Case Study
Vertical Cable Installation Projects
CASE STUDY:
NORTHERN GOLDFIELDS
A northern Goldfields mine site required an electrical upgrade to supply power direct to an underground crusher circuit. Murray Engineering designed, constructed and installed a vertical cable installation system to deliver the required power upgrade without interruption to normal mining activities. This method saved the client hundreds of thousands of dollars and was installed and commissioned in just nine days on site.
DETAILS AT A GLANCE
- 1500m cable length and 28 tonne weight
- 11,000V 350A electrical supply
- Suspended from the surface only
- 11kV switchgear enclosure included
- Unique cable clamps designed specifically for the job to reduce borehole size by 30%
- This is the second vertical cable install completed by Murray Engineering at the client’s mine site
CHALLENGE & SOLUTION:
The mine site is the deepest operating mechanised mine in Australia. The client recognised that this would result in a huge cost to install electrical cable via traditional methods (i.e. decline and service hole). Murray Engineering was engaged to install a second vertical cable from the surface, with zero interruptions to daily mining operations or ore haulage. The Murray Engineering team designed and installed concrete footings, a winch assembly, sheave assembly and final support structure. Murray also developed the installation methodology, and commissioned the project on site, including civil works.
