Abstract: In order to meet the requirements of the virtual simulation capacity of the digital mine, a 3D graphic engine and a virtual mine platform LR-VRMINE of th e mine was designed and developed.Thus a mine virtual system with the self independent intellectual property was formed and applied to the simulated monitoring and measuring of the electromechanical equipment. The mine virtual system could separate the graphic arithmetic and the applied platform to improve the development and operation efficiency and to enhance the expansionability.Meanwhile, a programming exaggerated pipeline technology was introduced by the system.The system improv ed the 3D modeling, the collision detection and other algorithm.As a result, the simulation effect and the smooth operation could be ensured and the resources consum ption could be reduced.
