Abstract
An apparatus applies mesh from a roll to a face of a mine passage. A spindle is adapted for supporting the roll of mesh. An arm supporting the spindle extends in a generally vertical direction and is adapted for rotation about an axis aligned with a direction of elongation of the mine passage such that the spindle traverses a path for applying the mesh from the roll to the face. A mast independent of the arm carries a drill head for drilling into the face of the mine passage. Related methods are also described.
