摘　　要：在一维煤岩力电耦合的损伤力学模型基础上,建立了三维煤岩力电耦合模型。利用该模型分析了电磁辐射脉冲数、幅值与应力之间的关系,并对煤岩内部结构的围压条件对应力和电磁辐射的影响进行了模拟,最后分析了单轴压缩突然卸载的电磁辐射特征。研究成果应用表明,该模型分析煤岩损伤具有可靠性、先进性。Based on damage mechanics model of one-dimensional mechanical and electrical couple of coal and rock, the damage mechanics model of three-dimensional mechanical and electrical couple of coal and rock is setup. Using the model, the relationship among electromagnetic radiation pulses, the amplitude and stress is analyzed. The effects of electromagnetic radiation and stress impacted by confining pressure conditions of the internal structure of coal and rock are simulated. Finally, the electro-magnetic radiation characteristics of sudden unloading uniaxial compression are analyzed. Application of research results show that ： the model is reliable and advanced to analyze the characteristics of damage mechanics of coal and rock.
