UniPass Bolting

LEADING-EDGE TECHNOLOGY.

UniPass bolting technology combines leading-edge and high-quality, high-strength products to make rock bolting safer, faster and more efficient.

 

► Next Generation Bolting
UniPass bolting combines our static, yielding and dynamic hollow bolts and Carbothix bulk resins to provide an all-in-one bolting system that has been engineered to suit the most demanding requirements of underground mining. The immediate bonding of the resin makes it possible to load the bolts without leaving the borehole, dramatically increasing bolting speed and worker safety.

► Installation Flexibility
The UniPass system can be installed in a one step operation by using our self-drilling bolts. The system can also be installed in pre-drilled holes (two step process). UniPass is adaptable to varying ambient temperatures, humidity and ground conditions.

► Automating Mines
The UniPass bolting system has been designed with semi- or full- automation of ground support installation in mind.

Dynamic Rock Bolt

The UniPass dynamic bolt is intended for use in dynamic conditions and in areas where there is a risk of rock burst.

The bolt has three sections; a threaded bond section, a smooth yielding section and a threaded bond section.

The yielding section comprises a smooth ductile steel tube, which easily debonds from the grout and absorbs energy during a dynamic event. The bond section at the near end is optional and can be as short as 200 mm, providing sufficient space for the plate and the nut.

The bolt can be installed in self drilling mode using a sacrificial drill bit (one step method) with the drill bit welded to the bolt, providing optimal bonding and reduced grout consumption. The bolt can also be installed in pre-drilled holes.

The grouting agent (CarboThix resin) is injected through the central hollow section of the bolt into the borehole and fills the annulus between the bolt and the borehole wall.

Static Rock Bolt

The UniPass static bolt is intended for use in static rock conditions.

The bolt comprises a fully threaded hollow bar.

The bolt can be installed in self drilling mode using a sacrificial drill bit (one step method) with the drill bit welded to the bolt, providing optimal bonding and reduced grout consumption. The bolt can also be installed in pre-drilled holes.

The grouting agent (CarboThix resin) is injected through the central hollow section of the bolt into the borehole and fills the annulus between the bolt and the borehole wall.

Carbothix®

Two component grouting resin for cable bolt anchoring and self drilling bolts. An instantly thickening, fast curing, two component silicate resin for high strength bonding of solid bolts and cable anchors. The final mixture thickens very quickly to form a tough, interpenetrating non porous elastic silicate. This minimises leakage from the bolt hole, displacing drilling water helping ensure full encapsulation.

Carbothix has been designed especially for use with our range of UniPass dynamic and static rock bolts. Tested in Australian conditions, Carbothix allows for improved rock bolting productivity.
