摘要
针对目前矿井地震超前观测系统无法连接已有网络、仪器笨重、传感器安装繁琐等不足,设计了一种新型矿井无线多通道三分量分布式地震超前观测系统。通过对无线数据处理主机、无线AP路由器中继、无线数据采集终端、三分量气压式传感器、同步器的研制,实现了采集终端无线自组网、地震数据无线传送处理、分布式孔内高精度数据同步采集存储、三分量气压孔式检波及瓦斯预警综合分析软件接口。在实验室进行了观测系统采集信号幅度、相位一致性,以及静态噪声测试实验,并在甘肃大水头煤矿西部采区进行了现场工业性试验,结果表明:新型地震超前观测系统精度较高、稳定性较好,幅度和相位一致性高,本底噪声低;仪器轻便,功耗低,各项功能完善,能够满足现场探测的需要。
To counter to the current shortages of the mine seismic advance observation system which is unable to connect to the existing network, heavy in weight and has the complicated installation procedures of sensors, a new mine wireless multi-channel three-component distributed advance seismic observation system was designed. Through the development of the wireless data processing host, wireless AP router relay, wireless data acquisition terminal, three-component pressure sensor and the synchronizer, the wireless ad hoc network of the acquisition terminal, the wireless transmission and processing of the seismic data, the synchronous acquisition and storage of the high precision data in distributed holes, the three-component pressure hole detection and the comprehensive analysis software interface for early gas warning were all realized. In the laboratory, experiments were carried out on the consistency of the acquisition signal amplitude and phase of the observation system and the static noise, and then industrial tests were conducted in the western mining district in Gansu Dashuitou Coal Mine. The results show that this new seismic advance observation system has the advantages of high accuracy, good stability, high consistency of amplitude and phase, low background noise, light weight, low power consumption and perfect functions, and it can meet the requirements for site detection.
