摘要
煤火自燃不仅严重危害周边生态环境,而且会产生严重的资源浪费和安全隐患。因此,快速准确地识别出煤火的位置与范围至关重要。由此,以阜康市五宫煤矿为研究区,利用多源遥感协同识别的方法确定煤火区域。使用Landsat 8数据与Sentinel-1A数据分别提取高温异常区和持续形变异常区,将高温异常与形变异常区域进行叠加处理,最终获得疑似火区范围。最后利用无人机热红外技术实测煤火范围,对实验结果进行对比分析。结果显示:多源遥感协同识别能有效克服单一识别方式的缺点,提升煤火识别的准确度,为煤田火灾的监测与治理提供科学支持。
Spontaneous combustion of coal not only seriously endangers the surrounding ecological environment but also leads to severe waste of resources and potential safety hazards.Therefore,it is of vital importance to quickly and accurately identify the location and scope of coal fires.In this experiment,taking Wugong coalfield in Fukang City as the research area,the method of multi-source remote sensing collaborative identification was utilized to determine the coal fire area.Landsat 8 data and Sentinel-1A data were used to extract high-temperature abnormal areas and continuously abnormal deformation areas respectively.The high-temperature abnormal areas and deformation abnormal areas were superimposed to obtain the final scope of the suspected fire areas.Finally,the actual scope of the coal fires was measured by using the unmanned aerial vehicle thermal infrared technology,and a comparative analysis of the experimental results was carried out.The results showed that the multi-source remote sensing collaborative identification can effectively overcome the shortcomings of a single identification method,improve the accuracy of coal fire identification,and provide scientific support for the monitoring and treatment of coalfield fires.
