Discrete Element Simulation of Fracture Evolution around a Borehole for Gas Extraction in Coal Seams

[Image: see text] The stability analysis of underground caverns, tunnels, and boreholes is of great significance to underground engineering. In order to study the stress change of the coal around a hole and the evolution law of fractures during the coal seam drilling process, the discrete element si...
