补连塔煤矿12煤采空区高温区域治理实践

Governance Practice for High Temperature Area at №.12 Coal Gob in Bulianta Coal Mine

补连塔煤矿22305工作面在开采过程中曾受12煤采空区自燃影响而被迫关闭,为保证三盘区剩余工作面的安全开采,必须对12煤采空区高温区域治理效果进行评价。介绍了12煤采空区自燃情况和治理过程,分析了自2012年10月-2013年9月高温区域的煤炭自燃标志性气体的变化趋势,进行了高温区域的温度测试,得出12煤采空区高温区域处于窒息状态,不会对三盘区将要开采的其他工作面构成威胁,并给出了原高温区域的后续管控措施。

Due to the influence of spontaneous combustion in 12 coal gob ,22305 working face in Bulianta Coal Mine had to be closed. The governance effect of high temperature area in 12 coal gob must be evaluated to ensure the safe mining of surplus working faces in Sanpan area. The spontaneous combustion situation and governance process of 12 coal gob was introduced, the variation trend of sponta- neous combustion indicator gas in the high temperature area was analyzed from October 2012 to September 2013, and the temperature was also tested. The evaluation conclusion showed that the high temperature area in 12 coal gob was in a state of suffocation, and it would not pose a threat to the surplus working faces in in Sanpan area. Finally the subsequem control measures of the original high temperature area were given.
