摘　　要：抗得弄舍金多金属矿床位于东昆仑成矿带的东南段,金矿体赋存于下二叠统马尔争组火山岩与石炭系浩特洛洼组灰岩的层间断裂破碎带中。根据矿床地质勘查工程资料,应用Micromine软件创建矿床数据库,建立了矿区地表和矿体三维模型,形象直观的展现了矿区地形地貌、矿体展布位置及形态。应用距离反比法插值的品位块体模型,清晰表达了矿体品位在三维空间的分布位置及变化情况。估算的资源量与传统地质块段法估算的资源量进行对比后,表明采用该软件估算的矿体资源量可靠准确,计算过程高效、便捷。Kangdenongshe gold-polymetallic deposit is located to the southeastern section of the East Kunlun metallogenic belt,the gold orebody occurs in the inter-layering fracture zones between the lower Permian system of Ma＇erzheng Formation volcanics and the Carboniferous system of Hao＇teluowa Formaton limestone. According to the exploration program conducted previously, the deposit database, surface DEM, orebody model have been established by Micromine software. As a result, the shape and physical features of the prospecting area of the ore body has well been established by the 3D model. The grade block model constructed by Inverse Distance Method shows distribution patterns and variations of the grade in three dimensional space.Comparisons with the results from conventional Geologic Block Method indicate that the mineral resources calculated by Micromine software is absolutely reliable, simultaneously the calculating process is definitely efficient and convenient.
