摘要
依据矿井防灭火理论基础,结合公司下属各矿井实际情况,对综放工作面在支架回撤期间采取的综合防灭火措施进行系统论述及比较。以工作面回撤的时间和步骤为节点,详细阐述了回采后期、铺网上绳期间、扩回撤通道期间、回撤期间采取综合防灭火方法的适用性,针对矿井实际情况做出适宜的防灭火方法,并应用于综放工作面支架回撤期间,有效防止了采空区自然发火,为工作面支架顺利回撤提供了保障。
According to the theoretical basis of mine fire prevention and fighting,combined with the actual situation of the subordinate mines of the company,the comprehensive fire prevention and fighting measures taken in the support withdrawal period of the fully-mechanized top coal caving face are systematically discussed and compared.Taking the time and steps of the withdrawal of the working face as the node,the applicability of the comprehensive fire prevention and extinguishing methods adopted in the late mining period,during the laying of wire rope,during the expansion of the withdrawal channel,and during the withdrawal period is described in detail.The appropriate fire prevention and extinguishing methods are made according to the actual situation of the mine,and applied to the withdrawal period of the support in the fully-mechanized caving working face,effectively preventing the spontaneous fire in the goaf,and providing a guarantee for the smooth withdrawal of the support in the working face.
