19. Hollow Injectable Cablebolts Summary Ground and rib fall accidents continue to plague the mining industry > mesh is a proven solution FlexKnotFlexKnot mesh was specifically designed for mining applications > higher strength, lighter, stiffer and corrosion protected Rolled mesh can reduce bolting cycle times and the new Fletcher handling system is being full-scale tested > improved ergonomics ~ faster cycle Rib control, Remedial work and Highwall stabilization have already proven to provide total surface control and easier to install > reduce total costs
