摘要
团宝山铅锌矿探矿区地表条件恶劣,缺少矿化线索,探矿工作开展难度大。在张云湘等地质老前辈的辛勤工作下,团宝山铅锌矿曾经为国家经济建设做出巨大贡献,经过几十年开采,铅锌矿资源几乎枯竭。寻找新的资源,成为矿山的首要任务。笔者作为参与者,亲临了该矿山的接替资源勘查工作,经过各单位数年努力,找到了接替资源,使一座濒临闭坑的危机矿山,焕发出新的青春。通过大面积采用大功率激电方法圈定了12处激电异常区,划分出有效异常区3处,并经过进一步钻探和坑探工程实施获得了较好的找矿效果。团宝山铅锌矿矿区选择大功率激电方法找矿是深部找矿方法的一种突破,采用大功率激电扫面和测深,在平面上和剖面上圈定了矿化异常位置,为钻探和坑探等探矿工程实施提供了方向。
The surface conditions of the Tuanbaoshan Pb-Zn exploration area are poor with lack of mineralization indicators,so it is difficult to carry out the exploration work.The Tuanbaoshan Pb-Zndeposit has made great contributions to national economic construction thanks to the hard work of Zhang Yunxiang and other geologists.After decades of mining,the Pb-Zn resourcesof Tuanbaoshan Pb-Zndeposit are on the verge of exhaustion.Finding out new resources has become the primary task of the mine.This study uses high power IP method for delineating 12 IP anomalies in a large area 3 anomalies among which are effective.Good prospecting results have been obtained through further drilling and pit exploration.The application of high-power IP prospecting method to the Tuanbaoshan lead-zinc deposit is a breakthrough in deep prospecting.The mineralization anomaliesare delineated by means of high-power IP scanning and sounding on the plane and section which points out a direction for the drilling and pit exploration.
