Abstract

Sociedad Minera El Brocal is engaged in the exploration, development, mining and processing of polymetallic minerals. 

In order to increase production, we sought to maximize the recovery of the pillars left after the mining of primary pits, using ITH equipment with Wassara system, which allows to have greater reach and less deviation than the mechanisms with top hammer.
