摘　　要：为探明杨涧煤矿3^#、8^#煤层采空区、富水区、采空积水区的赋存情况,依据岩层电性特征、放射性特征、区域地质、煤层发育等地质-地球物理资料,实施瞬变电磁法和同位素测氡法对测区进行综合勘探。研究表明,通过获得3^#、8^#煤层各测线的视电阻率拟断面图、顺煤层等值线图及氡气浓度分布平面图,可推断3^#、8^#煤层中7处采空区、10处富水区、3处采空积水区的位置。This paper intends to determine the occurrence of mined area,water-rich area,and mined-out water accumulation area of No.3 and 8 coal seam in Yangjing coal mine.The study involves performing the comprehensive exploration of the survey by applying transient electromagnetic method and isotopic radon measurement and using geophysical-geological data such as electrical characteristics,radioactive characteristics,regional geology,and coal seam development;and processing the observed data appropriately and thereby obtaining the apparent resistivity pseudo-sections,contour maps along the coal seam and the radon concentration contours of the survey lines on No.3 and 8 coal seams.The study ultimately deduces the positions of 7 mined-out areas,10 water-rich areas,and 3 mined-out water accumulation areas in above two coal seams.
