Abstract:
Cable bolt structure, related components and method for achieving desired ground control of mine roof strata in a dynamic manner; a sustained transverse enlargement, of particular design, of a portion of the cable bolt employed coacts with a tubular member to elastically expand the latter, whereby to generate a heightened frictional resistance as between the cable bolt and such tubular member, for achieving desired strata control.
