瞬变电磁在内蒙古锡林郭勒某煤矿富水区探测中的应用研究
Application of Transient Electromagnetic Method in Water-Rich Area Detection of a Coal Mine in Xilin Gol,Inner Mongolia
摘要
Abstract
To identify the water-rich characteristics of the roof of the 3-3 coal seam in a coal mine in Xilin gol League,Inner Mongolia,this study employed the ground transient electromagnetic method(TEM)to conduct high-precision detection in the study area.Based on the interpretation results of the regional electrical structure,a comprehensive analysis of inversion profiles and horizontal slices led to the identification of six typical low-resistivity anomaly areas.These anomalies were scientifically classified into three categories:water-rich anomalies in the roof strata of the coal seam,water accumulation anomalies in goal areas,and interference anomalies from artificial structures.The research findings indicate that the Ⅱ-D-4 anomaly area exhibits moderate water-rich characteristics and should be regarded as a key target for mine water hazard prevention.Particularly noteworthy is the spatial distribution of the No.Ⅲ anomaly area in the exploration zone,which aligns closely with on-site roadway water seepage phenomena.This finding effectively validates the reliability of the geophysical detection results.This study not only provides critical geophysical evidence for the precise prevention and control of mine water hazards but also demonstrates the technical applicability of the transient electromagnetic method under similar geological conditions through extensive practical application.It holds exemplary significance for hydrogeological surveys in analogous mining areas.关键词
