Abstract
A mobile machine for use in opencast mining employs a chassis with endless tracks and the chassis has outriggers projecting laterally outwardly from the tracks. A hopper supported by one outrigger receives raw ore material excavated by another machine or machines. The raw ore material passes from the hopper to a screen arrangement with superimposed oscillating screens which sieve the material to separate the finer mineral ore product from the coarser spoil. The mineral ore product which passes through the screens is transferred by a multi-stage conveyor extending perpendicularly to the tracks to a separate conveyor laid on the floor of the working alongside a path of movement of the machine. The spoil is transferred with another conveyor to the inlet of a jib which extends laterally outwardly from the tracks opposite the hopper. The jib itself has a conveyor which transports the spoil along the jib which then discharges the spoil onto a dump.
