ABSTRACT:
A mine roof anchor assembly usable with a quick-setting resin cartridge inserted into a mine roof opening including an elongated bolt having a first end and a second end, the bolt being threaded for a portion of its length at the second end. A mechanical anchor is carried on the threaded portion of the bolt and extends along a longitudinal axis in a longitudinal direction. The anchor assembly further includes a resin mixer attached to the bolt extending below the mechanical anchor toward the first end. The resin mixer includes an open-ended hollow sleeve having flared ends integral with a tube-like section positioned therebetween. The sleeve also includes at least one outwardly extending integral fin extending in the longitudinal direction and having a maximum radial distance from the central longitudinal axis less than the mine roof opening radius. A frangible element may also be carried on the elongated bolt between the mechanical anchor and the resin mixer. A method of manufacturing a roof bolt assembly having a resin mixer is also disclosed.
