Useful Knowledge You Must Know About Rock Bolt
As we all know, rock bolt is a basic component of coal mine tunnel support. It makes roadway surrounding rock reinforcement together, so surrounding rock supports itself. Rock bolt is now not only used for mining, but also for engineering technology, on the slope, tunnel, dam reinforcement.


Rock bolt reinforcement can be used in any excavation geometry, is simple and quick to apply, and is relatively cheap. The length of the rock bolt can be varied, which is depended on the reinforcement requirements. Rock bolt also has a lot of categories, such as ordinary self-drilling rock bolt, duplex coating rock bolt, expansion shell rock bolt, stainless self-drilling rock bolt, fiberglass rock bolt, and friction rock bolt. Each rock bolt has its inherent characteristics, we can choose the specific category according to our needs.

Which rock bolt system is the best to use depends on a variety of factors, which have to be considered in each individual case? For example, the self-drilling rock bolt is usually suitable for broken rock, loose soil and conditions that are difficult to drill holes, such as fracture zones. It helps to ensure anchoring effect in complex ground conditions and achieving a best construction result.
