Abstract

The measurement study of the generation, dispersion and retention was carried out at Kiriburu (KIOM) and Meghahatuburu (MIOM), iron ore mines, Odisha state of India. The six days’ average concentrations of particulate matter (PM) with two wide size ranges (PM10-20, and PM0.23-1) were monitored in two iron ore opencast mines. Monitoring was done for three days at the same location at each mines. The increment average concentrations ranged from 15.48-16.74 µg m-3 for PM10-20 and 13.03-29.35 µg m-3 for PM0.23-1 in KIOM and 88.65-92.8 µg m-3 for PM10-20 and 7.89-9.54 µg m-3 for PM0.23-1 in MIOM respectively. Require them to reach the surface are monitored on average 1-2 minute for PM. The retention time of fine PM varies 4-8 minute for KIOM and 1-12 for MIOM, while coarse PM varies 4-5 minute for KIOM and 1-10 for MIOM. The good relationship was obtained between retention time and retention fraction in both KIOM and MIOM. Fine PM shows the higher retention time as compared to coarse PM. The results of this study reveal that relationship between retention time and retention fraction with mining activity and gives the roughly information about time require by PM to reach the surface.
