Coal mine training system based on virtual simulation technology

In order to improve the safety factor of coal mine production，enhance the safety skills of miners and increase the efficiency of mine，the paper discusses the importance of coal mine practice training system based on virtual simulation technology and briefly introduces the key technology of virtual reality.The coal mine safety training system has been exported with Adobe Photoshop software、3Dsmax software、Unity3d software and other tools.Through the image，sound，text，three-dimensional roaming and other forms，it simulates the surface and underground environment，and achieves multiplayer online interaction.The system has been used，with authenticity，security，interaction，effectiveness and other characteristics，is a highly efficient and reliable practice of coal mine training.
