VR Training and Assessment System for Hazard Identification in Rock Bolt Support Operations

System Content:

The hazard identification module for anchor bolt support operations includes:

1. Failure to sound the roof and sides

1. Failure to provide temporary roof support

1. Failure to inspect air and water pipeline connections

2. Failure to check the condition of drill rods

1. Failure to adhere to "three tightnesses" and "two prohibitions"

2. Failure to use wet drilling

3. Use of anchoring agents not complying with operational procedures

4. Failure to install anchor bolts/cables as per design requirements

5. Failure to perform secondary tightening of anchor bolt nuts

6. Cutting anchor bolts (cables)

7. Distance of anchor bolts from shoulder niches

8. Supporting roadways with significant deformation

1. Exceeding the allowable unsupported roof distance during excavation as per operational procedures

2. Exposed anchor bolts (cables)

3. Encountering pressurized water or harmful gas emissions during drilling

4. Noise hazards generated during drilling and support operations with anchor cable machines

System Functions:

1. User login and 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. Supports user navigation in the system through controller operations;

Technical Approach:

The system is developed using the Unreal Engine, leveraging PBR materials to realistically present the underground working environment in virtual reality. Particle systems are used to simulate effects such as water spray and dust during operations.
