ABSTRACT
New Concept Mining (NCM) has developed the Dynamic Impact Tester (DIT) capable of testing as many as 179 rock bolts in a period of six months, with no interruptions to mining operations. The limitations of the dynamic axial loading testing method are known, however, the DIT provides an efficient platform, on which a large number of tendon support systems can be compared under controlled conditions with increased agility. During the rapid development of new rock bolt products it is crucial to quantify the effects of high strain rates exerted by rock bursts on ground support systems. The DIT provides this capacity.
