摘要
CSAMT(可控源音频大地电磁测深)法以其探测深度大、分辨能力强等特点广泛应用于金属矿产勘查,并取得常规电法所无法比拟的勘查效果,可圈定出矿体的空间赋存位置、规模大小。在商丘东芒山一带深部磁铁矿勘查工作,CSAMT法取得了良好的应用效果。作者通过对该矿区数据资料的处理和异常分析,推断出矿体深部富集区的位置、埋深和范围;并通过钻孔验证,体现了CSAMT法在攻深找盲中的应用有效性。
Because of the deeper probing capacity and higher resolution ratio, CSAMT （controlled source audio frequency magneto telluric sounding） method is widely used in mineral exploration with better prospecting effect than made by conventional method, can delineate the ore location and size. The CSAMT method obtains a good application effect in the deep magnetite exploration at East Mang hill of Shangqiu. Through the processing and analysis of abnormal data of the mining area, the authors concluded the location, depth and scope of deep deposit concentration area which were verified by drilling.
