Abstract: To address the issues of low training efficiency，high costs，inconvenience，and excessive carbon emissions from equipment in open-pit coal mines，a TIN (Terrain Information Network) was con⁃ structed for the production operation scenarios of open-pit coal mines，and a virtual simulation safety oper⁃ ation training system for open-pit coal mine excavators was developed. Using 3DS Max and Unity3D，the virtual 3D model of the open-pit coal mine was established and the environment was rendered. Meanwhile， a high-precision model of the excavator was created using MAYA to achieve the realistic reproduction of the open-pit coal mine excavator operation scenarios. Through analysis，the virtual interaction implementa⁃ tion method of the system was determined to develop the excavator driving simulation cabin and develop a data packet format for transmitting the operation data of the excavator driving simulation cabin. In an inno⁃ vative way，the virtual simulation scene interaction of the open-pit coal mine excavator equipment was re⁃ alized. Based on the program teaching theory，an excavator teaching and assessment system was estab⁃ lished. According to the excavator mining and loading operation procedures，the course design，excavator teaching，and assessment content were set，and the operators were evaluated and evaluated to improve their work efficiency and operational standardization. The results show that this system can realistically re⁃ produce the open-pit coal mine excavator operation scenarios using virtual reality technology. Through the excavator driving simulation cabin，the virtual excavator and the virtual operation scenarios interact in a deep way for open-pit coal mine excavator operation training in a highly safe environment，which can quickly complete the training of operators' work，improve their work efficiency，and achieve the goals of energy conservation and emission reduction. The research results provide a new approach for the training of open-pit coal mine excavators，and have certain significance for improving the safety management level of open-pit coal mines.
