| The master dissertation title of The Mine Three Dimensional Digitization and The Exploration Prospects of TongKeng-LongTouShan Tin Diggings In Guangxi DaChang is selected based on the cooperation item between Huaxi corporation and Kunming University of Science and Technology named "The Synthesis investigation of Tongkeng-Longtoushan Diggings In Guangxi DaChang"(Serial number:200545022).Since the modernized industry and the modernized agriculture have appeared,, with the rapid development of economy, it is growing day by day to our country demand of the mineral resource, but now the resource guarantee degree of main ore kinds of our country is quite low, and the situation of mineral resource is very severe, so it has already severely threatened the economical security and the social stabilization of our country. Guangxi DaChang super large Sn-Ti-Zn-In muti-ploymetal deposit is the important tin producing area in our country and world. Up to present, its exploration has long history, especially after the massive exploration after Liberation, the resource crisis is very severe. To change the situation, we must depend on the progress of science and technology, and research actively the new and more effective mineral resource prognosis system of united modern metallogenic prognosis theories and high-tech, to advance whole the level of the mineral resource survey and estimation and the ability of scientific prognosis of our country, to search and find new mineral resource kinds and types, to increase the reserve of mineral resource, to provide the resource guarantee for the secure, highly effective and continual economical development of our country.The paper introduced the deposit digitization theory and correlating domestic and foreign mining software and its present research situation, on the basis of full analysis and research to the geology characteristic of TongKeng～LongTouShan tin Diggings in Guangxi DaChang, using the mining software SURPAC established 3DGM(3Dimension Geo-science Modeling) and using STAT geological statistic software to multianalysis the elements in Diggings. Do the research of the prospecting of the deposit depth and nearby based on the digitized deposit, define the prospecting targets and optimize them. Finally it can give strong evidences to prognosis in 3Dimension and provide the evidences for the metallogenic prognosis. According to the actual situation of TongKeng-LongTouShan tin Diggings, through studying the digitization model, We has mainly yielded the following results:(1) Established Terrain, Stratum, Geologic structure, Lava and the hole primary halo of three dimensional digitized model of TongKeng-LongTouShan tin Diggings in Guangxi DaChang, formed the 3Dimension Geo-science Modeling.(2) By the 3Dimension Geo-science Modeling, we may inquiry the material data, may add, delete and revise the database according to the need of the mine; And realize to draw the singularity by the dynamic multi-plans, it has practical significance to resource exploration prospects.(3) By the 3Dimension Geo-science Modeling, we can quickly calculate singularity and grade of the singularity get the reserves reports, graphs and pictures according to some characteristic, use the computer to plan geologic map of the mine automaticly. That enhances Exploration automaticity of the mine.(4) By the 3Dimension Geo-science modeling, according to research of cluster analysis and factor analysis, we can open out the elements assembled accretion and the evolutional characteristics of geochemical elements.(5) According to the information of Geo-science Modeling, based on the elements assembled accretion, we protract the singularity isoclines of the elements in different altitude. Matched for 3D space and the elements singularity of the ore body, we define the prospecting targets and optimize them. |
