This self-contained classic textbook on the subject of mine disasters and mine rescue draws on the author's nearly thirty years of teaching and research experience and his abiding interest in mine safety for the benefit of mining engineering students. It provides a comprehensive view of the hazards constantly posed by fires, explosions, coal and gas outbursts and inundations in mines and the various rescue equipment in use, including the recent ones. Combating the problem of acid mine drainage and the use of explosibility diagrams, including USBM, for predicting flammability of firegases are some of the significant additions to the third edition.
Besides mining engineering students, this book will also be of great value to practising mining engineers, safety enforcement agencies, and rescue organisations.
M A Ramlu was Head, Department of Mining Engineering at the Indian Institute of Technology Kharagpur for nearly twenty years. He was also Dean of Sponsored Research and Consultancy and Deputy Director and Acting Director of the same institute, from which he retired in 1987. He pioneered postgraduate courses, mining research and continuing education programmes at mining departments in the country. He had been a member of the Development of Mineral Resources & Technology Upgradation Fund of the Government of Andhra Pradesh and a member of the Technical Committee, AP Pollution Control Board, Government of Andhra Pradesh. His main interests are in the area of spontaneous combustion of coal, explosibility of coal dust, mine rescue apparatus and coal mine planning and mechanization.
