The Challenge
Lundin Mining at Calendaria Norte Mine had to install a drainage line for its underground mine, where the main challenge was to pass it through the main ramp of the mine, which is only available once a month during its maintenance (since the operation of the mine cannot be stopped).
Pexgol Solution
The client decided to install 3,000 meters of Pexgol pipe that was supplied in five coils of 600 meters each. Two main maintenances were scheduled, where three coils per day (1800 meters) were unrolled and installed.
Cross-linked polyethylene was chosen because of:
- Its long-length supply format.
- Ease of installation, thanks to the flexibility of the pipe that was easy to accommodate in the curves of the interior of the mine.
- Limited installation times to avoid stopping the mining operation.
Installation was quick and easy, uncoiling the full length of the pipeline and then dragging it into the mine.
