Based On 3 D Visualization Technology Drip Pond Copper Mining Method Optimization Research

The scientific use of resources is an important guarantee of the mining cost-effective. There are some problems of heavy workload and low effiency, if the information of geological and mining are managed by using the traditional two-dimensional mode in the mine production process. So it is difficult to achieve a variety of program research that is viable resource extraction scheme, and can not guarantee the scientific exploitation of the resources. In order to enhance the decision-making level of management in mines, how do we apply the application of3D visualization technology resource management into the mining, optimize the mining plan,evaluate mining plan and so on? In this area, it needs further study. This paper combined with TangTang Copper production status, applied the three-dimensional visualization technology to create the mine three-dimensional geological model,studied the three-dimensional mining program design and exploitation of program evaluation and other aspects.(1)The paper described the mine three-dimensional visualization technology research and its application status. According to the TangTang Copper production status, this paper determined the programs and technology roadmap of TangTang Copper mining method based on three dimensional visualization techniques and DIMINE3D mining software as a platform.(2)Depth introduct the3D visualization technology application infrastructure and key theories in mine,and described in detail the method of three-dimensional mine design based on DIMINE3D mining software.(3)According to the characteristics of the mining program evaluation, it pointed out the analytic hierarchy process to build the mining program evaluation index system. It build the judgment matrix by the method of the combination of1～9scale and two-stage scale, and used the least square method to get the mining program evaluation index weight. Starting from the connotation and extension of two aspects of the mining program evaluationm, it chose the fuzzy method and gray relational method to deal with the original index matrix,and construct the evaluation matrix. To overcome the problems of the weighted sum method with the methods of weighted sum and weighted product to get the final comprehensive evaluation index for evaluation of the mining program.(4)Through analysis the mine geological features, it is used the mine basic information to show the methods of mine three-dimensional geological modeling method by combining DIMINE3D mining software, and build the TangTang copper three-dimensional geological model,such as the geological database, surface model, fault model, ore body model, valuation model, engineering model and so on. It summed up the problems encountered in the current production of TangTang Copper by a detailed analysis of the status of mining.(5) Analysised by the occurrence conditions of the six middle of the1#,2#orebody, the stage forced caving method was selected as the mining method of ore block, on the basis of the second delineation of ore bodies within the scope of the study. And combined with DIMINE3D mining software, the bottom structure and mining program of six middle ore body has been optimized, and pointed out four possible drop-mine programs.(6)For stope603-2-1as an example,this paper has done the design of three-dimensional mining cut by raising four recovery program, and obtained the relevant parameters of the mining program evaluation, evaluated the various mining programs, determined a reasonable mining program, finally completed the research of optimizing the deposit of mining plan design and evaluation based on three-dimensional visualization technology.
