Abstract: In order to make up the blind zone in ahead detection of mine transient electromagnetic method(MTEM), adopted joint ahead detection combining mine transient electromagnetic method and infrared surveying method to realize precisely forecast in the front of tunnel.This paper studies the basic principles and feasibility of joint detection about method of mine transient electromagnetic and infrared surveying, introduces data acquisition, data processing and interpretation method of the joint detection, and combines with the -950 m boundary return air roadway of a mine in Shandong province as engineering application to complete joint ahead detection in these two methods finally, analyzes geological effect of joint detection, and verifies method effect comparing to expose actual roadway excavation.The results show that the joint ahead detection of mine transient electromagnetic method and infrared surveying method can not only learn from each other and complement advantages, but also improve the detection accuracy effectively, and have wide prospect of application.
