Product Description
Mine rock split set bolt are rock bolts with only 2 parts, a tube and matching domed bearing plate. The high strength steel tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a welded ring flange to hold the bearing plate.
With the bearing plate in place, the tube is driven into a slightly smaller hole, using the same standard percussion drill that made the hole.
As the tube of the rock bolt slides into place, the full length of the slot narrows, causing radial pressure to be exerted against the rock over its full contact length.
