MODEL STUDY OF RIB-IN-ROC PRE-REINFORCEMENT FOR LARGE UNDERGROUND OPENINGS

The objective of the research described in this report is to develop a fundamental understanding of the rib-in-roc method and of the mechanisms involved and its quantitative contribution to permanent as well as to immediate stabilization of a large underground opening. This is the final report of a two and a half year research program carried out at the University of Luleaa, Department of Rock Mechanics. This report presents a physical model study on the effectiveness of the rib-in-roc method for the stabilizing of large underground openings. In this study the approach to the dimensional analysis and the use of it is slightly different from previous works. A stress has been put upon pi-numbers in the dimensional analysis such that more information is exploited than is usual in rock model studies. An effort has also been made to synthesize all previous and current notions towards the creation of a practical working system of the so called rib-in-roc method. (TRRL)
