Análisis geomecánico e identificación de estructuras de mineralización de la concesión Asonambile zona 2 (Ex – Condominio Norte), sector Nambija, parroquia San Carlos de las Minas.

Abstract

The present research work was executed in the company Asonambile S.A, in the Nambija neighborhood of the San Carlos de las Minas parish, province of Zamora Chinchipe, Ecuador. The objective of the research was to perform a geomechanical characterization of the rock mass, identifying the main discontinuities present, as well as identifying mineralized structures. It will be presented mainly, the perspective on how to work in an underground mine, taking into account the stability of the same and the indications of how to look for the mineralization, together with the determination of the type of exploitation used. Geomechanical surveys were carried out by the classifications, Rock Mass Rating (RMR) of Bieniawski and the Barton Q index, together with a rock sampling for mineralogy analysis; besides the use of digital software for the geomechanical study of rocks (DIPS v5, auto CAD, Unwedge, Recmin), obtaining a modeling of the characterization and identification process. After the aforementioned analysis, it was obtained that in the study area we have rock masses from a very good quality, to poor quality in both RMR and Q index.
