介绍了张集煤矿综合采煤工作面在收作及封闭期间采取的防治自然发火所采取的措施,如加强对收作面的预测预报、对采空区注氮、对采空区注浆、对收作工作面降风、严格控制对收作面的抽采、加强对采空区的封闭等,这些措施的实施有效地杜绝了综合采煤工作面进入收作及回棚封闭期间的自然发火隐患,有一定的借鉴意义。 This paper introduces the measures taken to prevent and control spontaneous combustion in the comprehensive coal mining face of Zhangji Coal Mine during the period of closing and closing, such as strengthening the prediction and prediction of the receiving surface, injecting nitrogen into the goaf, grouting into the goaf, The windfall on the receiving face, the strict control of the mining face, and to strengthen the closure of the mined-out area, the implementation of these measures to effectively eliminate the comprehensive coal mining face into the back and back to the closed period of natural Fire hidden dangers, there is some reference.
