摘要
煤层自然发火防治是综合机械化放顶煤开采过程中的一大技术难题 ,而自然发火期较短、富含瓦斯的特厚煤层则尤为严重。以中国抚顺煤田为研究对象 ,分析了瓦斯抽放与自然发火的一般关系 ,总结了综放开采自然发火的常用防治技术。
Seam spontaneous combustion control is one of the key technical problems in fully mechanized coal caving mining. The seam spontaneous combustion would be often occurred specially in special thick seam with a short period of spontaneous combustion and rich gas. Taking Fushun coal field as an research object, the paper analyzed a general relationship between the gas drainage and spontaneous combustion and summarized conventional control technologies for coal spontaneous combustion occurred in fully mechanized coal mining.
