Abstract

Modern heavy-duty shearers cut coal with high production of dust particles. The screen tests of coal from Zarechnaya Mine are reported. Methane flow rate is theoretically calculated as function of dispersion phase in coal from Zarechnaya Mine at different particle size distribution of coal. It is found that methane flow rate reaches its maximum in fine coal 0–25 mm in size.
