Mining machines Mining extraction services

Abrégé

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.

Abrégé

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. As the conveyor train advances into the seam, the launch deck is returned to a horizontal orientation, an additional conveyor car is added to the launch deck, and the launch deck is again tilted to substantially match the dip angle of the seam to add the additional conveyor car as the new rearmost car in the conveyor train.

Abrégé

A mining apparatus includes a miner, a conveyor unit and a steering unit connecting the miner and conveyor unit. The apparatus also includes a heading sensor and a controller responsive to the heading sensor. A first actuator is carried on the miner, the control unit or the steering unit. The first actuator is positioned to a first side of a midline of the miner. Further a second actuator is carried on one of the miner, the conveyor unit and the steering unit. The second actuator is positioned to a second opposite side of the midline of the miner. The first and second actuators are utilized to adjust a connection angle between the miner and the conveyor unit either side of parallel in order to maintain the miner on the desired directional heading.

Abrégé

A launch vehicle (10) is provided for a continuous mining system including modular conveyor units (U) that are connected together to form a conveyor train. The launch vehicle (10) includes a main frame (12) for supporting a rearmost conveyor unit (U) of the conveyor train. The main frame (12) includes a first side over which additional conveyor units (U) are added to the conveyor train and a second side. A belly conveyor (14) is carried on the main frame (12). A drive assembly (42) is provided for selectively advancing and withdrawing the conveyor train. Further the launch vehicle (10) includes a canopy (18) overlying the main frame (12). The canopy (18) is mounted on at least one cantilever support (20) extending upwardly adjacent the second side of the main frame (12) whereby the first side is left open for adding additional conveyor units (U) to the conveyor train.
