What Are The Types Of Mining Anchor Rods

There are various types of mining anchor rods, each with its specific application scenarios and advantages. The following are some common types of mining anchor rods:
Metal anchor rod:
Reinforced anchor rod: made of steel bars, it has high strength and good rigidity, and is commonly used for supporting hard rocks.
Steel pipe anchor rod: using steel pipes as the main structure, suitable for supporting soft or semi soft rock. Steel pipe anchor rods can be grouted to increase the bonding force with the rock mass.
Steel wire anchor rod: Made of high-strength steel wire, it has a high tensile strength and is suitable for projects that need to withstand large tensile forces.
Resin anchor rod:
Resin anchor rod: usually used in combination with resin anchoring agent, the anchor rod is tightly bonded to the rock through the solidification of resin, and has the characteristics of fast installation and early bearing.
Glass fiber anchor rod:
Glass fiber anchor rod: made of glass fiber, it has high corrosion resistance and low density, and is suitable for humid or corrosive environments.
Pre stressing anchor rod:
Pre stressing anchor rod: Pre stressing the anchor rod before installation to improve its bearing capacity, commonly used for supporting large underground projects and important tunnels.
Hollow grouting anchor rod:
Hollow grouting anchor rod: With a hollow rod structure, it can be injected with cement slurry or other grouting materials to enhance the bonding force between the anchor rod and rock, suitable for various rock conditions.
Expansion shell anchor rod:
Expansion shell anchor rod: The expansion shell mechanism at the tail of the anchor rod forms close contact with the rock hole wall, thereby achieving the fixation and support function of the anchor rod.
Combination anchor rod:
Combination anchor rod: composed of multiple types of anchor rods, to fully utilize the advantages of various anchor rods and improve support effectiveness.
In addition to the common types of anchor rods mentioned above, there are also some special types of anchor rods, such as recyclable anchor rods, self-propelled anchor rods, etc., which are suitable for specific engineering conditions and requirements. When selecting mining anchor rods, it is necessary to consider the specific situation and geological conditions of the project, and comprehensively consider factors such as the strength, stiffness, durability, and construction convenience of the anchor rods to choose the most suitable anchor rod type.
