1. Ultra high strength, high impact energy rock bolt —— Impact absorbing energy advanced world levels
Normal 600MPa grade rock bolt’s impact absorbing energy Akv is around 60J, but our LT products high strength rock bolt’s impact absorbing energy Akv ≥180J， which is very competitive worldwide.
2. Ensure the security og mining, reduce mine accidents possibilities and casualties.
LT rock bolt products have the result of CCII(China Coal Information Research Institute) testing, Lu’an Group and JAMG feedback after using LT 2000 tons super high strength heat treatment rock bolt for underground tunnel roof proof support. LT rock bolt have significantly improved the reliability of tunnel and mining roof & roadway support, no rock bolt breakings or mining issues occurred, which means LT products solved the problem of some breaking and broken issues in difficult and complicated condition, ensuring mining and tunnel a security operation environment.
3. Increased mine resource recovery rate
LT use super high strength heat treating anchor rock bolt to narrow the width of protective coal pillar. Each protective coal pillar is able to mine coal 50% more after using LT anchor rock bolt.
4. Reduce maintainance costs
our LT super high strength anchor rock bolt can control tunnel deformation, which will be able to reduce maintainance costs for tunnels, 45~110 USD per meter reduced, 60 USD in average.
