ABSTRACT:
A roller crusher is carried by a coal cutting mining machine which is, in turn, carried by a gantry for movement along the frame of a longwall face conveyor. The roller crusher is attached to the coal cutting machine by a U-shaped frame having hinge pins for pivotal movement thereof about a horizontal axis at the end of the machine which faces toward the oncoming stream of coal on the conveyor. The U-shaped frame supports a drive motor that is, in turn, coupled by a gear drive to the roller crusher. A piston and cylinder assembly is controlled to adjustably position the U-shaped frame and thereby the roller. The mining machine has support arms that are pivotal about horizontal axes and carry coal cutting drums to project into the working face of the mine.
