Abstract

The calculations of stress state and failure of rock mass in the vicinity of longwall in a coal bed with the high gas content in Polysaevskaya Mine, SUEK-Kuzbass, are described. The effect of the mining depth and coalbed gas pressure on the geomechanical situation in the longwall is illustrated. The authors discuss scenarios of directional crack formation in front of the longwall.
