复采工作面火灾事故案例分析与综合防治

Fire Accident Case Analysis and Integrated Control in Second Mining Fully Mechanized Caving Face

以小煤矿严重破坏区复采综放工作面3起火灾事故为案例,分析火灾原因,提出了复采工作面穿越小煤矿破坏区特殊支护、消火道防灭火等防治小煤矿自然发火技术,结合工作面破坏区灌浆超前防治、局部均压、注氮等防灭火措施,有效地消除了火灾事故,确保工作面顺利回采。

From three cases of fire accidents in caving mining faces of small coal mines severely damaged area,Analyzing the cause of the fire,the paper proposed the technology of special support,the fire prevention of firefighting road in small coal mine destruction zone,combining with the advance prevention by grouting,partial pressure equalizing and nitrogen injection,which effectively eliminated the fire accident and ensured the face smooth recovery.
