dc.description.abstract | En la actualidad los proyectos extractivos afrontan grandes retos de sostenibilidad en los territorios donde se llevan a cabo, tradicionalmente las variables ambientales y sociales no han sido tenidas en cuenta en los procesos de optimización y secuenciamiento de planes de minado, alejándose de resultados holísticos y de bajo riesgo. Los esfuerzos por disminuir la incertidumbre geológica, económica y operativa han sido considerables en los últimos años, sin embargo, son pocas las investigaciones que dan respuesta a los problemas de incertidumbre ambiental y social que pueden presentar los proyectos. En esta investigación se plantea la internalización de los costos asociados con el cierre de mina, costos ambientales y costos de solución de conflictos, calculados con base en ecuaciones sugeridas por varios autores en el estado del arte. Se aborda el caso base de una mina de carbón a cielo abierto ubicada en Colombia con condiciones iniciales previamente establecidas y con costos asociados, calculados después del proceso de optimización. Posteriormente se genera un nuevo caso en el que estos costos son cargados en la valorización económica del mineral castigando su poder calorífico. Al finalizar se realiza un análisis de sensibilidad con las proyecciones futuras del precio del carbón. Los resultados obtenidos indican que, internalizando estos costos, es posible disminuir el riesgo de la inversión y hay una mejoría en el rendimiento operativo, social y ambiental del caso de estudio. Resultados que podrían beneficiar a la compañía, al Estado y a las comunidades. (Texto tomado de la fuente) | spa |
dc.description.abstract | At present, extractive projects face larges sustainability challenges in the territories where they are carried out, traditionally environmental and social variables have not been taken into account in the processes of optimization and sequencing of mining plans, moving away from holistic results and low risk. Efforts to reduce geological, economic and operational uncertainty have been considerable in recent years, however, few investigations provide an answer to the problems of environmental and social uncertainty that projects may present. This research proposes the internalization of the costs associated with the closure of the mine, environmental costs and costs of conflict resolution, calculated based on equations suggested by various authors in the state of the art. The base case of an open pit coal mine located in Colombia with previously established initial conditions and associated costs, calculated after the optimization process, is addressed. Subsequently, a new case is generated in which these costs are charged to the economic valuation of the mineral, punishing its calorific value. At the end, a sensitivity analysis is carried out with the future projections of the price of coal. The results obtained indicate that, by internalizing these costs, it is possible to reduce the investment risk and there is an improvement in the operational, social and environmental performance of the case study. Results that could benefit the company, the State and the communities. | eng |
