Abstract: An elongate hollow rock bolt, bolt installations, and process of effecting the same, wherein the bolt is slightly over-size relative to the transverse cross-section of the mine roff hole or aperture in which the bolt is to be installed. The bolt has a radial, transverse polygonal cross-section formed by contiguous deflectable resilient sides provided with outwardly directed fins, the latter being tapered. When the bolt is impact-forced into a mine roof aperture, the fins are forced inwardly, deflecting the bolt sides which, owing to their resiliency, maintain the fins and the aperture wall areas contacting the same under compression, thus increasing the holding effect upon the bolt. The latter may be grouted in, and also may have a pre-installed bearing plate provided with an aperture and slide-slots accommodating the fins.

Abstract: Rock bolt structure and installation wherein the bolt takes the form of an elongate member having an enlarged head and also an elongate, blade-like shank. The opposite edges at the remote tip of the shank are slightly tapered, this to provide ease of installation in a rock formation hole or aperture.

Thus, when the bolt is driven into the hole, there will be a friction fit and hence a frictional retention of the bolt at its edges by the hole wall. A bearing plate will be provided, the same having a slotted aperture to accommodate the blade-like shank of the bolt. Additionally, a relief aperture will be provided in the bearing plate to accommodate insertion of a grout fitting. The latter is supplied an impact tool, the same also having a relief aperture accommodating the head of the bolt. The opposite sides of the bolt shank are preferably roughened, i.e.

Fin means are provided in sides or side portion, with the overall span of the fin means being greater than the bolt hole into which the bolt is to be impacted. The pin means are tapered so as to provide for ease of insertion of the bolt. Impaction of the bolt into a mine roof hole provides for a compression loading of the fins of the bolt shank such that these engage the aperture wall in a forced-compression state. Corrosion factors are limited to fin edge contact with the aperture wall of the bolt hole. Resilient sides' deformation at the core of the bolt shank is relied upon to compression load the fins for frictional contact with the aperture wall into which the bolt is implaced.

The fastener or nail is produced starting from a cross-sectionally circular nail wire stock which is profiled in two coldrolling steps. In the first step, the nail wire passes through a first roller trio, the section rollers of which roll cross-sectionally arcuate guide grooves into the nail wire stock.
