Annotation. The paper considers the principle of constructing a control system of energy-efficient mine ventilation by using new dust detectors that can function in difficult operating conditions. One of such automatic dust meter sensors is described, which contains two sources of radiation in the measuring and reference channels operating at wavelengths in the region of maximum and minimum dust absorption, the radiation which are transmitted sequentially using prisms and mirrors directed through the measuring and reference channels into a single light stream and then to the input of a broadband photodetector. To give the system the possibility to function in difficult operating condi-tions, the sensor comprises a blower device that contains a protective windows and a heating viewing windows that maintains the temperature of the measuring channel within specified limits. The use of such sensors makes it possible to quickly make decisions about the redistribution of air in mine con-trolled by the mine ventilation control system.
