Abstract


Coal mining method includes open-pit mining and underground mining. there are impacts on each other’s security when the mining regional of the two methods are close enough, it’s a problem urgent to be solved that how to dynamically grasp spatiotemporal relationship of the two kinds of mine production and analyse the safe distance between the two kinds of mine to make sure the safty production .Based on analysis of theory of Open Pit and Underground Cooperated Mining digital mine, this paper analysis and determine the generating method of three-dimensional mine geologic entities and three-dimensional mine tunnel entities, and has developed a Open Pit and underground Cooperated Mining three-dimensional digital software which has already realized the function of three-dimensional modeling, solid model dissection,reserve calculation and automaticly forming columnar section .The software system has been applied to Pingzhuang Western Open-pit mine, and depending on it we have established the Pingzhuang Western Open-pit mine’s three-dimensional entity models of topographic and geologic, open-pit mining areas, tunnels of underground mining mine and goaf, and realized open-pit mining and underground mining’s data visualization. The establishment of three-dimensional models of digital mine provides a basis for the size calculation of Open Pit and Underground Cooperated Mining preserving protective pillar,and for the analysis of the distribution of coal resources and the reasonable formulation of coal resources exploitation plan and scheme.
