Description
Summary:The coal mining industry in Russia is developing rapidly. In this regard, the increase in emissions of coal dust into the environment leads to a serious threat to the safety and health of employees of enterprises and to deterioration of environmental situation. One of the methods in the fight against coal dust pollution is the use of dust-settling reagents. Studies for developing the composition of dust-binding mixtures, characterized by a minimum adhesion (wettability) of coal dust particles, have been conducted. The kinetics of the process of wetting dust with various dust-settling reagents has been studied. It is established that the use of solutions of sodium oleate with the addition of linseed oil is a good dust-settling reagent of natural origin. The adhesion time significantly reduces by adding linseed oil. The greatest efficiency of dust deposition was noted when interacting with a solution of sodium oleate with the addition of linseed oil with a concentration of 4 g/l, when the moisture content of dust was 60 %. The results obtained will contribute to improve the environmental and sanitary conditions of settlements located near operating coal mining enterprises and reduce the incidence of specific diseases among employees of the enterprise.
