We have the answers to all your roof support questions. Why do miners build roof supports? Roof supports are essential in all mines to keep workers safe from underground mining hazards. The system provides constant resistance to keep key blocks in place, protecting the hanging roof’s integrity during blasting. What
All about resin bolts Resin bolt assemblies comprise the stud, nut, bearing plate washer, and various accessories and modifications that can be configured to meet specific installation and rock support needs. Cartridge resin bolts vs pumpable resin bolts Rock bolts are frequently used in deep underground mining and tunnelling to
The type of rock bolt you choose depends on the specific application. For example, weight, location, and budget play a role in your selection. Grout-anchored rock bolts A grouted rock bolt is a steel threaded bar, also known as a rebar bolt. After drilling and inserting the steel rock bolts,
Occasionally, using a traditional expanding plug, screw, or anchor fixing in a breakable substance like concrete, brick, or cement can cause splitting or cracking. This is frequently the case near the material’s edge, affecting the substrate’s strength, efficiency, and aesthetics. A resin anchor bolt can solve this problem. These resin
Installing resin bolts Resin bolts comprise a two-part polyester resin-catalyst capsule and a steel bar with a plate and nut. Resin bolts are used in place of mechanical bolts in areas that require a higher strength fixing. This is how these bolts should be installed. First, it’s critical to drill
Load indicator washers, also known as direct tension indicator (DTI) washers, are used to establish that a structural bolt connection is installed to the precise tension. Load indicating washers have been around since the 1960s and are extremely accurate. Their raised protrusions will collapse when the bolt is tightened to
Mining roof bolt basics Roof bolting is a method of inserting metal rods into a mine roof to prevent roof collapse. The introduction of mining roof bolts in the 1940s has resulted in the standardisation of roof support systems that could not be destroyed by blasting. As a result, mining
