Patent

CA 2470212

This invention is designed to secure loose rock formations in mining of all descriptions (ie: underground, open pit, tunneling, rock cuts, etc.) as well as anchor any and all objects to rock surfaces, in any and all positions. The anchor consists of the main body that is of wedged design, threaded at the superior end to receive the bolt to be anchored. The outer shells are of a corresponding design, angled with opposing configurations to create a lateral movement against the bore hole when force from the rod is applied. The main body and shells interlock at their base. The shells are joined by a bail that crosses over the superior end of the main body. The bail is secured to the rod and centers the shells around the main body. The resin harness is located at the superior end of the main body. When the anchor is separated, a lance punctures the spring loaded resin capsule forcing the resin into the anchoring area.
