Abstract
Provided is a novel rock bolt anchoring system and a method of use thereof. The reactive grouting system, comprises: (a) a resin component containing an unsaturated polyester resin; and (b) a catalyst component separated from the polyester resin. The catalyst component comprises a catalyst effective to cross-link the polyester resin and a filler having a proportion of particles having a size of from 0.01 to 100 (preferably from 0.5 to 50 .mu.m) and a mean particle size of 1 to 5 .mu.m (preferably 3 to 5 .mu.m). The system has particular applicability in the anchoring of mine bolts, facilitates installation of a reinforcing member, and is exceptionally fast in and strong upon curing.
