摘　　要：为满足银山矿区井下大规模生产的要求,根据矿体前期圈定的产状及地质品位分布,采用水平钻进行生产探矿工作。通过分析探矿结果,进行矿体产状及品位分布的二次圈定。结果表明:生产探矿后进一步明确了矿体的发育形态,走向长度减少28.16m,厚度减少0.60m,面积重合率仅70.6%,形态误差率达81.8%,同时进一步明确了区域矿石品位及存量。探矿结果可进一步查明银山矿伴(共)生矿产资源的分布、富集和赋存状态,符合矿山综合回收、利用伴(共)生矿产资源的需要,提高企业综合经济效益。In order to meet the requirements of large-scale underground production in Yinshan mining area,according to the occurrence and geological grade distribution delineated in the early stage of ore body,horizontal drilling is used for production prospecting.By analyzing the prospecting results,the secondary delineation of ore body occurrence and grade distribution is carried out.The results show that the development form of the ore body is further clarified after the production prospecting.The strike length is reduced by 28.16 m,the thickness is reduced by 0.60 m,the area coincidence rate is only 70.6%,and the morphological error rate is 81.8%.At the same time,the regional ore grade and stock are further clarified.The prospecting results can further identify the distribution,enrichment and occurrence of associated(symbiotic)mineral resources in Yinshan Mine,which meets the needs of comprehensive recovery and utilization of associated(symbiotic)mineral resources in mines and improves the comprehensive economic benefits of enterprises.
