The "rock bolting" is one of the most commonly used systems for rock mass stabilization, especially in tunneling and mining
industry.
We sell high resistance continuously threaded bars, which offer following
advantages:
-
They may be used with a sacrificial drill bit
-
They may be used with mechanical anchorage
-
They provide a continuous closed circuit for high pressure grout injection for pumping thixotropic grout mixtures
-
They may be cut and coupled at site to get neces-sary lengths
-
Lower weight, i.e.: lower handling costs and easier setting operations
-
Smaller diameter bars can be used under same lo-ad, due to extraordinary steel mechanical proper-ties,i.e.: lower cost of the structure components (bars, couplings, bits), easier drilling and setting, reduced mixture quantity, smaller rigs can be used.
