Simulation Model Of Three. Dimensional Visualization Of The Change Of Mining Technique From Open Pit Mining To Underground Mining's Recovery Process And Stability Analysis

With the fast development of the mining industry in our country, the traditional geology survey method, mining technology and the manual handling have not solved the technical and managing problems yet, speeding up the digitization and the information construction have already become the development goal for many mine enterprises. At the same time, the strip mining changes into the underground mining is a aboard existent problem in mining realm, and is a problem which is need to solve for mining market's continual development.This article chooses the software SURPAC development by Australia SURPAC Minex Group as 3d simulation model construction platform and builds BenGang NanFen strip mine's the strip mining changes into the underground mining digital 3d mine model. We built the geologic model by the software SURPAC and Categorization of a group of rock according to the real facts, then transmitted it into the umbrella finite difference calculate software FLAC, carried out numerical simulation towards the ore body by spall, then we got the rule of the slope stability changing with the varying depth of excavation. They both provide reference for Mine changes into underground mining.The main work of this article is as follows:(1)Though the collection, collation and analysis of the NanFen strip mine's geological date, determine the feasibility plan of NanFen strip mine's the strip mining changes into the underground mining, and using the software SURPAC to build the simulation model of three-dimensional visualization of the change of mining technique from open pit to underground mining's recovery system.(2)Based on the real geological structure, using the software SURPAC to build the three-dimensional geological model and transmit it into the software FLAC, refining the technical problems which are encountered during the process of modeling by the software SURPAC and transmitted it into the software FLAC.(3)To conduct the mechanical simulation on the model that is transmitted into FLAC, and carried out numerical simulation towards the NanFen strip by spall. To do the mechanical analysis of the model, then get the distribution of the stress, the displacement and the plastic zone.
