In mining, a rock bolt is a long anchor bolt, for stabilizing rock excavations, which may be used in tunnels or rock cuts. This bolt is installed in a hole drilled into the rock, and is intended to improve the stability of the rock and prevent it from falling or collapsing.
One way to install rock bolts is through the use of a "rock split set bolt," which is a type of bolt that is designed to be used in situations where the rock is too hard or abrasive to be drilled using traditional methods. Instead of drilling a hole for the bolt, the rock split set bolt is inserted into a pre-existing crack or fissure in the rock and is then expanded using mechanical force, creating a secure anchor point.
There are several different types of rock split set bolts, each with its own unique features and benefits.
These bolts are made from a high-strength, corrosion-resistant material and are typically used in underground mining operations. They are installed using a resin cartridge, which is injected into the bolt and expands when it comes into contact with water, creating a secure anchor point.
Friction bolts are made from a flexible material, such as high-density polyethylene, and are designed to create a secure anchor point through friction alone. They are typically used in situations where the rock is too hard or abrasive to be drilled using traditional methods.

The primary role of rock bolts is to provide stability and support to rock excavations, such as tunnels and rock cuts. They are used to prevent rock from falling or collapsing, which can be especially important in underground mining operations where the risk of rockfall is high. Rock bolts are also used to stabilize slopes and prevent landslides, as well as to reinforce concrete structures.
In summary, the role of rock bolts, and specifically rock split set bolts, is to provide stability and support to rock excavations, preventing rockfall and improving the overall safety of the excavation site. These bolts are especially useful in situations where the rock is too hard or abrasive to be drilled using traditional methods, and are an essential part of many mining operations.
