摘　　要：中山沟金矿是位于冀西北张家口市的1个中型金矿,现主要开采Ⅰ、Ⅱ号金矿脉,开采深度达到1 100m。以幔枝构造理论为指导,通过对矿床地质背景、矿田构造分析、成矿物质来源、矿脉垂向变化、矿床成因探讨等方面的研究表明:中山沟金矿由上往下矿体有宽度变大、品位变富的明显趋势,说明该矿深部仍有很大的找矿潜力,应该注重深部地质找矿。Zhongshangou gold deposit is a medium gold deposit of Shijiazhuang city in northwestern Hebei. No. Ⅰ and Ⅱ gold veins are being mined. The depth of mining is 1 100m. Take mantle-branch structure theory as a guide, the geological background of gold deposit, structural of the ore field, source of ore-forming materials, change in plumb direction and ore genesis are analyzed, The result shows that the width of mined deposit becomes bigger and the grade becomes richer with the depth increasing, which illuminate that the depth of the deposit provided with prodigious prospecting potential ,so prospecting in the depth of the mine should be paid attention to.
