Rock bolting: Theory and application in mining and underground construction Proceedings of the international symposium, Abisko, Sweden, 28 August-2 September 1983

Rock bolts today represent the dominant support system in mines and underground structures. Some results and experiences are discussed to give a better understanding of the strength of individual rock bolts and systems of bolts, and the interaction between bolts and rock masses of various types. Topics covered are as follows: rock bolting in theory and experiments; design principles and experience; and ground control and instrumentation: cable bolting
