Mesh provides surface support coverage to loose rock between installed rock bolts in underground mining excavations. Multiple configurations of mesh is available including numerous sheet sizes, apertures, wire diameters and black or galvanised wire.
Ausro straps are yielding straps which allow the straps to yield under load conditions allowing better load distribution between bolts. Ausro straps are used in unstable ground conditions where seismic activity is present, to improve surface support and ensure better connection between the surface support and bolts.
Minova can supply a comprehensive range of plates for use with mesh.
Manufactured from high-strength steel and designed to help prevent loose material from falling between the roof bolt pattern and provide strength to your immediate roof.
Options of each plate type are available in numerous dimensions to suit any bolt type and diameter in the Minova range. Plates are available with or without a hanger loop in black steel or hot dip galvanised.
Further developing our plate range, our 200 mm Crown plate is a cost-effective alternative to Combi plates, reducing the number of plates required and providing improved strata support.
Friction bolts have been used internationally in mining for decades and are considered the simplest form of ground support available in metal mining. Compression of the high tensile steel "C" shape into a hole diameter smaller than the tube generates a load transfer from the steel to the rock. A steel ring is fixed to the collar end of the tube that will retain a plate on the installed tube to establish compressive force against rock.
Available in either black or hot dip galvanised. Variety of diameters (34 mm, 40 mm and 47 mm) and various lengths from 600 mm to 3,000 mm
Used in the development and production headings for immediate support with quick and easy installation.
In addition to a complete range of steel and chemical components, we can provide an extensive and complimentary range of accessories for steel strata support requirements.
Our range of accessories include:
• Strata Straps
• Mechanical Anchors
• Mine Nuts
• Pull Collars
