鲍店煤矿103上06综放工作面,因受工作面上方铁路桥搬迁影响,连续缓慢推进,然后封闭1年。3层煤的自然发火期较短,支架顶部、后部及停采线后部采空区的大量松散煤体,蓄热环境好,自燃危险性较大,工作面封闭期间采取综合防治煤层自然发火技术,创造了自燃煤层综放工作面在长时间开放的条件下,无气体和温度异常的防治煤层自然发火佳绩。
Baodian Coal Mine 103 on the 06th fully mechanized caving face, due to the face of the railway bridge above the relocation of the impact of continuous slow progress, and then closed for 1 year. The 3-layer coal has a short spontaneous firing period, a large amount of loose coal at the top, the back and the mined-out area at the back of the support. The thermal storage environment is good and the risk of spontaneous combustion is high. During the closure of the working face, Ignition technology has created a spontaneous combustion coal seam fully mechanized caving face in a long time under the conditions of open, no gas and temperature control of coal spontaneous combustion outstanding results.
