摘要
在资源整合前,小窑与大矿争资源,开采原有煤柱,导致采空区长期供风供氧。采空区一旦发生自燃火灾,大量有毒有害气体将通过漏风通道进入大矿,严重威胁矿井安全和职工人身安全。某矿曾受小窑火灾影响发生采空区次生火灾及CO气体泄出事件,但都得到及时治理并总结了相应措施。由于成功从工作面火区撤下86个支架,减少损失1548万元,同时保证了全矿运煤系统集中皮带的正常运行。
Small kiln compete with the big mining resources,mining original pillar,causing gob oxygen for long -term wind before Integration of resources.The spontaneous combusted in gob will make a large number of toxic and harmful gases through air leakage channels into large mine,and could serious threaten to mine safety and worker safety.Gob secondary event of fire and CO gas escaped happened in Datong Coal Mine Group affected by small kiln mine fire. However,it had been timely treatment and summarizes the corresponding measures.Due to the success from the 8913 fire area face removed 86 brackets,it saved 15.48 million Yuan,and guaranteeing that the centralized system of coal mine belt running.
