| 为了研究活性炭测氡技术在确定煤层自燃区范围的准确性,采用现场踏勘和红外探测相结合的方法,初步圈定煤层自燃隐蔽高温区和煤自燃氧化区的测氡范围,而后以40 m×10 m网度布置活性炭氡气测点,通过对测点进行平面等值线分析最终圈定火区范围。采用10个钻孔对测氡分析数据进行验证,钻孔数据显示测氡数据分析结果基本准确、可靠。采用活性炭测氡法在宁武县寺耳沟煤矿共确定3处火区的范围,为后期灭火工程提供了准确的基础数据。采用活性炭测氡法在宁武县寺耳沟煤矿成功圈定了煤层自燃区,表明该方法在矿山隐伏火区探测中具有一定的应用前景。 |

| In order to research the accuracy of active carbon radon measurement in coal mine geological environment management, the range of radon measurement in hidden high temperature area and coal spontaneous combustion oxidation area was preliminarily determined by the method of combining infrared detection and field survey, then radon gas measuring points of activated carbon were arranged with a net degree of 40m×10m, and the fire area was obtained by plane contour analysis of the measuring points. Ten boreholes were used to verify the analysis data of radon measurement, and the borehole data showed that the radon measurement data was accurate and effective. The scope of three fire areas by using the active carbon radon measurement in Siergou coal mine, which provided accurate basic data for the fire-fighting project in the mine geological environment control. The application of active carbon radon measurement combined with infrared detection technology in the determination of the scope of Siergou coal mine fire area showed that the method has wide application prospect in the detection of mine geological environment management fire area. |
