Self Drilling System

Our know-how is the result of over 40 years of experience in the production and global supply.

The system features a hollow bar, which is used as a drill string for drilling either with water flush, air flush or cement grout flush.

All system components are rigorously tested according to stringent factory standards and ISO 9001 to ensure that the specifications are met. The sacrificial drill bit significantly enhances the productivity of the installation process. In order to improve performance and cost-effectiveness, project data are being collected from around the world.

Continuous optimisation of our drill bits is a primary concern to further improve the penetration rate and bit quality while at the same time reducing manufacturing costs. For improved corrosion resistance, Self Drilling Anchor components are either hot dip galvanised or fitted with a TwinCoat coating (hot-dip galvanisation with an additional dual epoxy coating).

Lokset™ Products

We have manufactured Lokset resin capsules since the late 1960's and are the leading supplier and innovator in this field. Our development and manufacturing ensures security of supply, service and support.

The Lokset system consists of an easily handled cartridge, containing a highly reinforced polyester resin component, together with its catalyst, in accurately measured quantities. The rotation of the 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.

The Lokset resin capsule series is available in multiple configurations of single/double length combinations, diameter, set time, set time combinations, viscosity and shelf life.

 

Did you know?

The oldest reference Minova has for Lokset® resin anchors was the strengthening of the London Heathrow Airport road access tunnel in 1963 to allow heavy jets to land. Since then there have been numerous applications across the world in mining applications, highway tunnels, civil applications and a submarine base.

Plates / Straps Type W

SP-220, SP-270, and SP-320 W-straps have a similar design. They differ only in terms of steel sheet thickness and section width. There are deformations for added strength and appropriately spaced holes along the straps (round or oval as requested). It is possible to connect two or more mats cross wisely or length wisely.

In terms of a range of application and production method the mats can be divided into the following types:

  • W – strap type SPs
  • W – strap type SPo
  • W – strap type SPp

Tekblend

A one component material which after mixing at the site of application with the appropriate amount of water (water/powder ratio of 1:1 to 4:1) sets to become a durable concrete material.

The material, upon exiting the pump, is liquid and thus it is able to fill any roughness and gaps. Tekblend gels after about 3 minutes depending on the preparation method.

Tekblend is commonly applied in:

  - building of monolithic packs for the protection of longwall galleries

  - building of ventilation and explosion resistant seals

  - building of isolation and backfill walls

  - filling voids (cavities) above mining excavation roof support

  - eliminating voids outside of mining excavation roof support

  - filling backfill voids

  - sealing of galleries

Tekcrete™ Fast M

Fibre reinforced, this product offers strengths over 55 MPa and can be used in conventional, dry-process shotcrete equipment. It is ideal where immediate structural strength is required.

Tekcrete™ Fast M was developed in response to customer demand for a shotcrete with effectively immediate strength on application. The product can be used with or without steel or polymer mesh, although the mesh will provide additional tensile and flexural strength. Binding broken strata together for better structural integrity, Tekcrete™ Fast M can be used anywhere in a mine where conventional shotcrete is used and as with any coating or sealant.
