Abstract
The present invention relates to a system for recovering a continuous miner arrangement from a tunnel. The system includes a coupler for coupling the continuous miner arrangement to a pulling apparatus. The pulling apparatus pulls the continuous miner arrangement from the tunnel. Advantageously, the pulling apparatus may pull the continuous miner arrangement from the tunnel, either fully or partially until the continuous miner arrangement may once again retract from the tunnel under its own power.
