System Content:

Flood rescue includes: signs of water inrush (red seepage, sweating walls, water sounds, fog appearance, increased roof dripping, air cooling, water turbidity, increased harmful gases, fissure seepage), measures taken after detecting signs of water inrush, on-site emergency response, reporting to the emergency command center, actions after water inrush occurs, on-site emergency response, reporting to the emergency command center, activation of emergency plans, flood rescue equipment

3.2. Fire rescue: endogenous fires, exogenous fires, fires at key locations, intake shaft fires, return air shaft fires, vertical shaft fires, shaft bottom station fires

Gas accident rescue: gas asphyxiation accidents (regulations, ventilation restoration)

Roof collapse rescue: signs of roof collapse (support cracking sounds and damage, roof rock fracturing and impact noises, falling debris from roof, coal seam loosening, increased rib spalling, increased water inflow and dripping), roof support (portable supports, sleeve supports, U-shaped steel arch supports, bolt-mesh-beam (cable), bolt-mesh-shotcrete combination, bolt-shotcrete), roof collapse accident reconnaissance

System Functions:

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 using VR controllers;

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

Technical Approach:

The system is developed using the Unreal Engine, leveraging PBR materials to achieve realistic virtual reality presentation of underground working environments, and employs particle systems to simulate effects such as water spraying and dust during operations
