【摘要】：首山礦開采易燃突出煤層,工作面風(fēng)量大,采空區(qū)浮煤易自燃,為了防止氮氣注入采空區(qū)后漏失嚴(yán)重,采用向采空區(qū)注重氮防火技術(shù),取得了好的防火效果。介紹了實驗室對重氮配比、流速和降氧效果的試驗方法和結(jié)果,介紹了首山煤礦重氮防滅火系統(tǒng)的組成和工作面注重氮的方法、參數(shù),分析了采空區(qū)注重氮后的降氧、降溫和抑制浮煤自然發(fā)火的效果。
[Abstract]:Shoushan Mine mining flammable outburst coal seam, the working face air volume is large, goaf floating coal is easy to spontaneous combustion, in order to prevent serious leakage after nitrogen injection into goaf, attention to nitrogen fire prevention technology in goaf has been adopted, and good fire prevention effect has been obtained. This paper introduces the test methods and results of diazo ratio, flow rate and oxygen reduction effect in laboratory, introduces the composition of diazo fire prevention and extinguishing system in Shoushan Coal Mine and the method and parameters of paying attention to nitrogen in working face, and analyzes the effect of reducing oxygen, cooling down and inhibiting spontaneous combustion of floating coal after paying attention to nitrogen in goaf.
