为保证煤矿注浆灭火管路压力监测的可靠性,以长灌浆管路输送中管路压力监测为研究对象,阐述了实时监控的工作原理和主要功能,采用先进的智能化软硬件手段,设计出一套由可编程控制器与组态王监测软件相结合的注浆压力远程实时监控系统。最后,注浆压力实时监控系统在自然发火比较严重的阳泉矿区进行了现场应用,并将监控系统压力监测值和井下压力人工实测值加以对比分析。研究结果发现:两者监测压力的范围基本一致,误差范围在5%以内。 In order to ensure the reliability of coal mine grouting fire extinguishing pipeline pressure monitoring, taking pipeline pressure monitoring of long grouting pipeline as the research object, the working principle and main functions of real-time monitoring are expounded. The advanced intelligent hardware and software are adopted to design A set of programmable logic controller and Kingview software combination of grouting pressure remote real-time monitoring system. Finally, the grouting pressure real-time monitoring system was applied in the field of Yangquan mining area where the natural fire was serious, and the pressure monitoring values ​​of the monitoring system and the artificial measured values ​​of downhole pressure were compared. The results show that: the scope of monitoring pressure between the two basically the same, the error range of less than 5%.
