Sistema de ventilación para labores subterráneas de la Empresa Produmin S.A.

Abstract

This research proposes: To implement a ventilation system to work inside the mine in the company PRODUMIN S.A., the study area is concentrated between the elevation 287,633 lower and upper one extends to 536,438. Located in Canton Camilo Ponce Enriquez, Azuay Province, the mine presents factors such as high temperature, permanent gas emission, dust generation and excess of moisture that causes an unsafe working environment and deficient performance in mining operations; it does not allow to comply the daily production. The method chosen was a ventilation system in series, mixed-suction plenum with the use of fans, turbines and exhaust ventilation sleeves. The transcendental part focused on the design of a ventilation system, taking into account each technical and safety factor to determine the requirement of air required for underground workings. Fieldwork and office work was performed collecting information, which led to the initiation of the research by creating a base line with which the system most suitable and cost-effective ventilation was designed to allow us to determine alternatives for a safe working environment in compliance with the rules that mining safety regulations of Ecuador requires. Later proposals were analyzed taking into account different technical-economic factors, which offset the need for clean air entering in a work front, making continuous checks and giving maintenance to the entire equipment involved in the ventilation system.

Key words: Ventilation system, impeller- suction method, mixed series method.
