Abstract

Способ повышения добычи метана из подземного угольного отложения посредством химического стимулирования образования трещин в упомянутом отложении для повышения скорости добычи метана из упомянутого отложения посредством нагнетания водного раствора окислителя в упомянутое отложение для стимулирования образования трещин в упомянутом отложении; и последующая добыча метана из упомянутого отложения с повышенной скоростью. К числу подходящих окислителей относятся диоксид хлора, водорастворимые соли металлов: перхлорат, хлорат, персульфат, перборат, перкарбонат, перманганат и нитрат, а также их сочетания.
