| 中文摘要:采矿权的边界直接关系到采矿权人利益，也是最容易出现问题、引发混乱的重要环节，为此研究了基于双差层析成像技术的煤矿越界开采实时动态监测技术。该技术使用光纤微震传感器采集煤炭开采过程中采煤机产生的震动信号后，对光纤微震信号进行解调并增强处理，以其为基础，通过双差层析成像技术获得震动体波的相对位置和绝对位置，依据该位置结合煤矿开采权属界线位置，得到当前煤炭开采行为是否存在越界情况。实验结果表明：该方法可有效采集采煤机产生的震动信，并可有效对其进行增强处理，同时可生成震动信号的双差层析成像和实现煤矿越界开采实时动态监测，其具备较强的应用性。 |

| Real Time Dynamic Monitoring Technology for Coal Mine Cross Boundary Mining Based on Double Difference Tomography Technology |

| Abstract:The boundaries of mining rights are directly related to the interests of mining rights holders, and are also the most prone to problems and chaos. Therefore, a real-time dynamic monitoring technology for coal mine cross-border mining based on double difference tomography technology is studied. This technology uses fiber optic microseismic sensors to collect the vibration signals generated by the coal mining machine during the coal mining process, demodulates and enhances the fiber optic microseismic signals. Based on this, the relative and absolute positions of the vibration body waves are obtained through double difference tomography technology. Based on this position, combined with the position of the coal mining ownership boundary, the current coal mining behavior is determined to determine whether there is a boundary violation. The experimental results show that this method can effectively collect and enhance the vibration signals generated by the coal mining machine. At the same time, it can generate double difference tomography imaging of the vibration signals and achieve real-time dynamic monitoring of coal mining beyond the boundary. It has strong applicability. |
