Gas drainage pipe network leakage detection has extremely important practical significance for improving the gas concentration in underground coal mines. Based on this, a new type of pumping pipe network leak detector based on ultrasonic principle was introduced, and the leak detector was used to conduct leak detection on the gas drainage pipe network of Duanshi coal mine. The application results show that the new leak detector can accurately locate the location of the leakage source of the extraction pipeline. The detection accuracy can meet the needs of the coal mine site, and provide technical support for improving the gas concentration of coal mine underground and ensuring the safety of underground gas transmission pipeline network.
