摘要
通过对阳城沁水矿区煤层顶板岩石相互摩擦引燃引爆瓦斯模拟实验 ,得出“岩石在冒落过程中相互撞击摩擦产生火花 ,可能引起瓦斯与空气混合物着火 ,是造成采空区瓦斯爆炸 (燃烧 )事故引爆源”的结论。
Through methane simulation experiment on ignition and blasting due to seam roof rock friction in Qinshui Coal Mining District of Yangcheng, it is shown that sparks will be generated through friction while caving ,causing gas and water mixture to fire, it is big hidden sources which cause methane blasting accident in goaf.
