development to realise the potential of this resource at reasonable production cost and with minimal environmental impact. 38 refs., 6 figs., 4 tabs.
