For some years, rock bolts have been used on a large scale by the Snowy· Mountains Authority for support of underground excavations during construction. Since 1958, they have been used to an increasing extent as permanent support.
The paper reviews, with particular regard to the new works commenced in 1961 and 1962, recent developments in rock bolt design, and in the practices and procedures of installation under conditions of rapid tunnel excavation. Where the bolt is to be part of the permanent rock support system, grouted deformed shank bolts are now standard; the structural advantages of these are described. The results of "pull-out" and other tests on bolts having various types of shank treatment are given.
