摘　　要：瞬变电磁法作为一种高效的地球物理勘探技术,在岩土工程勘察中得到了广泛地应用。针对深部磷矿开采过程中形成的采空区,其独特的地电特性为瞬变电磁法的应用提供了理想的条件。采用瞬变电磁法技术对清平磷矿采空区的位置、形态进行精确定位,并评估其与富水破碎区的关联性。结合地质资料,对采空区及岩溶富水区的分布范围、积水情况等进行了深入的综合分析。为磷矿采空区的隐蔽致灾因素普查提供科学的参考依据,同时为磷矿采空区的地质特征评估和隐患识别提供新的技术手段和理论支持,进而为相关工程的安全运行提供科学基础。The Transient Electromagnetic Method(TEM),as an efficient geophysical exploration technique,has been widely applied in geotechnical surveys.For the voids formed during the deep mining of phosphorus ores,their unique geoelectrical properties provide ideal conditions for the application of TEM.The TEM technology is used to precisely locate the position and shape of the voids and to assess their association with water-rich fractured zones.Integrated with geological data,an in-depth comprehensive analysis has been conducted on the distribution range,water accumulation,and other conditions of the voids and karst water-rich areas.This provides a scientific reference for the survey of concealed disaster factors in phosphorus ore voids,and offers new technical means and theoretical support for the geological feature assessment and hazard identification of phosphorus ore voids,thereby providing a scientific foundation for the safe operation of related engineering projects.
