Mine Accidents in Underground Coal Mines vis-a-vis Strata Control and Safety Management System

摘要

This paper presents an overview of problems of underground coal mining in India and the need of strata control investigations for improved safety, conservation and economy of the coal mining operations. Mine accidents due to strata control, Instrumentation required for better understanding of strata behaviour around underground opening is presented besides approaches for design of strata control techniques. In view of the significant level of accidents due to roof and side falls in Indian coal mines, emphasis is made on the recent trends in geotechnical investigations, and need of further studies into human behaviour and safety management systems. Purpose of geotechnical instrumentation for strata behaivour monitoring in coal mines and mining options in Indian coalfields is also discussed with reference to strata control problems. The broad drivers of behavior depending on training and organizational setup need further study and implementation of proper control measures in minimizing if not eliminating the chances of accidents in mines.
