1. High-fidelity simulation of the underground coal mine environment

Use 3D scanning technology to reconstruct underground coal mine scenes and facilities.

2. Realistic simulation of rock layer movement before roof collapse

Simulate micro-movements and cracks in rocks before a roof collapse through computer animation.

3. Virtual experience of the impact during a roof collapse

Accurately simulate the audio-visual effects of a roof collapse in VR.

5. Display historical roof collapse accident cases

Use accident site photos and data for case presentations.

6. Virtual experience of being trapped

Simulate the perspective of miners trapped after a roof collapse.

7. Emergency rescue drill for accidents

Simulate rescue procedures after an accident to improve emergency response capabilities.

8. Analysis of accident causes and prevention methods

Use accident reconstruction technology to analyze the causes of roof collapses and explain prevention methods.

9. Assessment and training system

Design a corresponding assessment system for risk prevention training.

This VR system can enhance miners' safety awareness and risk prevention capabilities.

System Features:

1. User login and permission 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 the system using controller operations;

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

6. The system enables 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.
