Research on Hydrogen Sulfide Gas Technology in 2-501 Fully Mechanized Coal Face of Lumbo Coal Industry
With the development of mining technology and the increase of mining depth,high sulfur coal mining is imperative,and high sulfur coal containing high concentration of hydrogen sulfide gas is likely to increase significantly,this paper is based on the background of advanced treatment of hydrogen sulfide gas in Longbo 2-501 fully mechanized coal face,and analyzes the gas treatment effect by pressure injection of 15%alkaline mixture and high-pressure spraying of alkaline mixture in the rich area of hydrogen sulfide in coal body.The comprehensive treatment technology of hydrogen sulfide in 2-501 fully mechanized coal face is determined.The quantity of hydrogen sulfide gas emission from coal body is obviously reduced during actual mining,and the treatment effect is good.
