Uso de água para abatimento de particulados em suspensão

Abstract

Used data from the Carajas iron ore mine, N4E mine collected in the period of 05 to 31 July. It is located in the city of Paraupebas - PA, in the town of Carajás, 860 km from the capital, Belem, and 789 km from the ferry terminal of Ponta da Madeira. (-6° 3' 17.237"S, -50° 10' 22.667"W) east of the state of Para Data were collected along a ramp slope of 15% for a potentially longer period of dust generator. The purpose of this study was to examine the system of abatement of particulate matter used in the mine area and propose an alternative adjustment of a sprinkler system of agriculture. The values obtained in measurements over this period were the basis for calculating the number of trucks needed to promote barrels a more efficient reduction of airborne dust. During the most intense traffic of trucks off the road, the need to spray water access was two times higher than when the trucks were just as often. It was found that the periods of greatest need were the sprinkling of 16 to 18 hours, since the heat absorbed by the earth during the afternoon was being released in the early evening.
