摘　　要：为查明临汾矿区采空区分布范围,基于综合勘查应用实践,研究了临汾矿区采空区类型,开展了采空区调查与踏勘,提出了三维地震法、瞬变电磁法和可控源音频大地电磁法相结合的综合物探勘查技术。结论表明:临汾矿区分属于河东煤田、霍西煤田和沁水煤田,42座煤矿长壁采空区分布清楚,房(巷)柱式采空区多分布不详,顶板未垮落或部分垮落;采空区多位于2、3号煤层,为连片、多层、近水平~缓倾斜、浅层~中深、大面积采空区;调查与踏勘封闭不良井口或小窑142个,蓄水池等333个,泉207处,地表裂缝或塌陷区158处;综合物探勘查实践及案例表明,综合物探结果可靠,效果良好。In order to investigate the goafs distribution in Linfen Mining Area, based on comprehensive detection application practices,the types classification were analyzed and surface survey were carried out. Then the comprehensive geological detection methods were proposed combined time domain electromagnetic method, Controlled-source audio magnetotellurics method with 3 D seismic method. The results showed that Linfen Mining Area belongs to Hedong,Huoxi and Qinshui Coalfield of China. In 42 coal mines,the longwall mining goafs distribution were clearly while such shortwall mining goafs as room and pillar method goafs distribution were unknown and the roofs were partly caved or no-caved. The goafs of Linfen Mining Area were usually located in No. 2 coal seam and No. 3 coal seam,and they were continuous,multi-layers,nearly horizontal or slowly inclined,shallow or mid-deep buried,and large-scale area; through surface survey,there were 142 closed shafts or small coal pits,333 reservoirs,207 springs,158 surface cracks or subsidence. The comprehensive geophysical detection application practices and case analysis showed reliable results and good affect.
