Abstract
En las operaciones de minería subterránea, el uso de cargadores y camiones articulados de bajo perfil son prácticamente un estándar de diseño, siendo en la actualidad los equipos diésel los que dominan el mercado, pese a que desde la década de los 60, se ha intentado introducir equipos eléctricos debido a su menor impacto ambiental y mayor confort para operadores.
La preferencia generalizada de uso de equipos diésel sobre sus competidores eléctricos se debe principalmente a su menor costo de adquisición y mayor flexibilidad de desplazamiento en interior mina. El desplazamiento de equipos eléctricos está severamente limitado a las zonas de la mina en que existe una red física de energía eléctrica donde conectarse mediante carretes de cable o troles.
La reciente tecnología de accionamiento eléctrico usando baterías de litio incorporada a los equipos de carguío y transporte subterráneos, ha permitido eliminar las limitaciones de flexibilidad de desplazamiento de los antiguos equipos eléctricos manteniendo sus ventajas.
En el presente trabajo de titulación se analiza el efecto de introducir equipos de carguío y transporte subterráneo accionados por baterías de litio, en vez de equipos con accionamiento diésel, respecto de los requerimientos de instalaciones auxiliares para la operación, de energía de ventilación y de costos de adquisición y mantención
In underground mining operations, the use of loaders and low-profile articulated trucks are practically a design standard, with diesel equipment currently dominating the market, despite the fact that since the 1960s, attempts have been made to introduce electrical equipment due to its lower environmental impact and greater comfort for operators. The general preference for the use of diesel equipment over its electric conductors is mainly due to its lower acquisition cost and greater flexibility of movement inside the mine. The movement of electrical equipment is severely limited to the areas of the mine where there is a physical network of electrical energy where they are connected by means of cable reels or trolleys. The recent electric drive technology using lithium batteries incorporated into underground loading and transport equipment has made it possible to eliminate the displacement flexibility limitations of the old electric equipment while maintaining its advantages. In the present titling work, the effect of introducing underground transport and loading equipment powered by lithium batteries, instead of diesel-powered equipment, is analyzed with respect to the requirements of auxiliary installations for the operation, ventilation energy and costs. acquisition and maintenance
