摘要

Dust content in the air is one of the big hazards experienced in hard coal mines. In the result of mining of seams and driving roadheadingscoal and stone dust is generated. Coal dust has explosive properties, and in a certain accumulation and at certain conditions, itcan cause a disaster whereas stone dust has a harmful impact on a human respiratory system and may cause pneumoconiosis. Both kinds ofdust are present in the mine air simultaneously but in different proportions and concentrations. Design solutions and a principle of operationof Bryza-1200 transfer point sprinklers are described in the paper. An application of these sprinklers in coal mines, in differentconfigurations and development of this solution over a period of a recent few years, is presented. Test results are given and an analysis ofdust reduction in the aspect of positioning the components of Bryza-1200 sprinkler, in relation to the conveyor transfer point, is described. Ashape of the transfer point, its speed, the direction of ventilation air flow, dimensions of the working and a position of the conveyor transferpoint in relation to the working axis have an impact on the installation.
