Evolution Model of Gas Pressure Around Coal Seam Boreholes and Determination of the Effective Drainage Radius

The effective drainage radius is a key parameter for borehole layout and gas drainage performance evaluation, and it is determined by the spatiotemporal evolution of gas pressure around drainage boreholes. Taking the M4–5 coal seam of a Xinjiang coal mine as the study case, the residual gas-content criterion was conver...

Influence of Temperature and Stress on Water Injection Seepage Behavior in Coal Fracture Network

Deep coal seams in China are generally characterized by high geothermal temperatures and high in situ stresses. Their coupled effects can alter fracture seepage conditions and promote gas-lock retention, thereby impairing water-injection seepage. However, the microscopic gas-lock evolution and the comparative seepage r...
