Mining Self Drilling Rock Bolt is one of the important support systems in coal mines. Its existence solves many problems in construction and can ensure the grouting effect under the chaotic geological conditions. So what are the functional advantages of mining self drilling rock bolt?

1. Mining self drilling rock bolt, which can self-drill the self-propelled mining anchor with both the functions of drill rod and rock bolt, eliminating the process of inserting the rock bolt into the drill rod to prevent rework due to hole collapse;

2. Mining self drilling rock bolt can be extended, with a variety of specifications, which is easy to use;

3. Compared with the solid with the same cross-sectional area, the hollow rod of the mining self drilling rock bolt has greater resistance, bending resistance and surface adhesion;

4. Mining self drilling rock bolt is hollow and can be grouted to the ground through mining anchors. General mining anchors are solid steel bars, while mining self drilling rock bolts are hollow steel pipes. The mining anchors are grouting pipes. The mortar enters from the end of the mining anchor, passes through the hollow web and the hollow drill bit, and then from the mining anchor. The front end overflows and comes back to the tail to grout, which can ensure that the ground bolts for filling mines can be used to turn over the open ground and consolidate the rock mass, and fully ensure the quality of grouting and anchoring. The stopper plug can ensure dense grouting and can reach a pressure of 1.5 ~ 2.0MPa;

5. Mining self drilling rock bolt is equipped with arched backing plates and nuts, which can apply prestress to the ground;

6. Can be drilled with ordinary drilling machinery, such as hand-held wind drill.

The above are the functional advantages of mining self drilling rock bolt. After more than 20 years of development, ZXSteelGroup has already possessed advanced bolt production experience. If you have any mining support products needs, please contact us.
