ABSTRACT:
An apparatus for mining aggregate material from a seam includes a miner for cutting material from the seam and a conveyor for conveying the won aggregate material from the miner for recovery. The conveyor is formed by a series of individual conveyor units that are interconnected in series so as to form a train. Each unit includes a main frame supported on ground engaging wheels. A belt conveyor is supported in the main frame and a conveyor drive mechanism is provided on each unit. The apparatus also includes a launch vehicle. The launch vehicle includes a frame holding a conveyor for receiving won aggregate material from the conveyor train and for delivering that material to a discharge conveyor. The launch vehicle also includes a pair of spaced guide tracks adapted to receive and guide the wheels that support an end conveyor unit of the conveyor train. Additionally, the launch vehicle includes a reciprocating drive assembly to aid in advancing the conveyor train and miner into the seam face. In an alternative embodiment, the launch vehicle is replaced with a self propelled pusher unit. This unit includes receiving and discharging conveyors. Further, hydraulic jacks are provided on the pusher unit to advance the conveyor train and miner as desired.
