Paper presented at the 4th North American Rock Mechanics Symposium, July 31–August 3, 2000
Paper Number: ARMA-2000-0633
... ABSTRACT ABSTRACT: Instrumented cable bolt support [SMART - Stretch Measurement for Assessment of Reinforcement Tension - cables] was developed in Canada [Canadian Patent #2,200,834] and has been in use for the past three years. These instruments have achieved wide acceptance in the Canadian...

Paper Number: ARMA-2000-0641
... ABSTRACT ABSTRACT: Cement-based grouting technique is normally applied to the crown area of the shallow tunnel so that the instant reinforcement and the long-term stability of a tunnel are assured. However, the assessment of the reinforcement effect has not been fully understood so far...

Paper presented at the 4th North American Rock Mechanics Symposium, July 31–August 3, 2000
Paper Number: ARMA-2000-0465
... ABSTRACT ABSTRACT: The empirical scaled span approach for assessing surface crown pillar stability has been in use for over a decade. In this time it has been widely applied for dimensioning new pillars and for assessing the stability of old, often abandoned crowns. Based on updated knowledge...

Paper Number: ARMA-96-1951
... provided insights into the behaviour of the rockmass surrounding stopes at a global scale but, on the whole, provide at most a crude assessment of the local stability of the hangingwalll in the face area. The discontinuum model used to investigate aspects of support rockmass interaction is briefly...
