expectations" were the following subsections which form the main structure of the proceedings: ( 1) Ways of developing the mining industry in different countries. (2) Trends in new technology and equipment for the mining industry in the year 2000. (3) Improving management in mining operations and increasing economic returns. (4) Effect and prospects of computer applications in the mining industry. ( 5 ) Economic and market forecasting in the mining industry. The proceedings essentially contain 133 papers divided amongst these five broad subsection headings. Most of the papers deal with descriptions of particular mining operations in various countries, state-of-the-art reports, the introduction of new techniques and concepts into increasingly complex mining and geological settings, new approaches to mine management, the emergence of new strategies, recent trends in mine development, mineral resource conservation, reclamation and environmental matters, mining machinery developments, mine excavation technology, mine environmental aspects, geotechnical aspects, computers in mining, hazard monitoring, control systems, trends in surface mining and economic and marketing aspects. The proceedings include abstracts of the material presented in the poster sessions and are classified under: ( 1 ) Open pit mining, (2) Deep mining, (3) Computer applications and (4) Overview. The proceedings contain a wealth of information on mining for the future and includes up-to-date accounts of new mining developments particularly regarding technological trends in various countries. The papers are wide ranging in their treatment of important mining topics facing different mining industries in several countries. The proceedingsprovide an important reference source and are recommended for consultation by researchers, practitioners and educationalists with interests in the trends and expectations of mining for the future. Longwall thick seam mining, Edited by R.V. Ramani and A.K. Ghose. Oxford and I.B.H. Publishing Co. Pvt. Ltd., New Delhi, 256 pages of text, tables of data, diagrams and photographs. The volume represents the proceedings of an international conference on longwall mining systems for thick seam mining held at Dhanbad, January 1113, 1986. The book contains seventeen papers and five appendices. The paper cover a wide range of aspects associated with the mining of thick coal seams. The first paper deals with longwall production potential analysis by computerised methods, whilst the second and third are concerned with longwall
349 evolution for thick seam working in India and a review of alternatives to longwall mining respectively. The next three papers describe longwall mining projects in the U.S.A., namely at Carbon County, western U.S.A. and Utah. Papers seven, eight and nine address strata control aspects, support capacity and multi-slicing. There follows an interesting account of longwall coal mining demonstrations initiated by the U.S. Bureau of Mines with reference to York Canyon, Sunnyside, Old Ben Mine No. 24, Thompson Creek and Duch Creek No. 1 mines. Paper eleven discusses longwall mining at Singareni, India, whilst the following two papers also describe Indian philosophy and experience of longwall caving and working of thick coal seams. The remaining four papers examine ventilation considerations of gassy seams in Alabama, geochemical input data for longwall thick seam working, rockbursts in longwall mining and the modelling of thick seam working respectively. The five appendices give useful information on the conference discussion findings, US '86 census of longwall faces which gives a wealth of operational and equipment data, India '85 census of longwall faces, bibliography of U.S. longwall literature and a bibliography of Indian longwall literature. The book contains much useful information on the application of longwall mining to thick coal seams. The detailed accounts given refer to installations in the U.S.A. and India, together with supporting information on operational and control aspects and provides an important insight into the problems and solutions of applying the longwall mining technique to thick seam working. The book is strongly recommended to all with interests in longwall mining and particularly those engaged in thick seam extraction planning and subsequent operation. The roles played by strata control and geological factors are demonstrated to be especially important. The book is skillfully edited and well presented both as a working document and as a reference source. B.N. WHITTAKER (Nottingham,U.K.)
