| With the presentation of "Digital Mine" concept and the development of theComputer Simulation and Visualization Technology, The three-dimensional modelingtechnology of mineral deposit has been mature.The construction of Digital Mine is aneffective approach to achieve scientific management and safety and high efficiencymining in mine enterprise.Complex using theory of geostatistics and three-dimensional modeling technol-ogy, the three-dimensional modeling of the saishitang copper deposit based onsoftware Surpac were researched in the paper. The main content of this paper are asfollows:（1）Based on the processing and analysis of the original data in saishitang mine,the geological database had been established and the visualisation of drill informationhad been realized.（2）Build3D solid models of surface and M2orebody using software Surpac andrealize the deposit3D visualization. The visualization of three-dimensional modelingcan completely and accurately display the spatial relation of the surface and M2orebody,and it can provide the foundations for the compilation of scientific productionschedule program in mine.（3）Using the theory of geostatistics, the combinatorial analysis of the drill sampledata was conducted. According to the statistic character of portfolio sample, theexperimental variation function was fitted. Based an above mentioned, logicalvariation function and block model of M2orebody were established.（4）Based on the built block model and using the method of ordinary Kriging, thecalculation of the grade were carried out. Through the establishment of the mine visualization of3D model, ore bodyshape and grade distribution can master more clearly, which later in mineresourceexploitation, economic benefit of mine plays a very important role in improving. |
