Abstract: Shovel-truck technology,Bucket wheel excavator-belt technology(BWE in short) and dragline stripping technology all have the characteristics of large equipments being numerous,the organization management being complicated and the potential safety risk being big,And latter two are also all new production technologies of domestic,all of those cause the technique methods of highly effective direct-viewing production technology demonstration as well as safe training and the work risk study being the restriction factor whether the above crafts apply successfully.The technique path of simulating mining technology and risk state was studied,which was based on the virtual reality and the Pro-E and the 3 D MAX software were used.The virtual environment of person-machine-mineral in some large surface coalmine was set up,the process of BWE,shovel-truck and dragline stripping technologies were simulated intuitionally and visually,the important risking parts were identified dynamically at the same time.The system provides the platform for training the miners to master the operation process and the safety production.
