以邢东矿1123采空区自然发火为例,分析了大采深、高地压采空区自然发火的原因,提出了治理大采深、高地压火区的均压灭火、水封灭火等措施,给出了防水墙体的参数计算方法,为大采深、高地压采空区自然发火的预防提供了可借鉴的经验。
Taking the spontaneous combustion of 1123 goafs in Xingdong Coal Mine as an example, the reasons of spontaneous combustion in goaf with large mining depth and high pressure were analyzed. Some measures were put forward, such as pressure equalization fire extinguishing and water seal fire extinguishing in large mining area and high pressure area The method of calculating the parameters of waterproofing wall is given, which provides a reference for the prevention of spontaneous combustion in large mining and high pressure gob area.
