  • Patent number: 9731903
    Abstract: Embodiments of this invention relate to highwall mining, and more particularly to a launch vehicle adapted for use in highwall mining of downward angled seams of mineable material, such as coal. More specifically, the provided launch vehicle includes a lower deck, an upper deck disposed above the lower deck, a launch deck pivotally attached to the upper deck, a first conveyor belt carried on the lower deck and a second conveyor belt carried on the launch deck. A conveyor car is positioned on the launch deck while the launch deck is in a substantially horizontal orientation, then the launch deck is tilted in a vertical place relative to the upper deck to substantially match a dip angle of the seam to be mined. The conveyor car is attached to a conveyor train extending into the seam as the rearmost car in the train.
