A feeder arrangement for a slurry transport system, which is preferably a hydro hoist, includes a chamber with a high pressure water inlet, a low pressure water outlet, and a low pressure solids inlet at a top end. The low pressure solids inlet has a transfer chute that opens into a lower section of the chamber to maintain a clear-water environment adjacent the top end. A high pressure solids and water outlet is provided at a bottom end. The inlets and outlets are controlled by suitable valves. Three such chambers are preferably operated together in sequence between incoming and outgoing columns in a mine.

A system for mining material in an underground tunnel, comprises a rail on the roof of the tunnel. A tram is supported on the rail and is movable along the rail. The tram has a conveyor for moving material along the length of the tram. Material is transferred to the tram by a loader which is also supported on a rail and movable along the rail. The conveyor has a ramp with a loading conveyor for transporting material upwardly along the ramp. Material is discharged from an upper end of the ramp onto the tram conveyor.

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.

An inclined shaft continuous feeding system for solid backfilling materials includes a surface loading system, an inclined shaft transportation system, and a downhole unloading system. The inclined shaft transportation system is arranged between the surface loading system and the underground unloading system. The inclined shaft transportation system includes a bottom unloading dumper, support guide wheels, a guide rail, a drive wheel, a reverse wheel, and a traction steel wire rope configured between the drive wheel and the reverse wheel. The present invention can realize a steady, continuous and efficient transportation of the solid backfilling materials from the surface to down hole. Moreover, the material transportation system does not wear easily, has long service life and low material transportation cost.
