Split set mining ground support product

what is welded wire mesh?

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.

Split-Set Rock Bolt: Used to strengthen mine roadway, bridge, tunnel, track, slope protection and other support, often used in iron ore, gold.

1. The raw material is high strength alloy strip steel

2. Easiest to install 3. No anchoring agent required

4. Has a high alkali resistance tensile strength

5. The friction force of bolt on rock mass is large 6. Equipped with high strength pallet, pallet force is uniform

How The Split Set Rock Bolt Work? Design: A Split Set consists of a high-strength steel tube, typically around 1.5 to 2.0 meters in length, with longitudinal slots or splits along its length. These splits allow the tube to compress radially when inserted into a drilled hole.

Installation: The Split Set is installed by inserting it into a pre-drilled hole in the rock or excavation face. As the Split Set is pushed into the hole, the rock's radial pressure causes the tube to compress, exerting outward pressure against the walls of the hole. Anchoring: Once fully inserted, the Split Set locks itself into place within the hole due to the radial pressure exerted by the compressed tube. This creates frictional resistance between the Split Set and the surrounding rock mass, anchoring the unstable rock formation and providing reinforcement. Support: The Split Set stabilizes the rock mass by redistributing stresses and increasing its overall strength. It helps prevent potential collapses, rockfalls, or other instability events by providing support and containment. Compatibility: Split Sets are often used in conjunction with other ground support systems such as mesh, shotcrete, or cable bolts to provide comprehensive reinforcement and stability in challenging geological conditions.

Friction Bolt Underground Mining

01.

First, lay the steel mesh sheet along the top of the roadway, determine the hole position of the bolt according to the construction requirements, and then drill the hole with a drill pipe 1-2 cm larger than the diameter of the pipe seam bolt

02.

After drilling, use pressure air to clean the rock powder in the hole to reduce the stone sticking.
