The occurrence of dangerous coal and gas outbursts seriously threaten safety in
underground coal mining. Thus, defining the spatio-temporal evolution of the mechanisms …

Coal and gas outburst is a violent mechanical instability of gas-containing coal, and its
mechanism is crucial for prevention of gas dynamic disasters. The macroscopic instability of …

The accurate identification of gas migration channels and enrichment regions is essential for
the utilization of gas resources and safe coal mine production, which are closely related to …

Hydraulic flushing can increase the efficiency of gas extraction by artificially modifying the
coal reservoir. Considering the plastic failure of coal mass, an improved gas–liquid–solid …

Injection of gas mixture (CO 2/N 2) into coal seam can both enhance methane recovery and
reduce carbon dioxide emission. Coal permeability determines the mass transport speed …

Power ultrasonic assisted reservoir modification is a promising technique for enhanced
coalbed methane recovery. The current studies confirm the coal structural alteration and the …

The early prediction of violent coal-bearing strata failure using effective monitoring is crucial
to avoid losses due to catastrophic failures and geological disasters to ensure safe and …

Uncontrolled and excessive gas emission may affect normal production and even result in
serious disasters such as gas explosion and coal and gas outburst. To find out the essence …

The goaf is the main site of gas explosions in coal mines. A large number of accidents
indicate that the occurrence of gas explosion in the goaf is related to the deformation and …

Water-based SiO 2 nanofluid, a wetting agent, has been proved to be feasible in improving
the control effect of coal seam water injection against coal and gas outburst. However, the …
