Abstract
An equipment recovery system for high risk environments such as high wall mine shafts has a vehicle that rides on a track including applications where a push-beam conveyor may serve as the track. The vehicle has a guide to keep it on the track and a hitch for attaching a recovery cable. The vehicle is remotely operated from outside the mine, has a power train for moving the vehicle, an implement for performing tasks, and carries an onboard power source and electrical control boxes to power and control the vehicle and implement. The vehicle may communicate with an outside operator station via an Ethernet cable and may employ and Ethernet extender for that purpose. The vehicle may have a camera to transmit video images. The vehicle may be operated from a high wall miner control center or from an operator station on a self propelled support vehicle.
