Predicción y Análisis de la Contribución de PM10 desde Pilas de Carbón en una Mina a Cielo Abierto

Abstract

The contributions of PM10 to the environment were determined in a mining industrial zone in northern Colombia for activities involved in storing 3.2 Mton of coal. As the main modeling tool the software CALPUFF was used to determine the contribution of PM10 for 10 days modeling during a month period. Ambient concentrations of PM10 in five receivers were measured. Although higher emissions occur during daytime, characterized by high values of wind speed and higher solar radiation, the greater receptivity of PM10 measurements stations occurred during night hours due to the decreasing the mixing height. The modeling results show that the activities involved in carbon storage can provide 14.5% of daily ambient concentrations at receptors located 16.2 km downwind from the source.
