Abstract
The development of drilling and blasting operations at mining enterprises is considered. Drilling and blasting parameters have been developed for explosive breaking of blocks in highly methane-bearing coal seams. It is found that coal combustion after explosions occurred with abundant methane release from 0.25 to 0.37 m3/h.
