摘要
本文针对探测煤矿采空区含水性这一问题,介绍了矿井瞬变电磁探测技术的方法、原理以及工作流程,并应用此技术对山西某煤矿进行了相关研究。结果显示:该煤矿六采区6112工作面切眼内帮在12m～50m、60m～90m以50m～-100m范围为低阻异常区,可能为K_2灰岩局部富水影响地段,说明在该区域局部相对富水且水性较强的。这印证了矿井瞬变探测技术在采空区含水性探测方面具有应用价值。
In this paper, aiming at detecting the problem of coal mine goaf, this paper introduces the method, principle and working flow of the mine's transient electromagnetic detection technology, and applies this technique to study a coal mine in Shanxi. The results showed that the 6122 working face in the 6 th mining area of the coal mine has an anomalous area with low resistance in the range of 12 m～50 m and 60 m～90 m in the range of 50 m～100 m. It may be the area where the K2 limestone is locally rich in water, indicating that it is in this area. Relatively rich in water and strong in water. This proves that the mine transient detection technology has application value in the detection of goaf moisture.
