| Abstract (English): |
Landslides caused by changes in land use, or by anthropic activities such as open-pit mining, constitute one of the most important socioeconomic risk factors in countries with developing economies. This article presents an approach to the relationships between mining activity and the development of landslides in a pilot area located in Soacha, Cundinamarca. Through data mining analysis and the use of Geographic Information Systems (GIS), an evaluation of the possible relationships of these factors was carried out, including socioeconomic aspects. From an inventory of open-pit mining sites, the geomechanical characterization of soil and rock units, and the characterization of environmental and social variables, data were obtained to define variables whose relationships were determined by algorithms programmed in the GIS. The results show that there is an indirect relationship between open-pit mining activity and landslides development over the last four decades in the studied zone. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): |
Los fenómenos de remoción en masa causados por cambios en el uso del suelo, o por actividades antrópicas como la minería, constituyen uno de los factores de riesgo socioeconómico más importantes en países con economías en desarrollo. Este artículo presenta un enfoque para la evaluación de las relaciones entre la actividad minera y el desarrollo de deslizamientos en un área piloto ubicada en Soacha, Cundinamarca. Mediante análisis de minería de datos y el uso de Sistemas de Información Geográfica (SIG), se llevó a cabo la evaluación de las posibles relaciones de estos factores, incluyendo aspectos socioeconómicos. A partir de un inventario de canteras, la caracterización geomecánica de unidades aflorantes, y la caracterización de variables ambientales y sociales, se obtuvieron datos que definieron variables cuyas relaciones se determinaron mediante algoritmos en el SIG. Los resultados muestran que existe una relación indirecta entre la actividad minera y el desarrollo de deslizamientos en las últimas cuatro décadas en el área estudiada. [ABSTRACT FROM AUTHOR] |
