Diseño de un sistema de explotación en la concesión minera Ramos Huayco, código 600575, cantón Saraguro-Loja.

Abstract

This tesis aimed to design an exploitation system in Ramos Huayco mining concession, through the assisted software for the exploitation of construction materials. The methodology applied for the design of the exploitation system, considered aspects taken in the field and in the laboratory. In the field, two predominant materials were identified (mineral of interest and sterile), which are distinguished by the coloring and resistance of each one. The topographic survey of the study area was carried out through 3d photogrammetry and by using the following softwares: arcGIS, QGIS, AutoCAD and Civil 3D. The topography, estimate possible resources and other necessary parameters for the design of the exploitation system were analyzed. Likewise, the geomechanical characterization of the rock was carried out using the Bienawski classification. At the Espoch laboratories, different properties were determined per each of the mine materials. The analysis of the exploitation of quarries by descending benches was considered by means of a preparation stage and three exploitation stages. Subsequently, the economic viability of the exploitation system was determined based on three scenarios with different daily productions. Finally, being the first study carried out, the application of the descending benches exploitation system was not feasible due to the high content of sterile material and the low commercial demand, at least until finding a use for the sterile material, until then the artisanal extraction of construction material inside the mine is maintained.
