【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。更多还原

【Abstract】 The location of underground mining is difficult to be monitored automatically and real-timebased on the technology at the present time, that results in some small coal mines ming beyond oftheir mining area in profit-driven causing a series of major production safety accidents. In view ofthis situation, the real-time monitoring and positioning system for underground blasting source isdesigned to achieve the monitoring of underground mining location in this paper after researchingthe production field. The blasting vibration signal detected by the acceleration sensor distributedin the surface of the mine is sent to the corresponding signal acquisition sub-stations. The initialtime of the blasting vibration wave to the sensor is sent to the host computer through the CAN busby the signal acquisition sub-stations after the blasting vibration signal is wavelet de-noisingprocessed and identified the phase. The source location is calculated using a linear equationaccording to the spatial coordinates of the sensors and the initial time of the blasting vibrationwave to the sensor and transferred to the main control computer via GPRS by the host computer.The source location on the mining map is visualized by means of LZ-TIP mining softwaredevelopment platform. The system is conducted experments in the coal mines on the basis of thetheoretical analysis and laboratory experiments.The results show that the reliability and accuracyof the sysetm meet the practical requirements. The system has laid a solid foundation for the coalsafety production in the future.更多还原
