World"s biggest copper producer chooses Wassara™ for precision and work environment

The world"s biggest copper producer, Chilean mining company Codelco, is using Wassara for so-called preconditioning.


115 m-long upward holes with a diameter of 149 mm are drilled, and the rock is then fractured using high-pressure water, or by blasting.

The main advantage of the Wassara system is its ability to drill long, straight holes. The technology also enables a markedly improved work environment, with less drill dust and no oil mist.

The contractor, HRI, has modified a Tamrock Solo 606 rig. CMS has supplied feed cylinders and rod breakers. The rotation unit is from Atlas Copco, while Uraca supplied the high-pressure pump.

The implementation of Wassara at Codelco was made possible thanks to assistance provided by Gerencia Corporativa de Proyecto Minería Subterránea.

Result: Wassara is considered to have major potential, since the mine intends to drill even longer holes for preconditioning.
