Research Of Intelligent Decision System Based On3D Strata Model

The development of coal enterprises are moving towards digital,information-based development mode. Especially in the filed of intelligent decision and3D visualization is the only way which must be passed in the future. This paper mainly studied the intelligent decision system of mining and the improved algorithm of constructing the3D seams.SQL server2005database as the data platform for the input and output in this paper, the geological survey data,mining engineering data are managed by it, For establishing the3D coal seams, joining for mining plan preparation and laid the foundation of data management.This paper proposes the improved three prism triangulation algorithm, the study includes the following aspects:①improve three prism and it logical model.②improved three prism subdivision algorithm.③volume of improved three prism’s algorithm etc.. And the design the mathematical of coal reserves calculation, achieve by Visual LISP. By constructing the3D coal seam, visualization of coal seam and3D mining bridging program visualization and3D dynamic monitoring management of coal reserves.This paper developed MEIDSS mining intelligent system and IDSS System based on3D coal seam’s Intelligent Decision cohesion,the systems including:database management subsystem, model base management subsystem, the knowledge of mining plan extractive cohesion reasoning mechanism, And the library were added to the model time series model and neural network model; bridging the knowledge base for the preparation of mining; gives the mechanism of reasoning mechanisms MEIDSS system. Mathematical model for mining prepared,the amount of the mathematical model excavation, mining (cohesion) model, mining inspection mechanisms were studied. Finally, one colliery in Shanxi as an example,carried out the experimental system.
