(1)Improvement Project Ventilation System Of Mine Achilla UEA Cia. Buenaventura SAA Mining (Peru)

摘要

The mining unit Julcani owned by the mining company Buenaventura S.A.A. Is located in the district of Ccochaccasa, province of Angaraes, department of Huancavelica in Peru; between 4200 and 4600 meters above sea level; it has one of its underground mining production areas in the Achilla mine where the cutting and backfill method is applied for the exploitation of veins. The results obtained from the simulation of the ventilation system with the use of Ventsim software were: After the simulation it was seen that with the construction of a Rise Climber shaft from the drift 590N (Gl. 529N) on the Nv. 610 arriving until the cross cut 388NW in the Nv. 460 is able to integrate levels 510 and 560 allowing the relocation of auxiliary fans inside the mine. The location and selection of an exhaust fan on the surface output of the Rise Climber 554-34 chimney. The recommended alternative is a 75,000CFM fan of 22.1 inches of pressure water column.
