    Dust hazard in drifted headings with continuous miners is discussed in the paper. The amount of dust emission and its harmfulness according to lithological rock properties are taken into consideration. On the basis of measurement results of dust concentration the influence of rock-cutting sort on concentration of respirable fraction is shown. The basic methods for dust controlling in drifted headings are discussed and factors influencing the fault of satisfactory dust collection efficiency are presented. The analyses of the measurement results and dust collection efficiency allowed drawing conclusions about the effectiveness of ventilation - dust collection system.
