Coalbed methane wells on the ground in coal mining areas are used to extract a large amount of gas from working face, but activities can cause strata movement, resulting casing deformation. Numerical simulation was study shear stress loading under thick alluvial conditions. The found that will have peak points at interface between aquifer, layer and bedrock, mudstone with intensity 49.9–77.1 MPa. point aquifer appear 4 m below floor as face is mined. junction bedrock increases linearly...
Permeability is a key factor affecting efficient gas drainage from coal seams, and acidification vibration shock are effective means to increase permeability in original low-permeability seams. To study the desorption characteristics of coking under coupling effect mining disturbance enhancement, taking seam Shoushan No. 1 as research object, self-built adsorption–desorption test platform was used. Acid leaching experiments at frequencies 0, 30, 60, 100 Hz were conducted on selected particle...
