Ⅰ. Introduction

Split Set Bolt, also called Split Set Stabilizer or Friction Bolt, is an indispensable advanced material in underground mine support. Split anchors are a common support product and are used as advanced materials for roof support in projects such as underground copper or gold mining.

Ⅱ. Learn more about Friction Anchor Bolt

1. Definition and composition

Friction bolts have been used internationally for decades and are considered the simplest form of ground support in metal mining. High-strength "C"-shaped steel is compressed into a hole smaller in diameter than the tube, creating load transfer from the steel to the rock. A steel ring is secured to the coupling end of the casing, which will secure a plate to the installed casing to establish compression against the rock. Regarding material and surface treatment, black and hot-dip galvanized are available. The components of the friction bolt are also very simple. It consists of a welded ring, a tray and a hollow rod, forming a set of supporting materials.

2. Characteristics of the anchor itself

① Increase the contact surface to provide higher pull-out load.

② Provide friction support on the ground

③ Installed with handheld or mechanized equipment

④ Simple installation steps

⑤ Has high shear strength and tensile strength.

⑥ With high-strength pallet

Ⅲ. How to assemble friction bolts?

A pull collar fixing at the ring end enables load testing during the bolt installation. The tapered end of friction bolt can be easily inserted into the drilled holes. Friction bolt can be installed with either hand held or mechanized equipment, such as a jackdrill, a stopper, a roof bolting jumbo, or any other type of drill.

Ⅳ. What are the advantages of friction bolts?

1. Made of high-strength steel pipe, it is a new type of anchor.

2. Optional galvanized and stainless steel materials.

3. Suitable for mining support and other fields to improve rock stability and safety.

4. Versatility: Whether it is mining, tunneling or other underground projects, friction anchors can adapt to various complex geological conditions.

5. Easy installation: The installation process is simple, saving time and labor costs as well as the cost of composite materials. Simplicity of installation ensures efficiency without compromising performance. Friction bolts are therefore a cost-effective option.

6. Immediate load-carrying capacity: Friction bolts provide immediate load-carrying capacity after installation due to the friction generated between the bolt and the surrounding rock.

7. Reduced risk of accidents: Friction bolts are less likely to cause accidents because they don’t need to be hammered into place. This reduces the risk of rock fracture and reduces worker exposure to vibration and dust.
