Gas Outburst Accident Precursor VR Experience is a virtual reality technology application designed to provide people with a more intuitive and realistic experience by simulating scenarios of gas outburst accidents, thereby enhancing awareness and understanding of such incidents. In this VR experience, users can wear a VR headset and enter a virtual coal mine working environment. Through realistic visuals, sound, and haptic feedback, users can immerse themselves in the atmosphere and conditions of coal mine operations. During the experience, users will encounter various precursors that could lead to a gas outburst accident, such as increased gas concentration in the coal seam, abnormal gas variations in the mine, and unusual geological structures. Users need to observe, analyze, and make judgments to take timely measures in response to these precursors and prevent accidents from occurring. Through this VR experience, users can gain a more intuitive understanding of the precursor characteristics of gas outburst accidents, improving their ability to identify and warn of potential incidents. Additionally, since it is a virtual environment, the risks and dangers encountered during the experience do not cause actual harm, allowing for safer learning and training. In summary, the Gas Outburst Accident Precursor VR Experience is an innovative educational and training method that enhances people's awareness and response capabilities regarding gas outburst accidents, thereby reducing the occurrence of such incidents.

System Features:

1. User login authentication;

2. The system includes training mode and assessment mode. In assessment mode, the system can submit user assessment results to the backend management system;

3. Supports user interaction with virtual equipment in the virtual environment using VR controllers;

4. Allows users to navigate through the system using controller operations;

5. The system provides text and voice prompts for operations;

6. The system supports six degrees of freedom (6DoF) interaction with VR controllers in a realistic 3D environment.

Technical Approach:

The system is developed using the Unreal Engine, leveraging PBR materials to create a realistic virtual reality representation of the underground working environment. Particle systems are used to simulate effects such as water spraying and dust during operations.
