‍

Application description “Installation of survey pegs by surveyors”

Application done daily as this is a critical procedure of all underground mining operations

Surveyor drills 10mm hole into hang wall and inserts small wooden block

Spade is driven into wooden block while keeping ‘tally ‘in place  

‍

‍

The “challenge”

Need to drill multiple holes, overhead – excessive dust exposure

Spades get pulled out of wooden block by miners' loco’s or machinery - which forces surveyor to reinstall survey pegs

Waste of time/ productivity and mining production is affected

‍

‍

The “solution”

TE 4-A22 / TE 6-A22 Drill

TE DRS-4-A / TE DRS-6-A Dust Removal system

TE CX insert selection for all needs and the application on hand

Tie Wire Anchor (M6 x 30 HHDCA)

Customer “benefits”

Drilling 6mm hole instead of 10mm hole as well as shallower embedment depth reduces installation time 

Hilti anchor solution ensures the peg is very difficult to remove making a much more long-term installation  

A much safer, faster and reliable method for surveyors
