Coal and gas outburst is a frequent dynamic disaster during underground coal mining
activities. After about 150 years of exploration, the mechanisms of outbursts remain unclear …

There has been a long history of using X-rays to visualize coal and its transitions during
various treatments. Advances and improved availability has allowed the application of X-ray …

Coal and rock mass bear loads together in underground engineering such as coal mining
and roadway support, resulting in different mechanical properties from those of pure coal …

In this study, uniaxial compression tests were conducted on the composite samples of coal
and oil shale characterised by high strength and low elastic modulus. Their fracturing and …

In this paper, we performed uniaxial compression tests on fine sandstone–coal, coarse
sandstone–coal, and oil shale–coal bi-material samples to investigate the lithology effects …

CH 4 adsorption-desorption-seepage characteristics of coal is an important indicator to
measure the gas extraction capacity of coal seam. The deformation of coal caused by CH 4 …

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding
the flow of gas in coal microstructure. The coal fines generation and migration are influenced …

In subterranean coal seam gas (CSG) reservoirs, massive amounts of small-sized coal fines
are released during the production and development stages, especially during hydraulic …

Coal seam gas (CSG), also known as coalbed methane (CBM), is an important source of
gas supply to the liquefied natural gas (LNG) exporting facilities in eastern Australia and to …

The mechanical properties of coal are important parameters for coalbed methane (CBM)
extraction and gas outburst control. However, the effect of adsorbed gas on strength cannot …
