3D Visualization Of Ground Subsidence With Sub-level Caving Mining In Mining Area With Thick Alluvial Soil

Mining subsidence damaged the environment of the diggings seriously. In order to reduce even prevent the damage effectively, guide mining production correctly, and express mining subsidence with 3D computer visualization, it will improve the technical and application value of mining subsidence monitoring system.The data of mining subsidence is the base of mining three-dimensional Visibility. The paper put emphasis on the visual three-dimensional modeling technology and calculative method of probability integral in the mining subsidence on the bases of brief introduction of the basic theory of mining subsidence and visual three-dimensional topography, and probability integration is apt to adopt sub-level caving mining in mining area with thick alluvial soil.Then makes the point of data structure of mining subsidence according to its characteristics. After the handling of the subsidence data, it set force the three-dimensional model on the bases of them. The paper emphasized the method and developed the data structure. The key of this way is to automatically establish the three-dimensional model on the ground by the means of DEM in the area of subsidence.The MS Visual C++6.0 in this paper is the exploitive instrument to explore the function of the three-dimensional picture in the earth's surface moving predictive system. In this paper, the writer developed the achievement of the visibility in mining subsidence with the technology of three-dimensional topography, the information system in geography, the databases and the simulated calculative method in subsidence. All these methods can be used to renew and analyze the data in the mining subsidence and hit the target of reducing and preventing the damage caused by it. It turns out that the theory in this paper on three-dimensional visibility is practicable after the testing and verifing the system in the working face of YaKou mine of TongChuan.
