A mining system for advancing and retrieving a material transfer unit, such as a car, sled, beam or other vehicle commonly used in the mining industry to transport ores or minerals from a mine, into and out of a mine. A single material transfer unit is connected to a winch system which is actuated to advance the unit into the mine. A winch system is actuated to retrieve the unit from the mine with its load of mined product. The load is then removed from the transfer unit outside the mine so that it may be advanced back into the mine to retrieve another load. |
