Abstract: The article is devoted to the problem of intensive dust release of coal during its transportation in a mine, which, if dust suppression measures are not followed, increases the explosion hazard of mine workings. In the event of a gas dynamic phenomenon that led to an accident followed by an explosion of a dust and gas mixture, deposits of explosive coal dust after passing through the shock wave front are blown up in the mine atmosphere of the mine workings and contribute to the development of the explosion force as the flame front advances. Within the framework of the "Clean Mine" concept, the task has been set to conduct a study of the dust release and explosion hazard of coal dust, and it is also planned to develop technical means aimed at significantly reducing the volume of coal dust deposits through the network of main mine workings by performing a major "purification" of the air of the mine atmosphere in the immediate vicinity of sources of increased dust release (places of destruction of mining mass and transportation overloads from belt to belt) in the course of the movement of the air jet. The article analyzes the actual data of dust emission during the transportation of coal through the mining workings of various mines in Kuzbass. An analysis of the actual dust emission data indicated the formation of a large amount of coal dust deposits in the mine workings, which, due to the physico-chemical properties of the extracted coal and the lack of effectiveness of dust suppression measures and the technical means used, may pose a threat to the safe conduct of mining operations. It is proposed to develop a technical means adapted to mine conditions to control dust release in places where coal is reloaded from a conveyor belt to a belt, taking into account the experience of processing plants in using dust collecting devices.
