Assignee:

Mining Technologies, Inc. - Ashland KY

International Classification:

E21C 2900
E21C 3520

US Classification:

299 18

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 coupled or interconnected in series so as to form a train. The coupling comprises cooperating clevises and tongues interconnected by locking pins. 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. 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.

Abstract:

A launch vehicle is provided for a continuous mining system including modular conveyor units that may be connected together to form a conveyor train. The launch vehicle includes an elongated frame that holds a belt conveyor for conveying aggregate material that is received from the conveyor train. A drive assembly for selectively advancing and withdrawing the conveyor train is also provided on the launch vehicle. Additionally, the launch vehicle includes a mechanism for adding a modular conveyor unit to the conveyor train. More specifically, the conveyor train drive assembly includes a pair of cooperating tandem drive cylinders. Each drive cylinder includes a pusher arm unit that is adapted to engage one of the modular conveyor units of the conveyor train. The conveyor unit adding mechanism includes a positioning mechanism that holds and places a conveyor unit on the launch vehicle. A pusher cylinder is also provided to push the new conveyor unit into engagement with the rear of the conveyor train.
