摘要
分析综采放顶煤工艺的采空区比分层开采的采空区大2～5倍,推进速度慢,采空区浮煤长期处于自燃带内,防灭火工作难度很大,提出采用三项泡沫防灭火新技术进行防灭火工作,介绍了利用三相泡沫开区灭火的成功经验。
Top-caving coal process is 2 to 5 times larger than layer mining with slow promoting,long-term floating coal gob in the combustion zone,fire prevention and control work is very difficult,three-phase foam for fire extinguishing technology is put forward and successful experiences of three-phase foam fire-fighting is introduced in the open area.
