Carbon dioxide (CO2)-enhanced coalbed methane recovery (CO2-ECBM) is a critical way to
increase methane production and reduce greenhouse gas (CO2 and CH4) emissions. As …

We explore the fully coupled thermo-hydro-mechanical-chemical (THMC) response of CO 2
enhanced CBM recovery (CO 2-ECBM) considering the coupling relationships of …

Methane extraction in deep coal seams is a multi-field coupling process affected by multiple
factors, and a systematic multi-field coupling theory is of guiding significance for ensuring …

Thermal enhanced methane recovery inevitably aggravates the soil and water loss, causing
severe harm to the sustainability of groundwater environment and the surrounding …

CO 2-ECBM is an effective energy saving and emission reduction technology. Among them,
the permeability of coal seam will affect the CO 2 injection efficiency, which is the key factor …

The permeability rebound and recovery are the key factors affecting the production efficiency
of CBM and the storage capacity of CO 2 during the CO 2-ECBM process. In this study, fully …

Gas extraction from coal seams is an extremely significant technical measure for preventing
gas hazards and predicting coalbed methane (CBM) reservoir. Gas diffusion and seepage …

We report laboratory experiments to investigate the dynamic failure characteristics of
outburst‐prone coal using a split Hopkinson pressure bar (SHPB). For comparison, two …

CO2-enhanced coalbed methane (CO2-ECBM) technology helps to store CO2 while
producing a clean source of energy (CH4) through the sorption process. This technique can …

Gas drainage in boreholes is characterized as an essential means to control abnormal gas
emissions during mining. Unfortunately, its drainage efficiency is terribly restricted by high in …
