【摘要】：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。
[Abstract]:Due to the mining of ancient kiln in Datong mining area, the private mining of small coal kiln has formed many dark fire areas burning in the shallow layer of the surface. According to the characteristics of these fire areas, Landsat TM/ETM temperature inversion, UAV and ground infrared thermal imager are used to monitor the coal fire area of Majiliang Mine. The thermal field distribution information of coal fire area in 2000, 2002, 2006, 2007 and 2009 is extracted by Landsat TM/ETM image, the change process is analyzed, and the approximate range of coal fire area is delineated. Using UAV optical camera to take the high resolution image of fire area, combined with the texture, line feature and gray value of ground fissures in coal fire area, the knowledge model is established, and the structural cracks in coal fire combustion area are extracted, which provides the basis for detecting and controlling underground coal fire. The temperature field information of key areas of coal fire combustion is collected by infrared thermal imager, and the hot spot trend and the depth of ignition point are analyzed, which provides the basis for determining the combustion point of coal fire area.
