Research on Construction Method of Fully Mechanized Coal Mining Equipment Workspace Based on Virtual Reality

In order to solve the problem that it is difficult to extract the working attitude of fully mechanized coal mining equipment in real-time in the existing monitoring methods, a method for constructing the working space of fully mechanized coal mining equipment based on virtual reality is proposed. First, the key information points were patched on the hydraulic support and scraper conveyor model, and the space-time kinematics relationship between the fully mechanized coal mining equipment and the 3D geological model was built in the virtual reality engine Unity3d; Then the initial working curves of the hydraulic support and scraper conveyor were extracted, and the reliability of the method was verified by virtual experiments. Finally, the support space of hydraulic support and the working space of fully mechanized coal mining equipment are constructed by using the key point marking method. The results show that the working space constructed by this method can reflect the working trajectory of the equipment more realistically. This method provides a theoretical basis for extracting the working attitude of fully mechanized coal mining equipment in the fully mechanized coal mining face.
