Abstract
A low-profile mine roof support device comprises a roof plate and a barrel. The barrel includes a nose portion, a shoulder portion, and a tapered bore for receiving a cable to secure the roof plate to the mine roof. The shoulder portion of the barrel comprises a convex surface that seats against the plate. So configured, a majority of the barrel, which includes the nose portion and the tapered bore, passes through the plate and into a drilled hole formed in the mine roof, thereby advantageously minimizing the extent to which the support device extends into the workspace of the mine without sacrificing the length of the barrel.
