Abstract
A sliding stabilizer is a machine for supporting the roof in the working zone of a mine. A sliding stabilizer operates in tandem with a mining roof support machine. A sliding stabilizer is capable of supporting the mine roof independently of the roof support machine. A sliding stabilizer has a peak roof covering, a flexible sheet that extends toward the roof covering of a support machine, and a rotating retractable leg. The retractable leg rotates from the mineral seam to inside the roof covering of a support machine. The retractable leg propels the peak into the working zone of the shearer. A sliding stabilizer supports a previously insupportable roof.
