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 substantially horizontally oriented control deck, a launch deck pivotally attached to the control deck, and a substantially horizontally oriented conveyor belt. A miner and at least one conveyor car are positioned on the launch deck while the launch deck is in a substantially horizontal orientation, then the launch deck is tilted upward relative to the conveyor belt to substantially match a planned entry dip angle of the seam to be mined. As the miner and at least one conveyor car advance into the seam, the launch deck is returned to a substantially horizontal orientation, an additional conveyor car is added to the launch deck, and the launch deck is again tilted to substantially match the entry dip angle of the seam to connect the additional conveyor car as the rearmost car in the conveyor train.
