Finally, we apply the evaluation method to Dongtan coal mine, Qianqiu coal mine, and others for verification. The study achievements can supply theoretical support for revealing the stress and energy fields, risk assessment in the fault mining area, and research on the evolutional mechanism of fault slip burst.
