煤矿井下一氧化碳异常原因及处理对策

Causes of abnormal carbon monoxide in underground coal mines and Countermeasures

煤矿一氧化碳异常是发生煤层自燃的先兆,将会对矿井火灾带来诸多问题,本文基于永川煤矿"7.21"透水涉险事故发生时,南一采区南翼因风量微弱,导致煤层氧化产生一氧化碳进行了原因分析,采取了系列措施进行救援进行探讨,可供类似矿井灾害事故借鉴。

Coal mine carbon monoxide anomaly is the precursor of spontaneous combustion of coal seam,which will bring many problems to mine fire.Based on the“7.21”pervious dangerous accident in Yongchuan Coal Mine,this paper analyzed the causes of carbon monoxide produced by coal seam oxidation in the south wing of Nanyi mining area due to weak air volume,and adopted a series of measures.The rescue can be used for reference for similar mine disasters.
