笔者首先提出了煤岩变形破裂过程电磁辐射与应力耦合的概念,然后在实验研究、理论分析和数值模拟的基础上从力电耦合的角度研究了煤岩冲击矿压预测的电磁辐射法(EME)。研究结果表明:FLAC3D方法能对矿山巷道掘进过程煤岩内部应力场进行有效的数值模拟 电磁辐射信号主要来源于应力集中区,在场点监测到的电磁辐射信号主要是应力集中区煤岩变形破裂过程产生的 EME信号呈现出与煤岩内部应力变化相同的规律 利用力电耦合方法研究煤岩冲击矿压电磁辐射预测法是可行的。笔者最后还对未来煤岩冲击矿压电磁辐射预测法的研究进行了展望。-first author of coal and rock deformation and fracture process of electromagnetic radiation coupled with the concept of stress, then the experimental research, theoretical analysis and numerical simulations on the basis of Congli coupling angle of coal and rock rockburst forecast of electromagnetic radiation (EME). The results showed : FLAC3D method to mine tunneling process of coal and rock internal stress effective numerical simulation of electromagnetic radiation signal comes mainly from the stress concentration areas, the monitoring point to the presence of electromagnetic radiation signal is mainly concentrated stress coal rock deformation and fracture process of EME signal showing the internal rock and coal Stress changes in the s
