THE RESEARCH OF INFLUENCE THE METAMORPHISM INTENSITYAND PHYSICAL-CHEMICAL PROPERTIES OF COAL ON DUST WETTABILITY
The main direction of industrial safety system on mining enterprises is dust prevention. This problem is particularly acute for mines and coal strip mines. Occupational lung diseases are results of coal dust exposure, which also leads to rapid wear of the equipment and reduces the level of explosion prevention. Workers of coal mines are the most susceptible to this harmful and dangerous effects. The main part of the dust is generated during the destruction of coal bed. Wettability of the resulting coal dust, which depends on the metamorphism intensity, physicalmechanicall and physico-chemical properties of coals are recommended to take into account to improve the effectiveness of dust control. The research results of coal dust wettability, which differs in material composition and petrographic composition are shown.
