Split Set Bolt

Split Set Rock Bolts and Friction Bolts Work:

Split Sets 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.

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.

Mining and Ground Support:

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.
