摘　　要：本文利用一套在矿山领域内具有先进水平的大型数字化矿山工程软件SURPAC,以贵州省松桃县道坨锰矿为研究对象,利用钻孔数据、样品化验数据等基础地质数据,建立数据库,然后按照设定的矿体圈定原则,分别建立地形模型、矿体模型、夹石模型,最终构建道坨锰矿的三维地质模型。在此基础上,进行样品品位插值,把矿体划分小块体,赋予小块体地质可靠程度、储量类别等属性,运用地质统计方法中的距离幂次反比法,进行剖面解译和样品组合,通过Surpac计算出道坨锰矿的资源储量,得出道坨锰矿资源储量为14073.62万吨。In this paper, we use a set of advanced digital mining engineering software SURPAC with advanced level in the field of mining to take Daotuo manganese mine in Songtao County of Guizhou Province as the research object. Using the basic geological data such as borehole data and sample laboratory data to establish the database, Set the principle of ore body delineation, respectively, the establishment of terrain model, ore body model, clip-stone model,and ultimately build road lump manganese ore three-dimensional geological model. On this basis, the sample grade interpolation, the ore body is divided into small blocks, given the small blocks of geological reliability, the type of reserves and other attributes, the use of geological statistics method of inverse distance power Method, the profile interpretation and sample combination, calculated by Surpac Road, lump ore manganese ore reserves, obtained Daotuo lump manganese ore reserves of 140,736,200 tons.
