【摘要】：由于目前地下矿山开采位置难以自动实时监测，一些中小煤矿的越界开采引发了一系列的重大安全生产事故。针对这种现状，通过生产现场调研，本文设计了一个井下爆破震源实时监测与定位系统来实现对矿山地下开采位置实时监测：分布在矿区地表层的振动加速度传感器将同步监测到的爆破振动信号送给各自的信号采集分站，由分站对信号进行小波去噪处理、震相识别后，将爆破振动波到达传感器的初至时刻通过CAN总线送给主机，主机根据传感器阵列的空间坐标和爆破振动波到达每个传感器的初至时刻，，利用线性定位方程反演出震源位置，并将震源位置通过GPRS传送给主控机，在主控机上借助于LZ-TIP软件开发平台实现震源位置的可视化。在上述理论分析计算和实验室实验的基础上，将该系统在煤矿进行了现场试验，结果表明，该系统的可靠性和准确性达到了实用的要求，为下一步通过生产应用为煤矿的安全生产打下了坚实的基础。
[Abstract]:At present, it is difficult to automatically monitor the mining position of underground mines, and some small and medium-sized coal mines have caused a series of major accidents of safety in production. In view of this situation, through research on the production site, In this paper, a real time monitoring and locating system of underground blasting source is designed to realize the real time monitoring of underground mining position. The vibration acceleration sensor distributed in the ground surface of mining area sends the synchronously monitored blasting vibration signal. For their respective signal collection sub-stations, After the signal is de-noised by wavelet, the blasting vibration wave is sent to the host through the can bus after the seismic phase is identified, and the blasting vibration wave reaches the first arrival time of the sensor through the can bus. According to the spatial coordinates of the sensor array and the blasting vibration wave, the host computer reaches the first arrival time of each sensor, and uses the linear positioning equation to invert the source position, and transmits the source position to the main control machine via GPRS. Using LZ-TIP software development platform to realize the visualization of the source location on the main control computer. On the basis of the above theoretical analysis, calculation and laboratory experiments, the system is tested in the coal mine. The results show that the reliability and accuracy of the system meet the practical requirements. For the next step through the production application for the safety of coal production laid a solid foundation.
