Methane Production Rate in Hydraulic Fracturing of Coal Seams

The common constraints of coal production under conditions of deeper level mining and methane release in mined-out voids in Kuzbass are described. The theoretical calculations of gas release from coal seams during multiple hydraulic fracturing are elaborated. The revised procedure of gas flow rate from coal seams, based on the data obtained in gas drainage boreholes during multiple hydraulic fracturing is theoretically and experimentally justified.

Automated summary

This study describes the common constraints of coal production under conditions of deeper level mining and methane release in mined-out voids in Kuzbass. It elaborates on the theoretical calculations of gas release from coal seams during multiple hydraulic fracturing and justifies the revised gas flow rate from coal seams based on data obtained in gas drainage boreholes during multiple hydraulic fracturing, both theoretically and experimentally.
