摘　　要：对采后空区的探测是后续对其安全防治及处理的基础,通过半航空瞬变电磁法对黄山铜镍矿30#矿体采后区域进行探测,将瞬变电磁响应得到视电阻率数据,与地质勘探岩性数据及中段采场布置图进行对比分析,结合三维成像技术对探测异常区进行圈定。结果表明矿区整体视电阻率异常区域与开采区域相一致,结合钻孔、微震监测等物探手段可大致确定采后异常区顶板高度低于600m,采区内覆盖层含水率较低且空区无明显冒落扩展情况。The exploration of postharmine goaf is the basis of subsequent safety prevention and treatment.The postharmine area of 30#orebody of Huangshan Copper-nickel mine was explored by semi-airborne transient electromagnetic method.The apparent resistivity data obtained from the transient electromagnetic response were compared with the lithology data of geological exploration and the stope layout map in the middle section,and the abnormal area was delineated with 3D imaging technology.The results show that the anomalous area of the whole apparent resistivity is consistent with the mining area.The roof height of the anomalous area is less than 600m,the water content of the covering layer is low and there is no obvious caving expansion in the goaf.
