Characteristics of Stress-Displacement-Fracture Multi-Field Evolution around Gas Extraction Borehole
To ensure the effectiveness of the gas extraction borehole, it is necessary to investigate the stress-displacement-fracture evolution of the coal around the borehole. In this study, by constructing a numerical model of a gas extraction borehole, the burial depth and side pressure coefficient are use...
