Rock bolting package usage

Claim 1

A METHOD OF REINFORCING AN EXPOSED FACE OF A ROCK WHICH COMPRISES: FORMING A COMPARATIVELY LONG SMALL HOLE THEREIN, FOLDING OVER TO FORM A POCKET THE END OF THE OTHER SEALED FLEXIBLE ENVELOPE OF A DUAL-COMPARTMENT RESIN PACKAGE COMPRISING: AN OUTER SEALED FLEXIBLE ENVELOPE HAVING A PLURALITY OF SEALED EDGES AND CONTAINING ALSO AN INNER SEALED FLEXIBLE ENVELOPE, THUS FORMING TWO SEPARATE COMPARTMENTS FOR STORAGE, ONE OF SAID COMPARTMENTS HAVING THEREIN FOR STORAGE, A FIRST COMPONENT (A) COMPRISING AN INTIMATE MIXTURE OF (1) AN ESSENTIALLY LINEAR POLYMERIZABLE UNSATURATED POLYESTER PREPARED BY REACTING AN ALPHA-BETA ETHYLENICALLY UNSATURATED POLYCARBOXYLIC ACID AND AN ALIPHATIC POLYOL; (2) A MONOMERIC CROSSLINKING AGENT FOR SAID (1) CONTAINING A CH2=CH< GROUP; (3) AN INHIBITING AMOUNT OF A PHENOLIC POLYMERIZATION INHIBITOR; AND (4) A PROMOTER FOR A PEROXIDE CATALYST; AND IN THE OTHER COMPARTMENT FOR STORAGE, A SECOND COMPONENT (B) COMPRISING (5) A CROSS-LINKING PEROXIDE CATALYST SYSTEM; AND MIXED WITH THE COMPONENTS IN ONE OF A AND B; (6) A WATER-REACTIVE FILLER, AND WITH THE COMPONENTS IN THE OTHER OF A AND B; (7) WATER IN AT LEAST A QUANTITY SUFFICIENT TO REACT WITH AT LEAST A SUBSTANTIAL PORTION OF THE WATER-REACTIVE FILLER AND ALSO MINIMIZE SHRINKAGE; AND IN AT LEAST ONE OF SAID COMPARTMENTS A AND B (8) A THICKENER TO MAKETHE MIXED UNSET RESIN THIXOTROPIC; WHEREBY WHEN THE CATALYST AND RESIN SYSTEMS IN COMPARTMENTS A AND B ARE MIXED, A QUICKSETTING THIXOTROPIC MIXTURE IS OBTAINED WHICH AT AMBIENT TEMPERATURES OF 40* F. TO 90* F. HAS SUCH THICKNESS THAT IT DOES NOT FLOW OUT OF A 1 1/2" HOLE FROM ITS OWN WEIGHT AND WHOSE VISCOSITY DROPS ON STIRRING WITH SUFFICIENT RAPIDITY THAT THE MIXTURE (A) MAY BE PUMPED, (B) MAY BE TRANSFERRED INTO AND PUMPED OUT OF A PLASTIC TUBE, (C) WILL FLOW INTO ROCK STRATA, AND (D) WILL RECEIVE A CONCRETE REINFORCING BAR UNDER HAND PRESSURE IN A DRILLED HOLE; AND ON STANDING IN A BORE HOLE AT AMBIENT MINE TEMPERATURES OF 40*F. TO 90*F. HARDENS TO A HIGH STRENGTH MASS IN ONE-HALF TO FORTY-EIGHT HOURS WHILE RETAINING SUBSTANTIALLY ITS ORIGINAL VOLUME; PLACING A SLENDER INSERTION ROD INTO SAID POCKET, AND USING SAID ROD AS AN INSERTION ELEMENT, PULLING SAID PACKAGE INTO SAID HOLE, INSERTING A REINFORCING MEMBER AND AGITATING SAID REINFORCING MEMBER AS IT IS INSERTED, THUS RUPTURING THE OUTER AND INNER ENVELOPES AND INTERMIXING THE CONTENTS AS THE REINFORCING MEMBER IS INSERTED INTO SAID LONG NARROW HOLE, THUS FILLING AT LEAST A SUBSTANTIAL PORTION OF THE PERIPHERAL SPACE BETWEEN THE INSERTED MEMBER AND THE WALLS OF SAID HOLE, DISCONTINUING SAID AGITATION, THEN CAUSING THE ADMIXED RESIN COMPONENTS TO REACT, THEREBY FIRMLY EMBEDDING SAID REINFORCING MEMBER IN SAID HOLE, THUS REINFORCING THE ROCK FORMATION.
