Pexgol pipe to transport effluents at 30°C / 86°F in an underground mine.

The Challenge

AngloGold had urgency in installing a new pumping line to remove effluents from the mine. Using traditional pipes could take up to two months to get the job done, considering all the preparation required to install such pipes. Furthermore, for AngloGold, using regular piping would mean putting its people in danger during the preparation to install the pipes and during installation itself.

Pexgol Solution

Using Pexgol allowed AngloGold to reduce the installation time by ten times, as a single continuous 120-meter-long pipe was used. Through an existing hole drilled on the mine the pipe was descended connecting its upper and lower parts. There was no need for people to be kept hanging at high heights to prepare any kind of structure to install the pipeline and no joints aside from the two extremes of the pipe were needed.
The reliability of Pexgol during the last years has motivated the client to continue with their material reliability improvements in other parts of the facility, and other sites.
It was an easy installation process, despite being the first time using Pexgol, and it was all done by AngloGold’s crew itself.
With a Volvo L90 loader and a JCB Loadall telescopic handler the crew completed the installation in 3 days.
