Minova’s Coal Bolt is a fully encapsulated rock bolt engineered to keep underground coal headings stable and productive across regions. We combine a rolled thread with a ribbed surface to drive efficient resin wet‑out and dependable load transfer, while matched washers and a drive nut support consistent installation. Used with our Lokset® resin capsules, rotation mixes the cartridge to create a rapid, interlocked anchor; selectable setting speeds allow you to anchor, grout and tension in a single operation to suit local cycles and equipment. The range covers multiple configurations and steel grades, including high‑tensile options for areas prone to stress corrosion cracking. To complete the system, choose compatible dome, combi or crown plates and protective coatings, including hot‑dip galvanised finishes, to extend service life. Minova’s coal bolts meet all regional steel specifications and standards.
