Paper presented at the ISRM International Symposium - 10th Asian Rock Mechanics Symposium, October 29–November 3, 2018
Paper Number: ISRM-ARMS10-2018-097
... loading conditions, the failure modes of rockbolts in fields, the determination of bolt length and spacing, determination of the factor of safety, and the compatibility between support elements. Rock support elements are loaded dynamically owing to the energy release during rock excavation and statically...
