Visual reserves computation and analysis with Cokriging method in 3D space

When the sample data of zinc mineral body is lack, it is essential to build one visualization model to compute and analyze its reserve by use of its associated copper sample data. In order to calculate the reserve of zinc mineral, the sample data in standard distance is used to compute its experiment variogram and analyze its corresponding structure. Thus, its visualization model was also established to determine the reverse of mineral body. According to the Cokriging method, the reserve visualization computation of zinc mineral body was implemented with the Open GL graphic function in the VC.net development environment. For the case with lack of zinc mine sample data, the zinc reverses could be figured out with its associated copper sample data, as described in Ashele zinc mine area. Furthermore, the Cokriging visualization computation procedure was given in this paper, and the profiles of mineral body are edited intelligently by using man-machine conversation. So, the mineral body could be located and presented dynamically. Meanwhile, the grades, reverses, and metal values could also be obtained directly and correctly by dividing the mineral body into different cells.
