采空区CO浓度异常升高原因分析及治理措施

Analysis on Abnormal Rising Cause of CO Concentration in Goaf and Control Measures

针对大柳塔煤矿22101综采工作面采空区内部CO浓度呈数量级异常升高的现象,分析了其CO浓度异常升高的原因,并通过理论分析判断等手段,准确、快速地查明CO源,提出了地面打钻注浆隔离CO源、排矸场覆盖灭火消除CO源、堵漏裂隙、均压通风等治理措施,为矿井安全高效生产提供了技术保证,并积累了经验。

According to the abnormal quantitative rising of the CO content in the goaf of No.22101 fully mechanized coal mining face in Daliuta Mine,the paper analyzed the cause of the CO content abnormal rising.With the theoretical analysis,judgment and other means,the CO sources was accurately and rapidly detected.The measures of the surface drilling and grouting for the insulation of the CO sources,the fire extinguished at the coal reject dumping site for the CO sources control,the crack sealing,the constant ventilation and others were provided and could provide the technical protection and experiences to the mine safety and high efficient production.
