Optimization of Semi-continuous Process Based on Geological Model of Deposit

The optimization of selecting the mining technology of the surface mine is a complicated systematic project, and it involves many factors, such as, occurrence conditions of deposits, mining technology, production scale, and so on. According to geological statistics data of Shengli surface coal mine, the geological model of surface coal deposit is built, which divides the coal seams and cover layers into four parts and several benches based on cross section. Based on the preliminary analysis and comparison of mining technology, further economic comparison of technology used in different layers and different benches, system engineering viewpoints and methods to solve dynamic comprehensive optimization problem of mining process and mining technique, and reasonable selection of mining technology for different materials and different benches, shovel truck other moving crusher-belt conveyors technology ultimately is selected to be applied in the stripping for surface mine.
