Deep coalbed methane (CBM) has emerged as an indispensable resource for expanding worldwide natural gas production and reserves. Nevertheless, the combined impact of in situ stress and moisture on gas adsorption properties under deep geological conditions remains poorly documented, severely restricting the efficient ex...

CO2 is usually injected into hydrocarbon reservoirs to enhance production while sequestering CO2 in the subsurface. Adsorption and induced swelling of CH4 and CO2 in dry and moist bituminous coal were simulated at the molecular level. The Langmuir–Freundlich-fitted maximum adsorption capacity and affinity index for C...

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...
