Abstract
The parameters of the gas environment are considered, determines the factors affecting the course of explosions, determines the critical size of dust for spontaneous combustion. A method for capturing coal dust in order to reduce its accumulation in the working and sanitary protection zones. The studies were carried out using a GANK-4 gas analyzer, a Meteoscope device. The proposed method consists in dry cleaning of the gas-air mixture using a filter element with square cells and an air flow. In the work, the equations of the relationship between the cleaning efficiency and wind speed were obtained. The cleaning efficiency is in the range of 50…79.9%. The maximum value of the degree of purification of exhaust gases is achieved at a wind speed of 6-8 m/s. The proposed method can be applied at enterprises of all sectors of the economy where there are solid fraction emissions.
