摘要：
Based on the coupling mechanism of stress and electricity of EME of coal or rock and the theory of statistic damage mechanics, the coupling model of stress and electricity of EME of coal or rock is established in this paper, which is modified by simulation study on Weibull morphological parameter m. Then this model becomes more accurate and useful. The value of m and EME of different coal or rock samples are simulated by using the modified coupling model of stress and electricity of EME of coal or rock. The simulation results of EME of coal or rock are consistent with experiment results, which have very important significance in numerical simulation of EME and homogeneity analysis of coal or rock.
