摘　　要：煤炭作为我国国民经济的重要支柱,其深部开采面临复杂多变的地层特征,包括高地应力、构造应力变化及梯度差异,导致井下环境充满危险因素,水害尤为突出。瞬变电磁探测技术在近20年来取得显著进步,成为煤矿防治水工作的关键手段。本研究采用矿井瞬变电磁法,针对小纪汗煤矿特定煤层区域,详细探查了煤层顶底板含水情况。通过对瞬变电磁视电阻率数据的综合分析,我们成功绘制了等值线断面图和平面图,进而进行了地质推断,明确了煤层与上下含水层的分布情况。研究结果显示,煤矿充水强度较大,主要水源为顶板砂岩裂隙承压水。瞬变电磁法的应用,不仅精确界定了顶底板承压水聚集区,还为矿井开采与疏放水工程的科学布置提供了坚实依据,展现了该技术在实际应用中的高效与准确性。Coal,as an important pillar of China's national economy,faces complex and variable geological characteristics in deep mining,including high ground stress,structural stress changes,and gradient differences,which lead to hazardous factors in the underground environment,especially water disasters.Transient electromagnetic detection technology has made significant progress in the past 20 years and has become a key means of preventing and controlling water in coal mines.This study used the transient electromagnetic method in mines to investigate in detail the water content of the coal seam roof and floor in a specific coal seam area of Xiaojihan Coal Mine.Through comprehensive analysis of transient electromagnetic resistivity data,we have successfully drawn contour section and plan maps,and conducted geological inference to clarify the distribution of coal seams and upper and lower aquifers.The research results show that the water filling intensity of coal mines is relatively high,and the main water source is confined water from the fractures of the roof sandstone.The application of transient electromagnetic method not only accurately defines the gathering area of pressurized water on the roof and floor,but also provides a solid basis for the scientific layout of mining and drainage engineering,demonstrating the efficiency and accuracy of this technology in practical applications.
