Shandong Juye Mining Technology Co.,Ltd is a professional manufacturer for  Mining and ground support products.

Split Sets friction sabilizer bolts is a bolt for temporary stabilisation and consist of a tube and 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. The tube is driven into a slightly smaller hole, using the same standard percussion drill that made the hole. The slot narrows, causing radial pressure to be exerted against the rock over its full contact length.

the bolts can be galvanised for corrosion protection.

Products Specification:

Split Set Rock Bolts and Friction Bolts Work:

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.

 give you a choice of tube and plate sizes.

Quality Standards:

Split Set rock bolts (friction bolts) are manufactured to a highest standard of quality. Rigid standards of quality are achieved by exhaustive quality control, testing and inspection procedures. Detailed drawings specify materials, dimensions, and tolerances. Every Split Set is identified with model number, length, factory, rolling date, and heat lot of the steel.

Split Set friction rock stabilizers are used for underground or surface support in many applications:

1. Underground Mine Roof Support & Mine Roof Bolting

      2. Ground Support for Tunnels and Other Excavations

3. Ground Support for Surface Jobs

Varied Applications for Split Set Rock Bolt Systems where Stabilize, Hold and Control are Necessary:

Water tunnels     Shaft walls     Sewage tunnels     Underground storage caverns       Road tunnels

Pipe and ventilation ducts   Conveyor belts   Trolley wires    Surface excavation slopes     Highway cuts

 Split Set Rock stabilizers are an easy solution to your ground support, mine roof support and other stabilizing, holding, or anchoring problems. They are cost effective and simple to install.
