ABSTRACT:
A mining system for remotely mining ores and minerals which protects against falling rock and allows evacuation of a miner and conveying system in the case of a cave in. A shield is advanced into a mine. Within the shield, the miner and conveying system are also advanced into the mine independently from the shield. The shield may be used with miners and conveying systems in common use. The cover of the shield protects the miner and conveying system from falling rock. In the event of a cave in, the shield provides a cavity for safely removing the conveying system and miner from the mine.
