摘要：
The mechanism is considered for developing the induced gas-permeability region in the initially impermeable coal seam. Coal shrinkage and rock pressure are the determining factors of the mechanism in question. It is shown that, depending on the geomechanical conditions, both stable development of gas-permeability region and cessation of this process are possible.
