Abstract: The 3D simulation system of coal mine laneway is a complex technical system based on computer graphics，artificial intelligence，network technology，image processing，speech processing and high performance computing.It can realize the simulation of 3D scene under different conditions.Based on the OpenGL（Open Graphics Library)，and in Visual C++ 6.0 integrated development environment，the 3D tunnel simulation system was designed to solve the key problems among them.The system can simulate the external and internal conditions of roadway and finally realize the roadway owning the sense of reality through mapping.The simulation system of mine roadway is a set of hardware and software equipment using virtual reality technology.The tunnel 3D scene based on roadway data，principle of roadway establishment and image data makes users easily understand the underground tunnel，and provides reliable guarantee for safe development of coal mine as well.

Key words: Mine laneway, Virtual reality, Simulation system
