"This book contains high-quality papers from the principal mining research institutes of the USA, United Kingdom, India and South Africa, thus providing up-to-date coverage of underground mining and technology in the main mining areas of the world. The theme is mining in adverse conditions using state-of-the-art technology. A wide range of problems facing mining engineers is discussed, namely: thick seam working, mining under massive beds, highly productive room and pillar operations, water problems, ventilation, and electronics in longwall mining."@en . .
