VR Training and Assessment System for Hazard Identification by Tunneling Drillers

System Content:

System content includes:

1. Failure to sound the roof and sides

2. No temporary roof support

4. Loose drill bit installation, non-straight drill rod

5. Failure to use wet drilling

3. Failure to inspect air and water pipeline connections

6. Driller operating the drill while sitting on the air leg

7. Failure to inspect the condition of the drill rod

8. During drilling, the drill, drill rod, and drilling direction are not aligned, with uneven thrust

9. Failure to adhere to the "three tightnesses and two prohibitions"

10. Driller drilling too densely or sparsely, or at incorrect angles

11. Unstable work platform

12. Failure to stop drilling promptly when encountering pressurized water or harmful gas emissions

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 via VR controllers;

4. Supports user navigation in the system via controller operation;

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 scene.

Content Description:

1. Main interface

2. Scene of failure to sound the roof and sides

3. Scene of failure to use wet drilling

4. Scene of no temporary roof support

5. Scene of loose drill bit installation and non-straight drill rod

6. Scene of failure to inspect air and water pipeline connections

7. Scene of driller operating the drill while sitting on the air leg

8. Scene of failure to inspect the condition of the drill rod

9. Scene of misalignment between the drill, drill rod, and drilling direction with uneven thrust during drilling

10. Scene of failure to adhere to the "three tightnesses and two prohibitions"

11. Scene of driller drilling too densely or sparsely, or at incorrect angles

12. Scene of unstable work platform

13. Scene of failure to stop drilling promptly when encountering pressurized water or harmful gas emissions

After completing the current module, the system prompts "Press key to return to main menu," at which point the experience process ends.

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 spray and dust during operations.
