In view of the comprehensive geophysical prospecting method , especially the magnetic method and controlled source audio earth electromagnetic method (CMAST) effectively guide the first deep drilling construction in the Kangzhangzi area in the west Liaoning province . As the amount of resources to further expand the working area , the magnetic anomaly of C1 and C2 was studied , C2 magnetic anomaly was dis-sected by using the CMAST method to further determine the geological cause of magnetic anomaly . Com-parative analysis of the results of the comprehensive geophysical prospecting method and the existing ex-ploration and production data eliminated that the C 2 lower magnetic anomalies caused by rock mass of Kan-gzhangzi area , and deduced the deep structure , lithology of strata and geological body contact line . Anom-aly geophysical features of high magnetic , high polarization , low resistivity of the "two high and one low"displayed the occurrence of concealed ore body . Under the guidance of the magnetic method and the CMAST method , the ore rate of deep drilling engineering is above 95% in Kangzhangzi area , the prospec-ting result has expanded year by year , the final submitted a medium -sized iron polymetallic deposit of mo-lybdenum , the final realization of resource exploration breakthrough in the periphery and deep of the Xiao-jiayingzi old mining .%鉴于综合物探方法 ,尤其是磁法和可控源大地音频电磁法(CSAM T法)有效指导了辽西康杖子区首批深部验证钻孔施工 ,为进一步扩大工作区的资源储量 ,对有价值的C1、C2磁异常进行了再研究 ,采用可控源音频大地电磁法(CSAM T )对C2磁异常进行解剖 ,进一步确定引起磁异常的地质原因.通过综合物探方法探测成果与已有探、采资料的系统对比分析 ,彻底排除了康杖子C2低缓磁异常由岩体引起的可能 ,并推断了深部构造、岩性层位、地质体接触界线 ,认为高磁、高极化率 ,低电阻率的"两高一低"物探异常特征是隐伏矿体的赋存显示.在磁法和可控源大地音频电磁法(CSAM T法)综合成果指导下 ,康杖子区深部钻探工程见矿率高达95% 以上 ,探矿成果逐年扩大 ,最终提交了一处中型铁钼多金属矿床 ,实现了肖家营子老矿区外围深部资源勘查实质性突破.
