Biological action of coal dust formed during excavation of seams after physicochemical treatment

Journal Article:

Abstract

Destruction of the self-cleansing function of lungs by dust is important in the development of pneumoconiosis. It is expedient to study the influence of chemical substances, injected into coal seams to prevent methane bursts and reduce dust formation, on the physiologic mechanisms for the protection of the lungs from dust (macrophageal reaction of lungs, function of mucociliary transport). An investigation using 15, 24 and 50% solutions of binder KM/SUB/2 modified by polyvinyl alcohol, and 3% hydrochloric acid solution was conducted on 200 white rats. Reaction of rats treated with solutions of binder in different concentrations proved that accumulation of dust in lungs and lymph nodes was directly related to the strength of the solution. Three percent hydrochloric acid solution diminished dust accumulation in paratracheal lymph nodes and content of lipids and collagen in the lungs. Inhalation of dust treated with a 50% solution of binder KM/SUB/2 increases the deposit of dust in the lungs and increases fiber production. Therefore, solutions of more than 24% binder should not be used to treat coal. Solutions of 15% and 24% do not significantly affect the process of dust accumulation in the lungs. A 3% solution of hydrochloric acid reduces the dust-forming capacity of  More>>
