ABSTRACT:
A dual stage dynamic rock stabilizing fixture for insertion in a bore hole in a geologic structure, the fixture combining a dynamic compressible plastic formable material and an activatable bonding material in various cooperating arrangements which upon insertion of an anchor rod will perform an initial stabilization of the rock structure through the compression of the formable material by the anchor rod in advance of a subsequent stabilization effect upon setting up of the activatable bonding material through mixing action of a suitable surface configuration on the anchor rod. The fixtures hereof are designed to carry out the steps of a method of inserting the combined formable material and the bonding material into a bore hole, and using an anchor rod to establish a rapid first stage of rock stabilization through the formable material which creates a dynamic support and a second stage of rock stabilization from the activatable bonding material which creates a high modulus stiff anchor.
