System Content:

The hazard identification module for rock bolt support operations includes:

1. Failure to sound the roof and sides

1. Failure to provide temporary roof support

1. Failure to inspect the connections of air and water pipelines

2. Failure to check the integrity of drill rods

1. Failure to adhere to the "three tightnesses" and "two don'ts"

2. Failure to use wet drilling

3. Use of anchoring agents not meeting operational requirements

4. Failure to install rock bolts and cables as per design specifications

5. Failure to perform secondary tightening of rock bolt nuts

6. Cutting rock bolts (cables)

7. Distance of rock bolts from shoulder sockets

8. Supporting roadways with significant deformation

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

2. Exposed rock bolts (cables)

3. Encountering pressurized water or harmful gas during drilling

4. Noise hazards during drilling and support operations with cable bolting 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 for realistic virtual reality rendering of underground working environments. Particle systems are used to simulate effects such as water spraying and dust during operations.
