Provided is a novel rock bolt anchoring system and a method of use thereof. The system comprises: (a) a resin component, comprising an unsaturated polyester resin; and (b) a cross-linking catalyst component separated from the resin component. The catalyst component comprises a catalyst effective to cross-link the polyester resin, a filler and a propylene glycol. In the catalyst component, the catalyst is present in an amount from about 1 to 24 wt.%, the filler is present in an amount from about 48 to 90 wt.% and the propylene glycol is present in an amount from about 1 to 15 wt.%, based on the catalyst component. The system minimizes leakage during use, facilitates installation of a reinforcing member and is exceptionally fast in and strong upon curing. |
