Deformation characteristics and outburst mechanism of coal mass ahead of working faces under dynamic disturbance induced by roof fracturing
For working faces in soft coal seams closely (especially directly) overlain by hard rock strata, intense dynamic disturbances induced by roof fracturing not only increase the susceptibility of coal and gas outbursts, but also lower the critical gas threshold for disaster initiation. However, existing studies on the...
