摘要
针对河曲矿硬地峁火区煤层自燃等现象,进行了火区分布探测,并制定了相关火区治理方案。硬地峁火区探测采用测氡法地面探测、钻孔探测、红外测温、气样分析、岩样分析等手段,探明了火区的分布范围、燃烧深度和燃烧程度;根据火区探测情况,综合分析火区特点,制定了“火区内地表鱼鳞沟灌黄泥浆-火区边界边坡黄土覆盖压实-地表黄土分层覆盖碾压”的综合灭火技术方案。
In view of the spontaneous combustion of coal seam in hard ground of Hequ coal mine,the distribution of fire area was detected,and the relevant fire control scheme was formulated.The distribution range,combustion depth and combustion degree of the fire area were found out by means of radon detection,borehole detection,infrared temperature measurement,gas sample analysis and rock sample analysis.According to the fire area detection situation and comprehensive analysis of the fire area characteristics,the"surface fish scale ditch irrigation yellow mud in the fire area-loess covering and compaction of the boundary slope of the fire area-layered covering of the surface loess on the surface of the fire area"was formulated"Cover rolling"comprehensive fire-fighting technical scheme.
