Dust transport in mine airways.
Proceedings of the Coal Mine Dust Conference, Morgantown, West Virginia, October 8-10, 1984. Peng, SS, ed., Morgantown, WV: West Virginia University, 1984 Oct; :198-205
The National Academy of Sciences (1) recognized the importance of studying the spatial and temporal characteristics of respirable coal mine dust atmospheres. In this paper, the progress to date of a research project on dust transportation and deposition in mine airways is presented. A mathematical model is proposed for studying the transport of dust. A source representative of dust generation in underground coal mining is defined. The influence and applicability of surface roughness, dispersivities, coagulation and reentrainment to mine dust flow are examined. A convective diffusion model is proposed for the transport and deposition of dust in mine airways. Using the model, the spatial and temporal characteristics can be evaluated in terms of dust concentrations in the mine atmospheres.
