摘　　要：大厂矿田是我国著名的锡多金属资源产地,矿床具明显的平面展布和垂向分带规律。离地表600 m以深的"第二找矿空间"找矿潜力巨大。利用现代成矿理论和成矿预测理论,将地质综合研究、数学地质中的趋势面分析和物化遥等多种技术方法综合集成,其中地质综合研究确定找矿空间,趋势面分析得到地质体的变化规律和确定矿体的垂向空间位置,物化遥技术提供三维空间找矿信息。在三维空间上,对大厂矿田黑水沟-铜坑区深部靶区进行了成功的成矿预测,取得了良好的地质效果,通过验证,新增锌多金属资源量接近超大型矿床规模。Dachang ore field is a famous tin-polymetallic deposit in China with significant distribution rule on the plane and in vertical direction for ore deposit. The second ore-prospecting place, which is below the surface 600 meter, is of great potential in ore prospecting. Under the guide of modern metallogenic theory and metallogenic prognosis, various techniques and methods were integrated,including comprehensive geological study, trend surface analysis, and geophysics, geo- chemistry and remote sensing. Among them, the comprehensive geological study could determine the ore prospecting space, and the variation of geologic body and the vertical space of ore-body could be got by the trend surface analysis. The technique of geophysics ,geochemistry, remote sensing provided the three-dimensional space prospecting information. The mineralization prognosis in Heishuigou-tongkeng deep area in Dachang ore field is remarkably made with good results achieved. After prognosis verification,the new Zn-polymetallic resources are close to a super large deposit.
