Semi Solid MR Coal Mine Tunneling Machine Operation Training System

At present, the coal mining industry is increasingly focusing on improving safety and operational efficiency, which has led to an increasing demand for training of coal mine excavation equipment operators, and the corresponding training costs have also increased. To alleviate these pressures, researching a training program for cantilever tunneling machines based on digital twin technology has become an innovative initiative. This article constructs a virtual environment for underground tunnels by combining mixed reality technology with physical entities. The operator commands the activities of the virtual tunneling machine through actual control of the equipment, and the system evaluates the operation process by tracking and analyzing the operator's posture, ultimately generating detailed evaluation scores. This innovative training model not only greatly enriches the user training experience, but also provides comprehensive data support, which helps to improve the skills and work efficiency of operators, and meets the new requirements and development trends of coal mine safety production.
