Abstract
A system for mine roof reinforcement includes a bearing plate and a tubular member with an inner surface, an outer surface, first and second free ends, and an enlarged portion disposed proximate one of the free ends. The system also includes a projectile and an insertion member for being received in the tubular member. In addition, a method for inserting a bolt in rock includes: forming a borehole in rock; placing a bearing plate with an opening therein against the rock so that the opening is aligned with the borehole; disposing a tubular member in the borehole and opening so that an enlarged end of the tubular member abuts the plate; and mechanically expanding the tubular member so that an outer wall thereof frictionally engages the rock.
