It´s about a drainage mechanism that uses a pumping system from the bottom of the mine to evacuate the water.

HighService Engineering and Construction (HS) won a new contract called “Dewatering, Installation of mine bottom drainage system” at Minera Los Pelambres (MLP), owned by Antofagasta Minerals (AMSA).

The initiative contemplates the implementation of a water management system from the bottom of the mine to a distribution chamber, using a water impulse system called Dewatering.

“The system is based on three vertical centrifugal pumps that activate a pumping mechanism in ponds to evacuate larger floods or empty the lagoon, and change the extraction bottom of the mine,” explains Israel González, HighService Engineering & Construction General Manager.

The company’s work will consist in the construction of a drive system for the evacuation of water accumulated from the bottom of the mine, to an intermediate tank, to operate in the new growth scenario of the mine.

The project will last for 7 months and the most important disciplines for its execution are mechanical and piping.

Minera Los Pelambres is an open pit mine mainly made of copper and molybdenum concentrate, located in the Andes mountain range, Salamanca district, in the IV Region of Coquimbo, between 3,000 and 3,500 meters above sea level.
