Resumen
El presente proyecto de tesis contiene el análisis del uso de estériles de
minería para la producción de hormigón y shotcrete en obras subterráneas, para el caso
de estudio Chuquicamata subterráneo. Para justificar el uso de estériles se revisaron los
antecedentes del proyecto como sus bases técnicas para determinar las exigencias de
este, luego se realizó la validación del material de acuerdo con la NCh 163 2013 producto
de los ensayos realizados a los áridos de sus características físicas y químicas, como
también hormigones de prueba utilizando dicho material. Adicional a lo descrito
anteriormente se utilizó la demanda anual establecida en el proyecto para generar una
demanda aleatoria con un código realizado en MATLAB y con las restricciones del
proyecto, para obtener la máxima demanda de hormigón y áridos por hora, para luego
proponer un modelo de planta que cumpla esas características respectivamente.
Finalmente se realizaron una serie de propuestas con respecto a las bases técnicas,
plantas y control de calidad con el fin de proponer mejoras que permitan la utilización del
material estéril para hormigones utilizados en el proyecto.
This thesis project contains the analysis of the use of mining waste to produce concrete and shotcrete in underground works, for the Chuquicamata underground case study. To justify the use of sterile, the antecedents of the project were reviewed as its technical bases to determine its requirements, then the material was validated inaccordance with NCh 163 2013 as a result of the tests carried out on the aggregates of their physical characteristics and chemicals, as well as test concretes using such material. In addition to what was previously described, the annual demand established in the project was used to generate a random demand with a code made in MATLAB and with the project's restrictions, to obtain the maximum demand for concrete and aggregates per hour, and then propose a model of plant that meets these characteristics respectively. Finally, a series of proposals were made regarding the technical bases, plants and quality control in order to propose improvements that allow the use of sterile material for concrete used in the project.
