<p>A mine support assembly for use in a bore hole of a rock comprises a reinforcing member receivable in the bore hole for reinforcing the rock. The reinforcing member extends along a longitudinal reinforcing member axis and comprises an axially extending outer wall defining a lumen. The mine support assembly further comprises a rockbolt extending along a rockbolt axis and comprising a rockbolt distal section, a rockbolt proximal section, and a rockbolt midsection disposed therebetween, for dissipating dynamic energy. A portion of the rockbolt midsection is received in the lumen, and the midsection is axially slidable within the lumen.</p>
