巷道煤柱高温点分布规律及五区定位法的研究

Study on distribution law of high temperature points in mine gateway coal pillar and five zone positioning method

在煤矿巷道发生自燃时,准确确定火源位置是救灾关键,为了深入研究火源定位机理,根据高温在煤柱中热传导规律,总结了巷道自燃后温度分布的可能5种情形,采用流体动力学数值模拟软件Fluent研究巷道自燃后温度场和温度曲线图的分布,提出了煤柱自燃"五区定位法",为当前煤矿现场救灾时确定火源点、实施打钻注浆灭火提供技术指导。

During the spontaneous combustion occurred in a coal mine, to correctly position the fire location was the key of the disaster rescue. To deep study the fire resource positioning mechanism, the paper, based on the thermal conducted law of high temperature in the coal pillar, summarized the five kinds of the temperature distributions when the spontaneous combustion occurred in the mine gateway. The hydrodynamic numerical simulation software—Fluent was applied to study the distribution of the temperature fiel...
