The document discusses the benefits of mechanizing mining operations to improve safety standards and phase out manual loading. It provides statistics showing a reduction in accidents, especially those due to roof and side falls, after mechanization was introduced at mines operated by SCCL in India. Mechanization led to a 50% reduction in fatalities and allowed experienced workers to be redeployed to safer roles. However, additional safety precautions are needed to address new risks from increased electricity, moving machinery, and equipment maintenance.

13. Production Vs Mechanisation Though mining in M/s SCCL started with Hand Section, gradual shift over the years to mechanization in phased manner has reduced accidents, met higher demand of coal and resulted in coal conservation in mining thick coal seams by blasting gallery methods in conjunction with remotely operated Load Haul Dumpers (LHDs).
