摘要

Open Pit mining process that involves the formation of vertical slopes or Banks, which has the characteristic of reducing the Gangue / mineral ratio because it comprises the following stages, to develop a First Bank to reach 25% of the final height of the slope VERTIC You want to build, immediately under the First Bank,We proceed to develop a Second Bank to reach 50% of the final Height, immediately under the Second Bank, build the Third Bank up to 75% of the height of the vertical Slope End, and after the removal of the material that allowed the Construction of the Third Bank Fourth is to build a Bank up to 100% of the height of the vertical Slope.
