ABSTRACT:
Mining apparatus for removing near surface narrow seams of mineral deposits such as coal without removal of overburden is disclosed. The apparatus comprises a horizontal coal mining machine which is adapted for use in cooperation with large scraper type earth moving machines or bucket type cranes utilized in strip mining operations. The horizontal mine apparatus comprises generally a wide track service vehicle on which an internal combustion engine and hydraulic motors are disposed. An elongated cutting tool for removing a mineral deposit in a deep slot having a large depth to thickness ratio is supported on an elevator assembly which is pivotally mounted to the vehicle chassis. Linear actuators are coupled to the elevator assembly and cutting tool for adjusting the elevation, sweep and pitch of the cutter assembly to accommodate various changes in elevation and slope of the coal seam.
