Systematic Fire Prevention Design Analysis of 3-5#Coal Seam in Yongdingzhuang Coal Industry
Not only the coal mine with high gas and easy spontaneous combustion has fire hazards,but also the coal mine with low gas and easy spontaneous combustion also has high gas accumulation areas.Therefore,it is necessary to design a reasonable comprehensive fire prevention system to ensure the safe production of the mine.This paper has Yongdingzhuang coal industry 3-5#coal seam as the background,a systematic analysis of the potential fire hazard sources in mine production and pointed out the prevention and control countermeasures,according to the geological conditions of the mine and mining technology and inert gas injection anti-fire method,spraying retarder anti-fire method and yellow mud grouting anti-fire adaptation and advantages and disadvantages design with daily nitrogen injection as the main method,spraying retarder as auxiliary means,yellow mud grouting system as standby measures of comprehensive fire prevention system,which provides a reference for the design of mine fire prevention system.
