The aim of this work is to show a methodological proposal for the analysis of soil intervention values in mine tailings in order to determine the intervention requirements in the commune of Andacollo in northern Chile. The purpose of this analysis is to guide the intervention policies of both private and public organizations. The evaluation method is based on the Dutch legislation. The usability of the proposed methods depends on the available geochemical data from soil samples; in particular, we tackle the case when information regarding clay percentage in the soil is not available. We use the concepts of a threshold factor and an adjusted threshold factor to calculate a weighted intervention ranking. In order to illustrate the utility of this methodological proposal, a case study is carried out with the prescribed approach. In particular, this work presents an analysis of the elements of environmental significance related to the mining activity (Hg, Cd, Pb, As, Cu, Ni, Zn, Cr) in the commune of Andacollo, Coquimbo Region, Chile. The analyzed samples are used to determine where the intervention of tailing deposits is necessary and where a solution to these environmental liabilities is required as soon as possible. Out of the 81 samples evaluated, it was found that 18 require a potential intervention, and of these samples, seven of them are associated with abandoned tailings that, in some cases, are located close to the town center itself, one sample is associated with active tailings and the other 10 with inactive tailings.
Resumen: La minería de procesos es un campo que utiliza elementos de la minería de datos y el modelamiento de procesos para realizar tareas de descubrimiento, evaluación de conformidad y mejora de procesos. El objetivo de este artículo es mostrar la aplicación y utilidad de la minería de procesos en la ingeniería de software. Se presenta una serie de casos de estudio que ilustran aplicaciones sobre el proceso y el producto. Además, se muestran los desafíos a los que se enfrenta la minería de procesos en la ingeniería de software. El principal resultado de esta investigación corresponde a que el uso de minería de procesos facilita la evaluación y auditoría de procesos de software. Se propone como trabajo futuro el desarrollo de una metodología para la aplicación de la minería de procesos en la ingeniería de software. Palabras-clave: minería de procesos; desarrollo de software; evaluación de procesos; mejora de procesos.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
