Deformation Failure Characteristics of Coal Body and Mining Induced Stress Evolution Law
The results of the interaction between coal failure and mining pressure field evolution during mining are presented. Not only the mechanical model of stope and its relative structure division, but also the failure and behavior characteristic of coal body under different mining stages are built and d...
