Abstract
Actualmente, las empresas mineras se enfocan en optimizar su rentabilidad desarrollando proyectos que reduzcan costos, mejoren la seguridad y mantengan la producción sin afectar negativamente los procesos. En la CIA. Minera Lincuna que desarrolla procesos de explotación subterránea en la zona Coturcan, se ha implementado un proyecto con el objetivo de mejorar el sistema de ventilación y reducir sus costos mediante la construcción de la chimenea Alimak. Este proyecto responde a las deficiencias existentes, particularmente en el nivel 10, donde el caudal de aire es insuficiente. Además, se ha considerado que los ventiladores instalados en la zona Coturcan generan elevados costos de mantenimiento y consumo eléctrico.
Finalmente, la construcción de la chimenea Alimak AK-02 mejoró significativamente el sistema de ventilación, alcanzando una cobertura del 88% al 115%. Esto permitió un aumento en el porcentaje de oxígeno y una reducción de la temperatura en las labores del nivel 10 de la zona Coturcan. El costo total de la construcción de la chimenea Alimak AK-02 fue de $552,326.32, con un tiempo de ejecución de 7 meses. Además, se logró reducir los costos de ventilación mensuales de $53,210.41 a $36,195.01, lo que representa un ahorro de $17,015.40 al mes, equivalente a un 32%. También se disminuyó el riesgo de accidentes por gaseamiento en el interior de la mina.
Currently, mining companies focus on optimizing their profitability by developing projects that reduce costs, improve safety and maintain production without negatively affecting processes. At the CIA. Minera Lincuna, which develops underground exploitation processes in the Coturcan area, has implemented a project with the objective of improving the ventilation system and reducing costs through the construction of an Alimak chimney. This project responds to existing deficiencies, particularly at level 10, where the air flow is insufficient. Furthermore, it has been considered that the fans installed in the Coturcan area generate high maintenance costs and electricity consumption. Finally, the construction of the Alimak AK-02 chimney significantly improved the ventilation system, reaching a coverage of 88% to 115%. This allowed an increase in the percentage of oxygen and a reduction in temperature in the work at level 10 in the Coturcan zone. The total cost of construction of the Alimak AK-02 chimney was $552,326.32, with a completion time of 7 months. In addition, monthly ventilation costs were reduced from $53,210.41 a $36,195.01, which represents a saving of $17,015.40 per month, equivalent to 32%. The risk of accidents due to gassing inside the mine was also reduced.
