Abstract
An elongated hopper for unloading a haulage vehicle for mined material has a length at least equal to the length of the haulage vehicle. The elongated hopper has a plurality of connected sections and each section has a horizontal conveyor pan with an L-shaped side member pivotally connected to each edge. A conveyor extends throughout the length of the hopper. The haulage vehicle is driven into the hopper through the inlet end prior to unloading and mined material is continuously discharged from the haulage vehicle onto the conveyor in the hopper as the haulage vehicle is driven out of the inlet end of the hopper.
