Abstract
A material delivery system conveys material from a supply location at or above an area surface to a working location below the area surface. The delivery system includes a supply hopper located at the supply location and having an inlet for receiving material to be conveyed and an outlet for discharging material. An injection hopper is adapted for mounting on a movable working arm of a self-propelled vehicle, and has an inlet for receiving material and an outlet for discharging material. The arm of the vehicle carries the injection hopper below the area surface to the working location. A supply line is connected to the outlet of the supply hopper and to the inlet of the injection hopper for conveying material from the supply location to the working location.
