山西乡宁井坝湾煤矿井下自燃案例分析

Case study on coal spontaneous combustion in Jingbawan Coal Mine in Shanxi

概述了乡宁井坝湾煤矿井下火灾的发生、治理过程,分析了火灾发生的原因,就这一案例如何有效防止煤层自燃进行了探讨。指出在整合工作快速推进过程中,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进行防自燃处理,并实时监测封闭区域一氧化碳及其他火灾指标气体含量。

This paper presents the details of a fire that occurred and the process of resolution in Jingbawan Coal Mine in Xiangning. The causative factors of the fire has been analyzed. Ways to effectively prevent spontaneous combustion of coal seams have been discussed based on this case study. In the rapidly integration of work, the closed coal roadways must implement sponta- neous combustion prevention measures. CO and other gas fire indicators in the sealed areas should be real-time monitored.
