| description | Mining-industrial processes carried out by anthropic action, bring the generation of impacts to the environment. Between the impacts associated with mining is the involvement of the air quality produced by the release of atmospheric pollutants, being subject to study the behavior of the respirable fraction of particulate matter less than 10 microns (PM10) with respect to meteorological and topographical factors. The analyzed scenarios in the study involved daily and annual exposure times of PM10, in wich modeling with AERMOD View Software was made. The model was carried out in two topographic zones, a complex area, located in the municipality of Socha and a simple area located in the municipality of Sogamoso. It was used meteorological data type satellite, in format .SAM for modeled areas. Three types of emission sources were identified in the areas; considering that the disperse fixed emission sources predominate, followed by the mobile sources and point sources were found in low proportion. PM10 dispersion models made for the zones of simple and complex topography, gave as result that direction and the wind speed is conditioned by the type of zone. It allowed a free flow in the predominant direction in wind rose to the area of simple topography and a turbulent flow in the complex area. It was determined that the sources of emission of PM10 in both cases are local scale; They presented a critical radius of drag and deposition of particles of 200 m approximately. |

Los procesos minero-industriales llevados a cabo por acción antrópica, traen consigo la generación de impactos al medio ambiente, entre los asociados a la minería está la afectación de la calidad del aire producida por la liberación de contaminantes atmosféricos, siendo objeto de estudio el comportamiento de la fracción respirable de material particulado menor a 10 micras (PM10) con respecto a los factores meteorológicos y topográficos. Los escenarios analizados en el estudio involucraron tiempos de exposición diario y anual de PM10, para los cuales se hizo la modelación con el Software AERMOD View. El modelo se corrió para dos zonas topográficas, una zona compleja ubicada en el Municipio de Socha y una zona simple ubicada en el Municipio de Sogamoso. Se empleó información meteorológica horaria de tipo satelital, en formato .SAM para las zonas modeladas. Se identificaron tres tipos de fuentes de emisión en las zonas, teniendo que, predominan las fijas dispersas, seguido de las móviles y en baja proporción las puntuales. Los modelos de dispersión de PM10 realizados para las zonas de topografía simple y compleja, dieron como resultado que la dirección y velocidad del viento está condicionada por la misma. Ésta permitió un flujo libre en la dirección predominante en la rosa de vientos para la zona de topografía simple y un flujo turbulento en la zona compleja. Se determinó que los focos de emisión de PM10 en ambos casos son de escala local, estos presentaron un radio crítico de arrastre y deposición de partículas de 200 m aproximadamente.
