煤矿井下长距离乳化液管路监测系统

Long-Distance Emulsified Liquid Pipeline Monitoring System in Coal Mines

摘要: 针对煤矿井下长距离供液乳化液管路运行情况监控困难、泄漏难发现难处理问题，本文设计并提出一种适用于长距离管路的液体泄漏、超压监控技术。通过对管路流量、温度、压力、振动等信息进行监测，综合评判管路介质传输状态，对管路连接点进行泄漏检测，通过电控阀门及时控制分段管路开通/关闭，减少发生泄漏时管路中乳化液损失。长距离乳化液管路监测系统预期在降低工作面开采停机方面带来直接经济效益，预计在维护供液系统平稳运行具有重要现实意义。

Abstract: In response to the challenges of monitoring the operation of long-distance emulsion pipelines in coal mines, such as difficulties in detecting and addressing leaks, this paper designs and proposes a monitoring technology suitable for liquid leakage and overpressure in long-distance pipelines. By monitoring parameters such as pipeline flow, temperature, pressure, and vibration, the system comprehensively evaluates the medium transmission status of the pipeline, detects leaks at pipeline connection points, and promptly controls the opening/closing of segmented pipelines through electrically controlled valves. This helps reduce the loss of emulsion in the pipeline during leakage incidents. The long-distance emulsion pipeline monitoring system is expected to bring direct economic benefits by minimizing downtime in mining operations and holds significant practical importance for maintaining the stable operation of the liquid supply system.
