Battelle esti- mated the totalfugitive dust emissionsfrom surfaceminingof coal in Western states to be 0.1 lb/ton of overburden removed and indicated that overburden removal was the larg- est emission source at these mines.10 Considering the common ratios of overburden removed to coal mined (5:1 to 20:1), Battelle's factor appears to .be an order of magnitude higher than Hittman's value.

Fugitive emissionsfrom metal and slag tapping, casting, crushing and screening are the largest source of Mn-bearing PM at ground level. Enhancements in control of PM and reduction in occupational exposure can be achieved by trapping and recyclingfugitive dust.Get Price
Dustgeneration from haul roads is a problem for most surface coal-miningoperations and especially those in semi-arid and arid areas. For these mines, which rarely have optimally designed and maintained roads, classifying different levels of dustiness, quantifying the impact on safety and assigning priorities within the constraints of limited capital and manpower are problematic.Get Price

Jul 23, 2018· In this paper, a co-polymer based suppressant was used, aiming to find a good method to cope with thefugitive dust emissions. The three concentration rates of co-polymer baseddustsuppressants were prepared: 1%, 3%, and 5% by weight. The soil was sampled in Sedona, Arizona, USA, and was mixed with co-polymer baseddustsuppressants.Get Price
Jan 01, 2018· With very significant CO 2, CH 4, and N 2 Oemissionsfrom differentminingactivities asfugitive emissions, coalminingis a major contributor to the buildup of GHGs in the atmosphere. These gases allow solar energy to reach the earth's surface but delay that energy's escape into space, and thus effectively trapping heat in the lower atmosphere.Get Price
