Abstract

Способ повышения проницаемости для метана подземного угольного отложения посредством химической интенсификации образования трещин в угольном отложении с целью повышения скорости отбора метана из угольного отложения. Способ включает нагнетание газообразного окислителя в угольное отложение для интенсификации образования трещин в угольном отложении с последующим отбором метана из угольных отложений с повышенной скоростью. Газообразная смесь содержит озон, кислород и их сочетания. Заканчивание скважины, пробуриваемой в угольном отложении, облегчается нагнетанием газообразного окислителя в угольное отложение, окружающее скважину, до образования полости в угольном отложении вокруг скважины.
