Abstract
La preparación minera es la mayor restricción al fijar la tasa de producción en minería subterránea. No es la excepción en block caving, de hecho, aproximadamente la mitad de su costo de operación se debe a la preparación de la mina.
Al estudiar a fondo el costo de la preparación minera en el método block caving, se puede observar que la mayor parte del costo y tiempo de preparación está relacionado con la construcción de pavimento y otras instalaciones especiales en los puntos de extracción. Debido a esto, la siguiente memoria de titulación presenta un diseño de preparación de block caving, que reduce la construcción de concreto al mínimo buscando una reducción significativa del tiempo y costo de la preparación minera.
Mining preparation is usually the main restriction when fixing the rate of production in underground mining. Block caving is not an exception, in fact, approximately one half of its operating cost is due to mine preparation. Studying deeply the mining preparation cost in block caving method, it may be observed that most of the time and the cost of preparation is spent on construction of concrete pavement and other special installations at drawpoints. This work presents a design on block caving preparation, that reduces the concrete construction to a minimum looking a significative reduction of time and cost of mine preparation.
