大同矿区由于古窑开采、小煤窑私挖滥采形成了众多在地表浅层燃烧的暗火火区。针对这些火区特点，利用 Landsat TM/ETM 温度反演、无人机和地面红外热像仪等集成分析技术监测马脊梁矿煤火区。利用 Landsat TM/ETM影像提取2000年、2002年、2006年、2007年和2009年5个时期的煤火区热场分布信息，分析其变化过程，圈定煤火区的大致范围；利用无人机搭载光学相机拍摄火区的高分辨率影像，结合煤火区地裂缝的纹理、线特征和灰度值等信息，建立知识模型，提取煤火燃烧区的构造裂缝，为探测、治理地下煤火提供了依据；利用红外热像仪采集煤火燃烧重点区域的温度场信息，进行热点趋势和着火点深度分析，为确定煤火区燃烧点提供依据。

Numerous coal fires burn underneath the Datong coalfield because of indiscriminate mining. Landsat TM/ETM, unmanned aerial vehicle (UAV), and infrared thermal imager were employed to monitor underground coal fires in the Majiliang mining area. The thermal field distributions of this area in 2000, 2002, 2006, 2007, and 2009 were obtained using Landsat TM/ETM. The changes in the distribution were then analyzed to approximate the locations of the coal fires. Through UAV imagery employed at a very high resolution (0.2 m), the texture information, linear features, and brightness of the ground fissures in the coal fire area were determined. All these data were combined to build a knowledge model of determining fissures and were used to support underground coal fire detection. An infrared thermal imager was used to map the thermal field distribution of areas where coal fire is serious. Results were analyzed to identify the hot spot trend and the depth of the burning point.
