介绍了矿井瞬变电磁法(TEM)探测技术的工作原理及其在唐山矿业分公司Y257探巷水文地质探测中的应用效果。通过布置5个测点,采用不共面同轴偶极观测方式,初步查明在该巷道迎头前方约45m处富水性不均,为及时采取水害治理措施提供了依据。
This paper introduces the working principle of mine transient electromagnetic method (TEM) detection technology and its application effect in hydrogeology exploration of Y257 exploration lane of Tangshan Mining Company. Through the arrangement of 5 measuring points and the non-coplanar coaxial dipole observation method, it can be preliminarily identified that the water-rich unevenness is about 45m in front of the headway of the roadway, which provides a basis for timely measures for water damage control.
