高位巷道瓦斯抽采对煤自燃三带分布影响研究
|
摘要
为研究高位巷道瓦斯抽采对煤自燃三带分布的影响,运用理论分析结合现场实测,在考虑遗煤瓦斯涌出及高位巷道抽采影响因素的基础上,基于氧气体积分数建立了高位巷道抽采下采空区三带的划分方法,结合现场实测得出:高位巷抽采致使进风侧自燃带加宽,回风侧自燃带范围缩小的结论。
In order to study the effect of gas extraction by upper roadway on the three zones distribution of coal spontaneous combustion,by using theoretical analysis and field test,and considering the influence of residual coal gas emission and high-level roadway extraction,the three-zone division method of goaf under high-level roadway extraction was established based on oxygen volume fraction. Field measurement shows that the gas extraction in high-level roadway widens the spontaneous combustion zone on the intake side and narrows the spontaneous combustion zone on the return side.
