Research On Modeling Method Of Digital Mine And Numerical Simulation Of Mining Process

Over the years, our country in the field of mining automation invested hundreds of billions of dollars, a substantial increase in the efficiency of production, although to mining enterprises to bring the opportunity, but is also bearing the enormous cost pressure, forcing mining operations to digital and intelligent road, with calculation of the rapid development of computer graphics technology and is becoming more and more mature, more and more enterprises in order to improve the rate of exploitation of resources, to reduce enterprise cost per ton of coal, relying on automation platform infrastructure planning of digital mine. From the point of view of 3D modeling system of digital mine, mine 3D modeling and information integration system is set up. The development direction of digital mine is built. The 3D modeling software is developed. The method of Voronoi is used to estimate the range of fault and fold geological structure. In the later period in order to study the process of mining of coal and rock system migration, data measured by sample parameters and tectonic force of geological structure, calculate tectonic forces involved in operation data, using the FLAC3D tool provided by excavation model of plastic zone, failure analysis model to simulate the advancing distance and roof subsidence, stress the size and the destruction of the roof structure, and indirectly validated the key factors of geological mining process of displacement and the theoretical results, the calculation results of the data assigned to the 3D discrete dynamic model for simulation, the same level of mining working face in the process of exploitation of coal seam and roof subsidence under pressure variation. The system can be integrated into the underground roof pressure monitoring data. It provides a prospective analysis of the changes in the mining environment by the necessary integration data. It provides a certain theoretical and technical support for the design of mining (mine design),3D geological section reconstruction and virtual exploration engineering.In general, it is difficult and key technology to construct the model of 3D geological dispersion model, which is based on the virtual reality technology, which is the key technology of 3D geological modeling system. This paper presents a new method to construct the model of 3D geological dispersion model, which is based on the analysis results.
