Study on Three-Dimensional Visual Simulation Technology and Its Application in Surface Coal Mine

Three-dimensional geological solid model of surface coal mine is constructed on the platform of AutoCAD. The determination of initial mining area, forming ditch and direction of working bench were optimized on the basis of geological model and mining model. In addition mining-stripping procedure is simulated. The specific method of three-dimensional visual simulation technology in surface coal mine is proposed. The present method has widespread guiding significance to surface coal mine design and production.
