Classification of dust reduction systems in the mining works

The development of the coal industry is closely related to the increase in the productivity of mining equipment. To increase the speed of sinking mine workings in the coal mines of Russia, modern tunneling combines are used. When they are used, the flow of dust into the mine atmosphere of dead-end mine workings increases. This significantly increases the risk of accidents associated with coal dust explosions. The article proposes a classification of measures to reduce the dust content of the mine atmosphere of mine workings during their sinking. The number of cases of occupational diseases of dust etiology is also growing. To reduce the danger in coal mines, a whole range of various measures described in this article and aimed at reducing dust is used. At the same time, there is currently no unified approach to the selection of an event. The paper provides an analysis of the applied anti-dust systems, including irrigation, dust deposition and dust extraction. The classification makes it possible to systematize the available data in the field of dedusting the mine atmosphere of mine workings during their sinking. The classification is based on an approach similar to that of coal mine exchartation schemes. In the development of this classification, studies of dust suction systems built into tunneling combines were carried out. The article presents all possible schemes for the proposed classification.

Keywords: mining work, dust, safety, ventilation, scrubber, irrigation, classification, dustiness.
