Edward Steed and Jason Emery, The evolution of primary cable support at Grasstree Mine, Proceedings of the 2020 Coal Operators' Conference, University of Wollongong - Mining Engineering, 12-14 February 2020, University of Wollongong, 57-73.


An increasing cover depth within a highly variable bedded and laminated roof, coupled with high level longwall retreat performance has required the evolution of cable support for development roadways at Grasstree Mine. This paper briefly addresses the evolution of cable bolting as primary support at Grasstree and captures in detail the theoretical and practical engineering applied to the most recent iteration of cable support, the Jumbo cable.
