Gas and Fire Prevention Research and Application of Rujigou Coal Mine 32213_(1) Full-mechanized Mining Face

分析汝箕沟煤矿32213(1)综采工作面现状,阐述了该综采工作面防瓦斯、防灭火的基本方法,论述了合理配置风量、采空区注氮惰化、上下隅角堵漏、底板钻孔、两巷钻孔合理布置有效抽放等综合治理技术以及现场使用情况、使用效果等,为综采工作面防瓦斯、防灭火治理提供新途径。

By analyzing the current status of mechanized mining face of Rujigou Mine 32213（1）,the paper explains the basic methods of gas-fire prevention on the mining face and discusses the rational allocation of air flow,inerting nitrogen injection in mined-out area,upper and lower corner leakage plugging,rational arrangement of effective gas drainage by floor drilling and roadway drilling,as well as the use situation and effect of these techniques on the site.It attempts to proved new ways of gas and fire prevention on full-mechanized mining face.
