Abstract
The authors validate efficiency and safety of mining under possible gas-and-dynamic phenomena by directing natural energy of rocks to breakage and based on preliminary coal degassing and implementation of resource-saving and resource-reproducing geotechnologies. Relevant recommendations are given. In addition, the authors present a procedure to forecast and control geomechanical processes, considering formation and expansion of mined-out void in borehole mining.
