Definitions

  • the present invention relates to a stabilising bolt adaptor for use with a grouting injection drill head used in such applications, as underground mining.
  • the invention also relates to a grouting injection nut and a combination of grouting injection nut and a stabilising bolt and a method for their installation into formations such as rock, coal, soil, concrete or the like.
  • rock strata, coal, soil and/or concrete are typically stabilised by the use of stabilising bolts which are inserted into drilled holes and retained therein either mechanically such as by friction or chemically by grouting.
  • the installation of chemically retained stabilising bolts is typically a multistage process and involves drilling a hole ensuring that drilled fragments are flushed out of the hole, removing the drill bit, inserting a capsule of a grouting composition (usually a two part resin), inserting a stabilising bolt, spinning the bolt in order to rupture and mix the grouting composition, and allowing the resin to cure to thereby retain the stabilising bolt in the hole.
  • the free end of the stabilising bolt is typically secured by a nut usually together with a capping plate which is braced against the surface surrounding the drilled hole.
