摘要：

The distribution rules of stress fields of coal or rock failure have been simulated and analyzed by means of RFPA(2D) software and the coupling model of stress and electricity of electromagnetic radiation of coal or rock, then the macroscopic rules of electromagnetic radiation and the strength of coal or rock effecting on electromagnetic radiation are received. The results show that electromagnetic radiation pulse and energy increase with the addition of stress and at the main fracture of coal or rock, electromagnetic radiation signals reach the maximum; the strength of coal or rock strongly effect the peak stress of coal or rock and with the addition of strength of coal or rock, electromagnetic radiation pulse presents little descendant tend, electromagnetic radiation energy and the strength of coal or rock are positive correlation.
