MAI SDA self-drilling anchors

Minova MAI SDA self-drilling anchors provide a unique bolting solution for unstable ground conditions such as sand, gravel, silt and clay, and in soft to medium fractured rock formations. For projects facing such ground conditions, MAI SDA self-drilling anchors should be considered as the most productive reinforcement solution.

The anchor rod features a hollow bore for flushing or simultaneous drilling and grouting, and has a left-hand rope thread for connection to standard drill tooling. It is manufactured from API standard heavy walling steel tubing, cold rolled to form a standard ISO rope thread profile. 

The rolling process refines the grain structure of the steel, increasing the yield strength, and producing a durable drill rod suitable for a range of applications. The sacrificial drill bit is the most crucial part of the anchoring system, and is responsible for the productivity of the installation. 

In order to improve on performance and cost efficiency, data is collected from projects around the world, and incorporated into the design with the aim to improve penetration rate and bit quality, and to reduce manufacturing costs. 

Minova MAI SDA self-drilling anchors are rigorously tested to ensure the best quality and reliability. MAI SDA self-drilling anchors also available in a hot dip galvanized version for corrosion protection and also as CE certified products. 

Main components MAI SDA self-drilling anchors consists of five basic components :
• A hollow rod
• One or more extension couplings which act as connectors between the rods
• A sacrificial drill bit
• A nut and
• A plate

Lokset® Resin Capsules

For over 30 years Minova Australia has lead the world in the development, manufacture and supply of resin capsules for rock bolting. Lokset® resin capsules are used primarily as an anchoring medium for rock bolts and cable bolts to provide roof (backs) and sidewall support to underground excavations. 

Minova’s Lokset® resin capsules are industry renowned for consistent quality and performance. With state of the art technical and manufacturing facilities, Minova Australia provides an extensive and flexible range of resin capsules to suit all types of bolting parameters including variations in equipment, environment and strata conditions. 

Lokset® resin capsules consist of a reinforced thixotropic polyester resin mastic in one compartment and organic peroxide catalyst separated by a physical barrier in the other compartment. The rotation of a rock bolt during installation ruptures the capsule, shreds the skin and mixes the two components causing a chemical reaction and transforming the resin mastic into a solid anchor. 

Over the past 30 years Minova has successfully introduced a range of revolutionary developments in resin capsules including the Lokset TOOSPEEDIE® (1993), Lokset® Long Tendon (1996), Lokset® X2 (2000) and more recently the Lokset Supamix® (2008) series. 

These developments have ensured that Australian mining and tunnelling industries continue to lead the world in safe, efficient and consistent resin bolting. Minova Australia resin capsule series are available in multiple configurations of length, double length combinations (X2), diameter, set time, set time combinations (TOOSPEEDIE) and viscosity.

Australian development and manufacture ensures 100% security of supply to every customer regardless of the location. Experienced technical and mining personnel are involved in the development, daily service and support of Minova’s range of Lokset® resin capsules.
