Abstract

See full text

A rock bolt includes an elongate tubular body with an internal bore. A filler material is insertable into the internal bore at one end of the elongated tubular body. The end of the tubular body is then deformed thereby using the filler material to seal the end of the bore. The filler material may be a non-metallic material, such as a tube of plastic.
