摘要
鉴于新峪矿自投产以来10#、11#煤层多次出现发火的情况,5110综放工作面采取了煤层预注阻化液技术进行防灭火。本文阐述了预注阻化液防灭火技术在新峪矿5110综放工作面的成功应用,对阻化剂的选择、注液实施方案进行了详细的阐述,并对防灭火效果进行了深入的分析。
Fire fighting technology of nitrogen injection is one of the most effective technical measures in pre-venting coal seam fire. However, nitrogen is light and loses easily. Regarding the practical situation on 5110fully mechanized coal face of Xin Yu mine coal, this thesis analyzes the combination of nitrogen and foam forfirefighting technology. It elaborates the nitrogen produce equipment, nitrogen injection way, and nitrogen injection technology. Furthermore, it analyzes the fire control results in details.
