摘　　要：应用高密度电法之单边三极滚动测深对遵化市某铁矿采空区进行了勘察。结果表明,采空区引起的电测异常明显,物探圈定的采空区范围经钻探验证效果较好,为下一步采空区工程治理提供了可靠的资料。The unilateral three-electrode rolling sounding in high density resistivity method is used to prospect in a iron mine goal in Zunhua city. The results show the goaf caused electrical logging abnormal clearly. The goal delineation range has good effects,which is verified by drilling, and provides reliable in- formation for further goal engineering govermment.
