水地庄煤矿井下自燃案例探讨

Discussion on coal spontaneous combustion in Shuidizhuang Coal Mine

概述了水地庄煤矿井下火灾的发生、治理过程,分析了火灾发生的原因,就这一案例对如何有效防止煤层自燃进行了探讨,认为,在整合工作快速推进的过程中,各个主体矿井必须对本井田范围内报废或者封闭弃用的煤层巷道整体进行防自燃处理,对这些巷道的永久密闭墙进行检查加固,并实时监测封闭区域一氧化碳及其它火灾指标气体含量,发现有自然发火现象时必须及时通知专业救援队伍,切不可盲目自行打开密闭墙进行处理。

The occurrence and the control of coal spontaneous combustion in Shuidizhuang Coal Mine were described,and the fire causes were analyzed.The discussion on how to effectively prevent the coal spontaneous combustion suggested that the coal spontaneous combustion must be prevented in abandoned or closed coal roadways of each main shaft within the scope of the mine during the whole process of rapid integration.The permanent fire-sealing wall must be often checked and reinforced,and the content of carbon monoxide and other indicative gases in the sealed zones must be real-time monitored by using advanced detection methods.Once the spontaneous combustion occurred,the professional rescue teams should be contacted promptly instead of blindly opening the fire-sealing wall.
