Abstract
A method of supporting opposite first and second walls of a mine passageway includes providing an elongate beam having opposite first and second ends and a longitudinal axis. The beam is configured to have substantial columnar strength for bearing a substantial longitudinal load applied to the beam generally longitudinally of the beam and substantial bending strength for bearing a substantial transverse load applied to the beam generally transversely of the beam. The method further includes selecting first and second locations on the first and second walls, respectively, providing suitable areas for supporting the first and second walls, and positioning the first end of the beam at the first location and the second end of the beam at the second location so that the beam extends between the first and second walls of the mine passageway.
