| 摘 要： | 丁头山是一个老铅锌矿区,2014年贵州省普安罐子窑—水城花嘎铅锌矿整装勘查工作中,在物探方法试验的基础上,选用激电中梯剖面测量开展面积性测量工作。在圈定物探异常的基础上,对重点异常进行了激电测深和不同极距的电阻率联合剖面测量,在丁头山找矿靶区内,根据物探解译成果布置钻孔进行工程验证,在深部发现新的铅锌矿体,新增了铅锌资源量,取得明显的找矿效果。为研究物探手段在老矿区找矿工作中的应用方法及效果,结合前期工作成果,对如何运用物探方法在铅锌区域成矿带中寻找构造控制铅锌矿体进行了初步的探索,对老矿山增储具有一定指导作用。

| Abstract: | As an old lead-zinc mining area, Dingtou Mountain was detected in detail with geophysical methods of IP intermediate gradient during the package exploration of lead-zinc deposit in Guanziyao-Shuichenghuaga area, Pu''an of Guizhou Province in 2014. After delineation of geophysical anomaly, the authors measured the main abnormal areas through combination of IP sounding and different distance resistivity. In Dingtou Mountain prospecting target areas, through geophysical interpretation and drilling verification, the new lead-zinc ore bodies were found and resource amount increased, which was an apparent exploration effect. In order to study the application of geophysical methods and its effects in this old mining area, the authors discussed how to use the geophysical methods for finding tectonic-controlled lead-zinc ore bodies basedon preliminary achievements. This paper could provide some reference for raising reserves in old mines. |
