VR Training and Assessment System for Hazard Source Investigation in Coal Mine Water Exploration and Drainage Operations

System Content:

The hazard identification module for coal mine water exploration and drainage operations includes:

1. Failure to inspect and reinforce the work area and surrounding support structures

2. Failure to secure the drilling rig with anchor screws

3. Failure to check the air volume at the work site and nearby areas before construction

4. Drill operators not wearing proper attire

5. Failure to promptly detect abnormalities during the drilling process

6. Absence at the drilling site

System Features:

1. User login authentication;

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

3. Supports user interaction with virtual equipment in the virtual environment via 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 an authentic 3D environment.

Technical Approach:

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