A dust sampler PL-2 is designed to measure respirable fraction without using of pre-selector. On the measurement results does not affect the air velocity. Two optical dust samplers located 100 m and 200 m from the place where the face was mined with a heading machine were used in the excavation ( Fig. 1 ).
