Split set bolt friction bolt
Price: 2
Friction bolt is a kind of underground mining roof bolts,also known as split set bolt.
It is an effective solution in underground mining roof supporting, tunnel construction.
It is a high-strength “C” shaped steel bolt with two parts, a tube and a matching domed bearing plate.
One end of the tube 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.
The rock bolt is an effective way to support the rock in underground mining and tunnel construction.
