Mining
In mining projects, the self-drilling anchor systems are generally composed of components such as hollow anchor rods, nuts, plates, couplers, centralizers, and drill bits. Depending on their specific applications, certain components may be added or removed.
This anchoring system integrates drilling, grouting, and anchoring functions into one, making it suitable for fractured and difficult-to-drill surrounding rock. It significantly improves construction efficiency, shortens the construction period, and reduces the overall construction cost. The hollow anchor rod can be arbitrarily cut and extended using couplers, making the self-drilling anchor bolt suitable for radial support in mine roadways. In mining support, the self-drilling anchor system can serve as systematic rock bolts, footproof bolts, roof bolts, invert bolts, forepoling pipes among others. It can replace reinforced anchor rods, ordinary hollow anchor rods, and small ductules, etc.
Common specifications include R25, R32, R38, R51.

Product Advantages
High Construction Efficiency
The self-drilling anchor system integrates drilling, grouting, and anchoring functions into one. In tunnels with difficult-to-drill formations, it can replace reinforced steel, ordinary hollow anchor rods, perforated grouting pipe, and other similar materials for construction, significantly enhancing construction efficiency and reducing construction costs.
Suitable for Construction in Spaces with Limited Clearance
The hollow anchor rod features full-length threads, allowing it to be cut at any position and extended using couplers. By utilizing small-sized drilling rigs, smooth construction can be carried out in small-section roadways.
Strong Adaptability
Conventional anchor rods have high requirements for drilling holes. If there is collapse or even debris inside the hole, it becomes difficult to insert them. In contrast, the self-drilling anchor bolt performs drilling and grouting in a single step without the need to withdraw the anchor rod, enabling normal construction even in fractured surrounding rock. It is applicable to various types of surrounding rock, demonstrating stronger adaptability.
