Annotation:
Technological schemes of safe development of steeply inclined coal layers disposed to gas-dynamic events are suggested. It is proved that application of hydrodynamic method for degassing and decrease of gas-dynamic activity is effective. The estimation of efficiency of hydrodynamic influence on the coefficient of degassing and amount of output of coal from a mining hole is given.
