Análisis de la estabilidad de taludes en la mina “María” ubicada en el sector Piuntza, Zamora Chinchipe.

Abstract

This study aimed to analyze the slope stability of the "MARÍA" mine, located in Zamora canton, in order to provide the necessary remediation measures through the evaluation of geotechnical tests and the examination of the same for the continuity of mining work, which emphasizes the extraction of material for the manufacture of ceramics. According to the analysis, two main slopes have been considered and one of them, based on what has been observed, has presented instability, as a consequence of soil sliding. At first, the respective topographic survey of the area has been carried out in detail, proceeding with the taking of the necessary samples prior to carrying out the respective tests to obtain the properties of the soil and rocks of the slope; taking into account that the rocky part does not correspond to a representative percentage, it has been considered a soil slope. The different tests have allowed a physical-mechanical characterization of the different materials present in the slope, by means of the SUCS and AASHTO classifications, in addition to the corresponding triaxial tests for soils and compression for rocks. For the stability analysis, the SLIDE software has been implemented, taking as reference the SPENCER and GLE/Morgenstern-Price methods and the AUTOCAD software has also been included, by means of which the Safety Factors of each entered profile have been obtained, according to the safety factor it was an unstable slope in a state of rupture, so two remediation models have been elaborated by means of Protodyakonov both for the definitive closure and for a progressive closure of slope, thus increasing the safety factor.
