Abstract
A mining machine suitable for cutting roadways in coalmines comprises a cutting head, a conveyor for moving mined material rearwardly of the machine and a discharge conveyor for unloading the mined material to one side of the machine. As the machine advances the discharge conveyor can be used selectively to unload coal onto a stage loader and other material into packholes, thereby saving labor. The discharge conveyor may be pivotable about horizontal and/or vertical axes, longitudinally extendable or movable relative to the machine or cutting head to obtain maximum control over the area in which it discharges material.
