Influence radius of gas extraction borehole in an anisotropic coal seam: Underground in‐situ measurement and modeling
Abstract Coal seam degasification by in‐seam drilling borehole is one of the popular techniques for coal mine methane (CMM) control. How to address the conflict between borehole numbers and drainage durations always arouses researchers’ interests. Furthermore, since coal has anisotropy structures, h...
