Abstract: A mining machine including a frame, a cutting head moveably coupled to the frame and pivotable about an axis that is substantially perpendicular to a first mine surface, and a first actuator for stabilizing the frame relative to the first mine surface. The first actuator is coupled to the frame and includes a first end extendable in a first direction to engage the first mine surface. The extension of the first actuator is automatically controlled based on measurements of at least one indicator of the force between the first actuator and the first mine surface.
