The training method of combining practical operation and virtual reality is adopted to construct the intelligent training operation base of coal mine and the immersive virtual reality environment, so as to realize the real-time linkage of “physical model and twin model” based on operation instructions. In a safe and real environment, users can quickly understand the core technologies such as intelligent mining machine operation, and master the internal structure and maintenance process of various equipment through MR holographic projection, so as to improve the training efficiency and reduce the training cost. At the same time, VR virtual simulation technology is used to simulate various disasters and accidents in underground mines, and users are personally involved in the process of experiencing accidents and deepening their impression. Therefore, it is used to improve the safety awareness of underground complex environment operation and achieve the goal of mine safety production.
