To explore the effect of different functional group fractures in coal on the adsorption
characteristics of CH 4, molecular models of bituminous coal (Wiser) with fractured oxygen …

The confinement effect in nanopores significantly impacts the phase behavior of fluids in
unconventional reservoirs and controls the occurrence and transport of fluids. As a result …

Coalbed methane (CBM) is an unconventional natural gas that possesses significant
impacts on energy supply, mining safety, and environmental conservation. CBM is primarily …

Systematic understanding of the occurrence mechanism of multiple fluids in coal reservoirs
is the basis for efficient development of coalbed methane (CBM). In this study, the adsorption …

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 …

In this study, a series of asphalt-derived hierarchical porous carbons (A-HPCs) were
synthesized using a chemical activation method with potassium hydroxide. The adsorption …

Respiratory dust is the primary factor triggering pneumoconiosis. Accurately separating
respiratory dust from total dust according to specific criteria are key aspects of respiratory …

Gas transport within the coal matrix is key to realizing mass exchange between the fracture
