Minova has developed this high-performance, cost effective bolting system to enhance resin mixing and minimize the potential for “glove fingering".
Glove fingering occurs when the film packaging within the cured resin is forced against the borehole wall to potentially interfere with the mechanical interlock of the resin and the rock mass. The offset head forces the bolt around the outside of the borehole wall, shredding the cartridge and increasing the mixing action.
Matched Bearing Plate systems and Minova resin capsules are available for all Minova Rebar Bolts.
Minova Reinforcing Steel Bar (Rebar) is manufactured to critical tolerances and standards to meet the day-to-day needs of our mining customers. Our comprehensive quality control program ensures that each Rebar Bolt order arrives at your site just as you have specified. And, because Minova is a world leader in manufacturing, you can be assured that we will be able to fill your orders quickly and efficiently, regardless of the size of the delivery requirement.
Minova Rebar Bolts are made from grade 40, 60 and 75 steel and can be manufactured as bendable products for low seam applications.
Cable Bolts incorporate much higher strengths than traditional bolts do, providing a much greater range of flexibility that adjust to the movement of the earth’s strata.
Cable Bolts are applicable where standard ground support is marginal or inadequate. Common application areas include: tail gates, bleeders, recovery rooms, set-up rooms, head gates, intersections and other mine areas where longevity and additional support is required.
