Experimental Studies of Dispersion and Transport of Respirable Dusts in Mine Atmospheres.
For Reference Only At Bureau Libraries :162 pages
This report describes a study on dust dispersion around the face area in order to control dust concentrations. The effects of varying line brattice locations and air quantity changes were studied using methane and Arizona road dust to simulate respirable coal dust. Measurements were taken at 25 grid points for each brattice distance and air quantity combination both in the absence and presence of mine face machines. Test results are included, and concentration data are presented in a series of tables and figures.
