Abstract: It is very important for coal mine enterprises to realize the visual simulation of safety production based on three-dimensional space data of coal mines,and VRGIS is a feasible solution.A private cloud-based solution is proposed in view of the real obstacle of coal mines visual simulation.An private cloud architecture of coal mine visual simulation system based on VRGIS is built.The main contents of coal mine visual simulation system that should be completed is described in detail,which lays the foundation for visual simulation system of coal mine.
