Abstract

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.

Keywords

Degassing, Interval hydrofracking, Borehole, Methane yield.
