VR Training and Assessment System for Hazard Identification by Conveyor Belt Operators

System Content:

The hazardous source identification module for conveyor belt operators includes:

1. Failure to test belt coal accumulation before startup

2. Failure to check signal bells before startup

3. Not receiving signals

4. Failure to inspect belt joint conditions during operation

5. Using tools like iron shovels while the belt is running

6. Handling belt deviation without stopping the machine

7. Transporting oversized or overweight materials via conveyor belt

8. Sitting and watching the belt during operation

9. Long-distance belt transportation

10. Not activating head spray when transporting coal

11. Failure to stop under no-load conditions

12. Handling belt head failures without power-off lockout

13. During conveyor belt operation

System Functions:

1. User login authentication;

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

3. Supports user interaction with virtual equipment via VR controllers in a virtual environment;

4. Allows users to navigate the system using controllers;

5. Provides text and voice-guided operations;

The system enables six degrees of freedom (6DoF) interaction with VR controllers in an authentic 3D environment.

Technical Approach:

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