Frontier mechanical issues of coal-rock-gas dynamic disasters

Deep coal mining encounters a complex engineering environment characterized by high in-situ stress, high gas pressure, high geothermal temperature, intense mining disturbances, and evident time effect. This multi-physical field coupling fundamentally distinguishes deep mining from a shallow condition and frequently lea...

Multiscale damage characteristics and energy evolution patterns of coal treated with supercritical carbon dioxide

Coalbed methane (CBM) reservoirs in China are typically characterized by low permeability, requiring stimulation techniques to improve gas recovery. Supercritical carbon dioxide (SC-CO2) fracturing has emerged as a promising waterless stimulation method, offering advantages such as improved reservoir integrity, the enh...
