3D geological modeling of surface coal mine based on AutoCAD

3D geological modeling of surface coal mine is a core component of Digital Mine.The establishment of 3D geological model provides decisions for the estimation and design of Open Pit Coal Mine,and the models have an important guiding significance during the mine's production and provide more important information for the designers.This paper,by taking specific surface coal mine for example,introduces the technique of 3D geological modeling of surface coal mine based on AutoCAD,builds 3D geological modeling of the mine,applies it in engineering,establishes 3D geological model,displays the 3D geological model in any direction,builds the drilling database,modifies and updates 3D geological model,simulation mining,and so on.The establishment of 3D geological model enables mining engineers in a real three-dimensional environment and in the approach of "human-computer interaction",so as to realize the mining design and mining plan,and so on.
