A theoretically substantiated and experimentally verified calculation of changes in the methane yield from degassing boreholes upon a series of interval hydrofracking is given, exemplified for the conditions of S. D. Tikhov mine. Parameters of the borehole pattern and the area of hydrofracking distribution were defined.
