在煤矿地质灾害中,煤矿采空区的地质灾害是其中主要的一部分,加强对这煤矿采空区的勘察,积极排除隐患是消除地质灾害隐患的重要措施。瞬变电磁法是目前煤矿采空区常用的勘察方法,具有高分辨率、探测地质体耦合性好、对低阻地质体反应灵敏等特点,并且在进行施工和操作方面都相对的简单易懂。本文主要介绍了瞬变电磁法主要特点及其勘察的可行性。
In the geological disasters of coal mines, geological disasters in the coal mined-out areas are the main part of them. Strengthening the investigation of the coal mined-out areas in this coal mine and actively eliminating hidden dangers are important measures to eliminate hidden dangers of geological disasters. Transient electromagnetic method is commonly used in coal mined-out area survey method, with high resolution, geophysical exploration coupling well, sensitive to low resistivity geologic body and so on, and in the construction and operation are relatively easy to understand . This paper introduces the main features of transient electromagnetic method and the feasibility of its investigation.
