Split Set

Split sets / friction anchors have been used as a primary roof support in the underground mining environment for many years. The anchor consists of an open seamed high tensile Supraform S420 steel tube with a face plate. One end is tapered for easy insertion into a pre-drilled hole. It is installed by driving the assembly into a marginally smaller hole than the split sets diameter and the welded steel ring then provides the necessary support to hold the washer plate in place. The set then uses friction to anchor itself along the whole length of the bolt by relying on the radial spring force generated through compression of the tube. Split set technology is used worldwide by many mines for an extensive variety of mining applications.

Key Advantages of using Split Sets

Fast and easy installation
Full length support
Effective support at any angle
Cost effective
Axial and radial support
No torqueing or re-torqueing
No special equipment is required
Improved rock stability

Sizes Available
Split set friction anchors are available in 36mm, 38mm, 39mm, 47mm diameters in a variety of lengths to suit the application of the mine. Depending on the strength and corrosion requirements, The domed bearing washer plates are available in 150mm x 150mm x 4mm.
