In order to solve the problem of rib spalling of high coal walls in fully-mechanized (HCWFM) mines, we used the principle of damage mechanics to analyze coal wall rib spalling. The results show that coal wall rib spalling is, to a certain degree, a macro-performance of the development of micro-cracks. We built a mechanical model to simulate the damage to …
