基于红外成像技术的煤矿火灾治理

为了快速准确地测出煤层火源位置、范围和燃烧程度,采用红外成像技术对河北煤矿主斜井火区进行了探测,确定火区位置,检验灭火效果。该技术能够准确探测火区表面煤岩体的温度,初步判断火情;对煤岩体表面温度异常区域及其周边设置钻孔,通过观测孔内温度可判断火区范围和煤体燃烧程度,从而确定治理方案。结果表明:在治理过程中利用红外成像仪观测钻孔内的温度变化情况可以更直观地了解灭火效果,说明红外成像技术在治理浅部煤矿火灾中成效显著。

Mine Fire Disaster Control Based on Infrared Imaging Technology

In order to rapidly and correctly search the seam fire resource location,scope and combustion degree,the infrared imaging technology was applied to detect the firing area in the mine main inclined shaft of Hebei Mine. The firing location was determined and the fire extinguishing results were verified. The infrared imaging technology could correctly detect the coal and rock temperature of the firing area surface and could preliminarily judge the firing conditions. As for the coal and rock surface temperature...
