摘要
针对2808工作面回采期间发生的采空区自燃事故,从工作面漏风情况、地质构造、采空区遗煤、推进度等方面分析了事故的原因。根据工作面实际情况,采取了底板岩巷注浆、上下隅角堵漏、采空区充填、局部通风、加快推进度等综合防灭火措施,消除了工作面发火隐患,保证了工作面正常生产。
Aiming at the goal spontaneous combustion accident occurred during the mining of 2808 working face, causes of the accident were analyzed from working face air leakage, geological structure, residual coal in goaf and advancing degree. According to the actual situation, comprehensive fire prevention measures were taken including floor rock roadway grouting, upper and lower corner sealing, filling the goaf, local ventilation and speeding up of advancement. The hidden fire danger in working face was eliminated, and the normal production of working face was ensured.
