几年来,我们在某铅锌矿区做了65平方公里的地表原生晕工作,圈定了14个异常带(图1);做了70个钻孔和4个中段坑道原生晕,圈定了4个矿化场(图2).对其中甲区铅铜矿化场的认识与地质评价意见一致,经过勘探获得了铅、锌、铜、硫的大型矿床,证实原生晕对指示深部矿化的有效性.我们对乙区运用地质、原生晕综合方法指导矿区评价工作,也找到了具有工业价值的铜、锌、铅、黄铁矿体,为保老矿山、建立新矿山扩大远景做出了一定的贡献.
Over the past few years, we have done 65 km 2 of surface primary halo work in a lead-zinc mining area, delineating 14 anomalous zones (Figure 1), making 70 boreholes and 4 intermediate tunnel dikes, delineating 4 mines (Figure 2). The understanding of the lead-copper mineralization site in A zone is consistent with that of geological evaluation. After the exploration, large-sized deposits of lead, zinc, copper and sulfur were obtained, demonstrating the effectiveness of primary halo to indicate deep mineralization We used the method of geology and primary halo synthesis to guide the mine area evaluation and found the copper, zinc, lead and pyrite with industrial value, and made a certain contribution to the protection of old mines and the expansion of new mines contribution.
