Reduction of dustiness in the mine atmosphere of the working face of dead-end workings through the use of reasonable and effective parameters of ventilation and dust collection systems when they work together. The work uses analytical methods to study aerology and dust dynamics processes during the combined operation of ventilation and dust collection systems. It has been established that when ventilation and dust collection systems work together, phenomena occur that can significantly reduce the efficiency of these systems and ultimately lead to emergency situations, as well as increase the risk of occupational diseases of fibrogenic action. Based on the research, matrices of mutual influence of ventilation and dust collection systems have been developed, which allow determining the range of efficiency of the joint operation of dust collection and ventilation systems in dead-end mine workings. The factors of mutual influence of aerology and dust dynamics processes that determine the state of the mine atmosphere and the level of safety in the near-face space of a dead-end mine have been scientifically substantiated; it has been shown that this influence is determined by the parameters of ventilation flows, which depend on the performance of ventilation and dust collection equipment. The practical significance of the results obtained lies in the use of the developed matrices of the influence of the joint operation of ventilation and dust collection systems to improve sanitary and hygienic conditions and increase the level of safety in the working face of mine workings when they are carried out by mechanised means.
