Project
Solution
Survey and set-out of retaining walls to define anchor installation.
Concrete coring and drilling from both below and above the pocket walls.
Installation, grouting, tensioning, and testing of cable bolts, with post-grouting to ensure integrity.
Use of radio-controlled mast drills mounted on excavators for below-wall drilling.
Rope access wagon drills and EWPs deployed for installation and testing in difficult access zones.
Project
Challenges
Urgent requirement to stabilise crusher pocket walls during mine development.
Limited access for drilling and installation around deep retaining structures.
Need for accurate survey, drilling, and testing to meet strict tolerances.
Requirement to complete all works safely under emergency program conditions.
Project
Overview
At Sino Iron, Australia’s largest magnetite mining and processing operation, emergency works were required to stabilise crusher pocket walls prior to the placement of new crushers. Earlier construction had left the walls unstable, requiring urgent rectification to allow the development program to proceed.
Geovert delivered a comprehensive scope including drilling, cable bolting, grouting, and testing, using a combination of specialist access methods to complete the works efficiently and safely.
