综合物探法在矿山隧道勘查中的应用

Application of integrated geophysical exploration method in mine tunnel exploration

近年来对矿区长埋深隧道勘测技术的研究,一直是我国矿山隧道地质勘查中的研究难题,一般传统的钻探等手段在这类隧道有着很大的局限性,近些年来地球物理勘探方法逐渐被用于解决这类问题。本文以西气东输某工程为例,在某矿山隧道路段分别布置了地震浅层反射、音频大地电磁法,经过这两种方法的结合,有效的查明了工区的覆盖层厚度、基岩起伏形态、岩性分界线及不良地质体的展布情况。

In recent years,research on long-buried deep tunnel survey technology in mining areas has been a research problem in mine tunnel geological exploration.Generally,traditional drilling methods have great limitations in such tunnels.Geophysical exploration in recent years.Methods are gradually being used to solve such problems.Through the combination of these two methods,the thickness of the cover and the bedrock fluctuations are effectively identified.Morphology,lithological boundaries and the distribution of unfavorable geological bodies.
