Anchorage behaviour of underground rockbolts

A new type of rockbolting system, the self drilling rockbolt, has been studied in order to develop a "single pass" bolt for use in rockbolt installation in underground engineering. This single pass bolt is to form the basis of a Rapid Face Bolting (selfdrilling bolt) system which will reduce the amount of time spent in securing the roof during the operation of a continuous miner in the development of a panel. The research consists of two parts. Part one: simulation tests in the laboratory. Part two: finite element calculations.
