Abstract
A continuing mining machine wherein a crusher is placed inboard of the machine and has a dipper machanism as well as a loading chute. The dipper is of a twin handle type so that it can straddle a feeder chute thus affording a wide area for excavating. The placement of the crusher in a central location within the machine allows for stability and obviates the need for swivelling of the crusher during operation of the machine.
