INFLUENCE OF LOW PRESSURE MOISTENING OF COAL LAYERS ON GAS EMISSION IN MINE WORKINGS
In article are presented results of a research of influence of water injection to the coal massif in the low pressure mode. In this regard are considered the structure of coal, modern ideas of its porosity and permeability, filtrational and sorption properties in relation to water and methane. The revealed regularities of influence of moistening on process of gas emission of coal, results of laboratory and mine pilot studies are described.
Keywords: HYDROIMPACT ON UNWORKED COAL, LOW PRESSURE MOISTENING, FILTRATIONAL PROPERTIES, CAPILLARY FORCES, POROSITY AND FISSURING OF ROCK MASS, EXOGENOUS AND ENDOGENOUS CRACKS, EFFICIENCY OF PREVENTIVE PROCESSING.
