Research On Three-dimensional Mine Simulation Based On3DMine

The21century is the information technology and digital age. The rapid development of computer information has a serious impact on the ancient mining industry, so the digital mine will be an inevitable trend in the development of mining industry.The3D mine is the key technology in the digital mine. With the development of3DGIS and computer graphics technology, the3D geological visualization technology can be achieved and is applied to some mine engineer software. This article studies and analyzes the principles and methods of constructing3D mine model. With the help of3DMine engineer software researched and developed by the country itself, the process of3D mine model is constructed and pointed out the problems in the constructing process, and it is on the basis of Ke xing Pingquan Coal Mine in Jincheng city of Shanxi Province. At last, the coal reserves in NO.15coal seam are calculated by the unique coal reserves calculated method of3DMine. The mine study achievements in this article are as follows:(1) The article sets forth some kinds of methods of3D space construct model, analyzes and compares the present situation of3D geological body at home and abroad, and introduces the present situation of3DMine engineer software in the study of3Dmine model.(2) The geological database is constructed in this area with drilling data and coal quality information. The article analyzes the structure formula of geological database, and constructs the model of the whole coal seam and tunnel entity and geological section and so on to provide some services for the mine production.(3) The article constructs the block model in this mining area on the basis of the whole coal seam entity model in Pingquan mine area, it analyzes the constructing principles and methods of block model,uses distance power estimating method, and draws up the distributed map of coal seam according to its heat.(4) The article sets forth the general method of resource reserves estimate, mainly introduces the principles of coal reserves estimate in3DMine engineer software and estimates the amount of pure coal after removing dirt band in3DMine engineer software in the example of NO.15coal seam.
