Abstract: In order to improve the informatization level of China's mining industry, 3D virtual geological model has very important significance to coal mining. By using stress testing, rock strength test of surrounding rock, peep and ground exploration data processing method combining the linear fitting of data, the data are imported into the mine three-dimensional geological model, based on ARTPN element method, according to corresponding correction profile and plane profile, multilayer three-dimensional geological model is formed, the 3D geological model has four main functions, three-dimensional roaming, information query and positioning function, spatial analysis function and the spatial analysis function, this modeling method can achieve the application of 3D virtual technology in mine industry.
