摘要： A continuous miner having improvements therein for enabling the same to be advanced in a coal seam having a shortwall face extending concavely arcuate from one side wall defining one end thereof to another side wall defining the other end thereof about an axis spaced outwardly thereof in a cycle which includes positioning the continuous miner adjacent one end of the arcuate face of the coal seam, effecting a pivotal movement of the continuous miner across the face to a position adjacent the other end thereof about an axis spaced from the axis of the face both in a direction toward the face and in a direction toward said other end thereof to progressively remove a section of coal from the seam which extends inwardly of the face a distance which increases progressively in the direction of movement across the face and to progressively define an advanced face which extends concavely arcuate about said spaced axis of pivotal movement and then effecting a pivotal movement of the continuous miner across the advanced face from said other end to a position adjacent said one end about an axis spaced from the axis of said advanced face both in a direction toward the advanced face and in a direction toward said one end thereof to progressively remove a section of coal from the seam which extends inwardly of the advanced face a distance which increases progressively in the direction of movement across the advanced face and to progressively define a further advanced face which extends concavely arcuate about the spaced axis of the last mentioned pivotal movement.
