The Challenge
The Ojos del Salado mine (Lundin Mining) required the installation of a line for the drainage of high pressure water from the lower mine level, through the vertical ventilation chimney, with a height of 30 meters.
Primarily the client faced time problems on one hand and on the other hand needed the pipeline to be installed in the shortest time possible, without interfering with the mine’s operation.
Pexgol Solution
It was decided to install a 600 m line of Pexgol 160 mm (6″) class 24 pipe for drainage due to its long length supply format, ease of installation, flexibility contributing to easy accommodation into the curves of the mine interior. Furthermore, due to limited installation times operation stops could be avoided.
It took only 2 days to uncoil and assemble the pipe. For reasons of convenience and at the request of the Prevention Department, the pipeline was placed in sections of 150 meters, since it had to be pulled a 5 km long ramp from the mine interior to the installation point.
Under the same conditions when installing HDPE pipeline, it would have taken about 1 week only to prepare the sections before installing them inside the mine and furthermore only shorter sections could have been installed due to the rigidity of the material.
