History of the sprayed concrete lining method-part II: Milestones up to the 1960s
In this part, first the origin and development of rock anchors are described. Their history began with a patent application in 1913 in Germany. The breakthrough in application came, however, only in the 1940s from the American mining industry. The first application of systematic rock bolting in a tunnel was the diversion tunnel for the Keyhole Dam in the USA in 1950. This paper describes numerous examples of civil engineering work world-wide with early application of rock bolting. It is shown how the combined application of the new support elements-steel arch, sprayed concrete and anchors has led to the 'sprayed concrete lining' method in the 1950s. In concluding, it is demonstrated that the so-called 'New Austrian Tunnelling' Method (NATM), which has been propagated since 1963, is in many respects borrowed and has created much confusion amongst professional engineers by dint of its pseudo-scientific basis.
