Abstract
Intensification and concentration of the mining works increases substantially the risk of geo- and gasdynamic effects arising within the coal mines. Herewith are presented the results of the analytic and experimental studies on stress-strain state of rock mass due to technogenic impact. Under such conditions a potential avalanche destruction of coal rock mass may occur. Some criteria for evaluation of gas-dynamic danger for rock mass, for active stopes and development faces are given. The computer-aided system for monitoring of hazard of gas- and geodynamic phenomena in mines is suggested.
