Research on Determination of Coal Pillar Bearing Law and Width Based on Coal Damage Evolution

In order to solve the on-site problems of unclear coal pillar bearing law and difficult determination of reasonable width, this paper uses numerical simulation and on-site industrial tests to analyze the wall rock deformation law, coal pillar bearing property evolution law, the law of internal crac...
