发明名称 ANCHORING SYSTEMS FOR MINES
摘要 A grouting system for anchoring a reinforcement in a mine includes a package that is a tubular member formed of polymer film and has discrete first and second compartments. Hardenable cementitious material that is a hydratable substance and water is disposed in the first compartment. A method of forming a resin grouting capsule includes: injecting a hardenable material into a first compartment of the capsule having resin mastic; wherein the hardenable material does not substantially react with the resin mastic when injected into the first compartment. Another method of forming a resin grouting capsule includes: injecting a hardenable material into a first compartment of the capsule having catalyst mastic; wherein the hardenable material does not substantially react with the catalyst mastic when injected into the first compartment.
