复杂火区条件下煤火圈划和火源位置探测方法及应用

应用同位素测氡法探测技术对老二井火区进行了精确探测，并结合数值插值技术对野外测氡数据进行相应处理，得成了火区氡测值等值线和火区高温火源位置分布等值线，进而区分了该火区东西测场内的温度异常区和燃烧区。分析结果表明，西区温度异常区总面积约255477m2，东区温度异常总面积约70370m2，为该矿区灭火方案的设计提供了科学依据，也可为国内同类问题的解决提供参考。

The combustion zone probing & fire location detecting in complex coal mine fire zone

The method of underground coal fire investigation was presented in this paper by using isotopic radon measurement. Combining with interpolation method in data processing, measurement data were transformed to radon isoline graph and fire locating isoline graph, and by this, the temperature anomaly area and combustion area were distinguished. Finally, as the consequences of analysis, underground anomaly heating zones were detected in both of the west and east areas of experimented fire zone, with areas of 25 5477 m2 and 7 0370 m2 respectively. It can provid scientific basis for the coal mine to design coal fire control plan, and also provide references to domestic similar researches.
