摘要
针对C13煤层,尤其是中底区采煤工作面均不同程度的存在自燃发火安全隐患,甚至造成工作面因自燃发火而封闭;提出了利用矿井注氮系统、灌浆系统,采用打钻注氮、灌浆的方法,消除自燃发火安全隐患,保障安全生产。
Mining working face, especially in the middle and end zone, exist spontaneous combustion safety problems in different degrees, and even cause working face closed due to spontaneous combustion. Taking C13 seam for example, to eliminate safety hazards and ensure safety in production are putting for- ward by using nitrogen-injection system and filling system and adopting the method of drilling nitrogen-injection and filling.
