Caracterización geomecánica y mineralógica de materiales de relaves mineros en el cantón Zaruma, para su utilización en medidas de cierre de galerías mineras

Abstract

The Mining District "Zaruma - Portovelo" has a high mining activity that has historically been the basis of its economy. The works of exploitation go back to the colonial period approximately to the year of 1550 until the colonial time. However, lack of planning, non-technified work (artisanal exploitation), indiscriminate exploitation and the search of economic growth by the population have generated serious problems. These which directly affected the city of Zaruma (Subsidense in the Educational Unit "The Immaculate, Fe y Alegría"). The Zaruma town was declared a World Patrimony Site by UNESCO in 1998, which is why it is of great cultural and historical value for our country and making its preservation a priority. The objective of this work is to perform an analysis of tailings materials generated by mining exploitation in that zone, to use them as raw material for "mortars" to carry out works to stabilize and close mining galleries in this town. The aim of this study is to propose solutions for the subsidence problems that currently affects Zaruma town.
