Diseño de explotación por corte y relleno ascendente de la Veta Mary en la Empresa Produmisa, sector Bella Rica

Abstract

This research proposes: Design an operating method according to the shape and distribution of the ore body maximizing the extraction and processing of mineral in the company Produmin SA, in the parish Camilo Ponce Enriquez, Canton Ponce Enriquez, Azuay Province; initially using a bibliographic research and geological reports and mine planning. Later fieldwork measurements and sampling for later in cabinet making such calculations are executed; obtaining a hydrothermal reservoir, filoneano by filling cracks with a preferential direction NS with an average dip of 60 ° SE, embedded in rocks of andesitic intermediate composition, with basic RMR (Rock Mass Ratting) of 71 and a rock Type II according to the classification table geomechanics Bieniawski 1979; a mineral reserve of 2404.09 Ton, considered with 91% recovery. Preparation costs, mining, operating and cleaning the block totaling USD. 114.31 / Ton, considering the volume of reserves will have an investment of US $ / 286.856,01. With a utility or U $ 3,451,984.76. It concluded that the system of exploitation by cut and fill to implement, is a method that is applicable in vein-type bodies that have a greater dip to 50 ° dip, low power, gives us a very high recovery (91%), it is highly selective, allowing us to work on deposits of high grade and low power is safe, it fits sites with physical properties - mechanical incompetent also can be combined with other methods of exploitation.
