Coal in a natural geological mass is typically heterogeneous, potentially containing widely
distributed faults that affect gas migration and are closely associated with the occurrence of …

In order to clarify the characteristics of gas-bearing coal adsorption-instantaneous pressure
relief deformation, and reveal the mechanism of the effect of gas desorption on the outburst …

After coal seam water injection, coal mechanical properties will change with brittleness
weakening and plasticity enhancement. Aiming at the problem of coal damage caused by …

Coal is a kind of rock with the characteristics of soft structure, developed joints, cleats,
cracks, and pores, resulting in that its mechanical behaviors are highly sensitive to stress …

In coal mining activities, the abutment stress of the coal has to undergo cyclic loading and
unloading, affecting the strength and seepage characteristics of coal; additionally, it can …

In the process of coal-gas outburst, the gas-solid two-phase flow of pulverized coal and gas
will induce large-scale damage to underground mining. In this work, in order to study the …

The hydromechanical behaviour of fractured coal is a complex function of interaction
between coal bulk and fracture deformation driven by fluid pressure and external stress …

The deep highly gassy soft coal seam has the characteristics of high ground stress, high gas
pressure, and low permeability. In the process of coal roadway excavation, there are …

Rock burst occurs frequently as coal mining depth goes deeper, which seriously impacts the
safety production of underground coal mines. Coal seam water injection is a technique …

The primary purpose of this paper is to research the law of gas seepage considering gas
desorption in heterogeneous coal theoretically. A mechanical model on gas seepage …
