Mining slow condensing resin anchor agent was prepared by unsaturated polyester resin,poly-merization inhibitor(hydroquinone and diethylene glycol),accelerating agent(CoNaP),evocating agent (methyethyl ketone peroxide)and inorganic filler,and it divided into two components(resin cement and curing cement),use the two components according to a certain proportion mixed. The best recipe of slow condensing resin anchor agent,which is resin daub recipe:unsaturated polyester resin 100 g,polymeriza-tion inhibitor 0. 3 g,accelerating agent 0. 5 g,middling flour 200 g,fine powder 300 g,white carbon black 2 g;curing agent recipe:evocating agent 4 g,White carbon black 1. 7 g;tested its gel time and compres-sive strength. The result indicates:gel time of the slow condensing resin anchor agent is 490 min and com-pressive strength is 61 MPa,which can satisfied demand of the new pulling force dispersion anchor cable technology.
