Abstract

Способ дегазации угольного пласта путем бурения наклонно-направленной скважины в породной формации, примыкающей к угольному пласту, или между двумя различными угольными пластами. Затем в скважине повышают давление для разрушения прилегающего(их) угольного(ых) пласта(ов) с целью повышения его проницаемости и выделения текучих сред из угольного пласта в ствол скважины для их последующего удаления из угольного пласта.
