Factibilidad técnica económica minera de la explotación de feldespato en la concesión minera Rosario II código 100217.1

Abstract

This research proposes: to determine the mining technical and economic facility of the exploitation of Feldspar in Rosario II mining concession, located in Yunganza parish, canton General Leonidas Plaza Gutierrez – Limón Indanza, province of Morona Santiago; through a technical analysis of geological, lithological and geotechnical parameters of a reservoir mantle shapes of nonmetallic mineral; execution by computer geographic systems used topographic base issued by the Military Geographic Institute. (IGM) called Limón topographic sheet at a scale of 1:50.000 it was drawn all the study maps. In the first part, corroboration of a geological – geotechnical study was presented by geological and geomechanical description. The main part was performed using the profiling or cutting method to calculate proven, probable reserves and overload of study area, with data obtained the volumes exploration and production of feldspar mine were planned. Additionally knowing the geometric, geomechanical and operating conditions the system of exploitation arises by “Descending Banks” and the final design of mine exploitation. It is concluded by economic analysis by TMAR, NPV, and IRR to determine the technical economic and mining feasibility of nonmetallic mineral (Feldspar). Keywords: Rosario mining concession, exploitation of feldspar, geomechanical rock, proven reserves, descending bank.
