Experimental study and application of hydraulic fracturing in underlying coal seam
Meitan kexue jishuThe coalbed methane resource under goaf is rich, but has not been effectively developed for a long time. Hydraulic fracturing technology stands as an effective means to augment coalbed methane recovery.

Scientific ReportsA single load compression test of rock-coal-rock assemblages (RCRs) containing coal bodies with different inclinations was carried out with the research background of mining deep, large-steep coal seams. It was found that the larger the inclination angle of the coal body in the RCR samples, the larger the compaction stage of the samples and the smaller

Unloading damage mechanism and pore structure evolution characteristics of different coal and rocks
Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesThe final macroscopic fracture of coal rocks is closely related to their internal microscopic structure and micro-defects. The continuous change of the microscopic structure of coal rocks is the main reason for the change of the macroscopic mechanical ...
