摘要
随着矿井开采不断延伸,水文地质条件日趋复杂,探放水作业频繁,作业过程中常出现孔口管液漏,严重时直接影响矿井安全生产。基于此,提出了基于光纤传感器的高可靠矿井液漏监测系统设计。该系统采用节点化设计,各节点选用光纤液漏传感器作为前端感知层,CC3200无线通信模块作为中间数据传输层,无线液漏监测上位机作为后端数据解析及液漏事件预警监测层,对探放水任务过程中的矿井作业管道进行高精度定位的液漏实时预警及监测。实验结果表明,各节点能对液漏位置提前预警、实时监测、精准识别,定位精度达到0.01 m。
With the continuous extension of mine mining,hydrogeological conditions are increasingly complex,and water exploration and release operations are frequent.In the process of operation,orifice pipe leakage often occurs,which directly affects the safety of mine production in serious cases.Based on this,proposed the design of high reliability mine fluid leakage monitoring system based on optical fiber sensor.The system adopts node-oriented design,each node selects optical fiber liquid leakage sensor as the front-end sensing layer,CC3200 wireless communication module as the intermediate data transmission layer,and wireless liquid leakage monitoring host computer as the back-end data analysis and liquid leakage event early warning and monitoring layer,so as to carry out real-time warning and monitoring of liquid leakage in high precision positioning of working pipelines during the water exploration and release task.The experimental results show that each node can provide early warning,real-time monitoring and accurate identification of the liquid leakage position,and the positioning accuracy reaches 0.01 m.
