Underground Mining TRIZ Cases
- Ore Transport Vehicle Flap-Conveyor Layout for Tunnel-Limited Loading
Rotatable side flaps around a conveyor create expandable ore storage, boosting fill rate and haul volume within mine tunnel size limits.
- Underground Mobile Positioning Using 3D Tunnel Ray Casting
Vertical ray casting on a 3D tunnel model resolves z-coordinate ambiguity from 2D underground vehicle position data.
- Underground Mobile Positioning with 3D Tunnel Z-Coordinate Resolution
Vertical ray casting in a 3D tunnel model resolves z-coordinates from 2D tracking data, removing ambiguity in overlapping underground tunnels.
- Underground Mining Machine Laser Guidance for Absolute Positioning
Rotating laser scans and reflective reference patterns give underground mining machines absolute position data without satellite signals or inertial drift.
- Maintenance Train Distance Monitoring for Collision-Free Milling Loadout
Automated sensor-based spacing control keeps milling and transport units aligned for safer, collision-free unloading during rail maintenance.
