Gas Measurement and Initial Reconnaissance After Mine Accident
Scenario record: it defines the environment, the mission flow and a proposed hardware and software configuration. The list below is a configuration proposal, not an installation inventory. Field projects lists deployed systems and their measurements.

The problem addressed
Rescue teams entering blind mine tunnels experiencing poisoning or secondary explosion risk.
Draft mission flow
- 1At the moment of collapse, the autonomous robot is sent into the tunnel before the rescue teams.
- 2Scans tunnel walls with Lidar in a non-light environment, simultaneously measures oxygen and explosive gas levels.
- 3Creates a real-time risk map indicating whether it is safe for teams to enter the tunnel.
Proposed hardware
- Multi Gas Analysis Sensor (CO, Methane, H2S)
- Lidar Based Scanner
- Dark Environment Depth Camera
Proposed software
- Navigation
- Non-light autonomy (SLAM) in pitch-black underground galleries
- Model
- Collapse Stability Analysis and Gas Dispersion Prediction
- Integration
- Mining Security Center Offline Network

Values are manufacturer data. Scenario fit is determined by comparing these limits with site conditions.
From scenario to installation
Feasibility is determined by the site survey: floor and route, network coverage, the charging point, intervention responsibilities and the conditions under which the robot must stop. The survey report defines the scope, the constraints and the commissioning steps.
