摘要:
为了研究红外热成像法和测氡法联合探测技术在探测上覆煤层小窑区自然发火火源位置的应用效果。采用理论分析和现场实测相结合的方法,首先,分析了2种方法在实践应用中的优缺点; 其次,研究了自燃煤层释放氡在裂隙岩体中的运移和扩散规律,同时建立了自燃火源传热模型,分析了红外热成像法的探测机理; 最后,以公乌素煤业有限责任公司1604工作面上覆9#煤层小窑火区为现场探测对象,综合采用RAD7专业电子测氡仪和T335型红外成像仪对火源位置及其范围进行了探测。研究表明:在测氡法中,裂隙岩体中任意位置处的氡气浓度均可由岩体表面氡气浓度通过理论计算得出,但氡的扩散系数及衰减常数等参数受地形变化影响差异很大,不易确定; 而红外热成像探测深度一般为10 m左右,火源位置越深,探测难度越大; 现场氡气浓度测试及红外热成像方法探测结果显示在1604工作面上部地表存在2个氡异常区域,且两区域的位置与红外热成像探测结果相符。总体而言,红外热成像法和测氡法联合使用可以互补缺陷,可确保火源位置的进一步精确定位,对火区的治理方案提供科学依据。
Abstract:
To research the application effects of united technologies combined with infrared themral imaging method(ITIM)and radon measurement method(RMM)in detecting the fire source of spontaneous combustion existed in the small kiln fire area of ovelying coal seam.Combining the methods of theoretical analysis and field measurement,firstly,analyse the merits and drawbacks of these two methods,and then study the migration and difusion rules of releasing radon through the fractured rock mass,and mathematic model for simulating the heat diffusion of spontaneous combusion was established,then the detection mechanism of ITIM was analysed.In the end,using the industrial instruments to detect the location and scope of fire source.Research shows that:The radon concentration at any position in the fractured rock mass can be calculated by the value at the surface,but the diffusion coefficient and attenuation coefficient were hard to determinated due to the topography variation; And the detection depth of ITIM is generally about 10m,the deeper of the fire source,the harder to detect; through the field data of RMM and ITIM,two areas have obviously radon concentration and temperature were detected,the results of the two methods were same.Overall,the ITIM and RMM can be combined used to ensure the further accurate positioning,providing a scientific basic to guide the conflagration treatment.
