The Rule of Dust Concentration Distribution at Fully-mechanized Face in Xiaohonggou Coal Mine

Taking the fully-mechanized face in Xiaohonggou Coal Mine as the research object, it decorated reasonable measurement points, and measured the dust concentration of each working procedure in fully-mechanized face with effective measurement methods. It analyzed the measured data, obtained the dust distribution law of every process in fully-mechanized face, and proposed corresponding dust control measures, which provided effective basis for dust control measures of coal mine.
