中文摘要：

基于麦克斯韦方程，本文对岩爆过程中产生的电磁辐射在煤层、岩石中的传播规律进行了理论计算．分析与研究结果显示：一方面，岩爆过程中产生的电磁辐射信号符合麦克斯韦方程；另一方面，数值模拟破裂过程电磁辐射在煤层、岩石中的传播时可将电磁辐射产生源理想化为水平电偶极子和水平磁偶极子的叠加；并得出了电磁辐射源产生的场在煤层、岩石中空间分布的解析计算式．麦克斯韦方程的应用对于岩爆等动力灾害预测的电磁辐射监测仪的研制和定向定位监测具有重要的理论和实际意义．

英文摘要：

On the basis of Maxwell＇s equations, the propagation rule of EME（electromagnetic emission） radiated from coal or rock in the course of rock-burst is studied and analyzed theoretically. It is shown that, on one hand, the propagation rule for EME signal produced in the course of rock-burst can be described with Maxwell＇ s equations, on the other hand, in numerical simulation of EME propagation, the source of EME could be decomposed to horizontal electric dipole and horizontal magnetic dipole. Additionally, the formula for calculating the distribution of EME in the coal or rock are obtained, which is the basis of developing EME monitor, directional and locating monitor.
