An optoelectronic dust meter, based on the fluctuation method, was proposed as a dust sensor for the dynamic control system of mine ventilation. The scheme of the proposed sensor can significantly reduce the error of continuous measurement of dust concentration to 5%, as well as determine the average size of dust particles in the studied environment, on the basis of which to predict the occurrence of occupational diseases. Dust sensors are installed at a distance of 10-15 meters from sources of dust release (lavas, conveyor lines, etc.), in working faces of a coal mine on incoming and outgoing streams at a height corresponding to the breathing zone of miners.
