Cover Structure Optimization Study Based on the Drawing Theory of Random Media

Abstract

Abstract: Based on the analysis of the drawing theory of random media，the random media of the cover was produced by the PFC numerical simulation software.Combined actual situation of open-pit to underground mining in Xingshan iron ore，the main mining technical and economic indicators of the different thickness and composition of particle sizes were calculated.The displacement and velocity of different size particles in the process of mining were researched，and the optimization cover structure was put forward which were of great significance to the improvement of the ore technical and economic indicators.

Key words: Random media, Open pit to underground minig, Cover, Simulation
