瞬变电磁在煤矿突涌水预报及注浆中的靶向定位研究

Transient Electromagnetic Detection in Outburst Water Prediction and Grouting Target Location in Coal Mine

在煤矿和金属矿山的掘进和开采中,极易遭受不良含水地质体威胁,以内蒙古自治区某煤矿为例对瞬变电磁三维探测和注浆治理过程靶向定位进行研究。通过对掘进机卡陷区域多方位探查及巷道底板探查生成不良地质体三维电阻率等值线剖面图;瞬变电磁在注浆过程中的靶向定位方面,分别在注浆前、注浆中和注浆后进行跟踪探查,实时了解工作面前方不良含水体的存在情况,为注浆治理提供参考和保障。

Water burst disaster always treats the coal mine and mentat mine＇s tunneling anti mining, one coal mine in Inner Mongolia autonomous region is studied as an example to research transient electromagnetic three-dimensional detection and grouting process target positioning. 3D resistivity contour map is made by multi-dimensional exploration of machine card area and floor detection. Transient electromagnetic method is used in all the grouting period to target the water area, which can detect water scale and position and provide reference for grouting treatments and safety.
