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 tightness 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.

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.
