【摘要】 为了弥补矿井瞬变电磁法超前探测中存在的盲区,采用矿井瞬变电磁法和红外测温法进行联合超前探测,以实现掘进巷道前方准确预测预报。本文探讨了矿井瞬变电磁法和红外测温法两种超前探测方法的基本原理和联合探测的可行性,介绍了联合探测的数据采集及数据处理和解释方法,最后结合山东某矿-950m边界回风下山掘进巷道进行两种方法联合超前探测的工程应用,分析了联合探测的地质效果,并与实际巷道掘进揭露情况进行对比,验证了方法的效果。研究表明,利用矿井瞬变电磁法和红外测温法联合进行超前探测,可以取长补短,优势互补,有效提高探测精度,应用前景广阔。更多还原

【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 mboundary 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.更多还原
