Study on the Low Resistance Interference Test of Coal Mine Transient Electromagnetic

The noise generated by the low resistance interference in the underworkings is the main factor influencing the forecast accuracy of the mine transient electromagnetic detection.In this paper,an instance test was used to analyze the degree of interference caused by different low resistance interferences in the roadway,and then improved the accuracy of the mine transient electromagnetic detection.Results showed that when encountered with low resistance interference during the transient electromagnetic detection in the mine,we can avoid interference caused by metal interference and water accumulation by adjusting the collecting ways.It can not only effectively complete the detection task,but also improve the efficiency of the detection work and the accuracy of the detection results.
