摘要
本论文基于遥感和地理信息系技术,对宁武县余庄乡小煤矿的热红外影像TM11单波段进行密度分割得出热异常区域增强效果图,然后利用TM4、5进行波段运算合成植被覆盖灰度图像,与密度分割后的热红外影像图进行叠加分析,再与DLG的地质岩层数据以及小煤窑分布区域进行叠加分析对宁武煤田余庄乡的小煤矿煤层自燃区进行定位和判断,划定煤层自燃区。
Based on remote sensing technique and geographic information technology,this paper firstly obtained enhancement effect image of thermal anomaly area by density slicing thermal infrared image TM11 single band of Yu Zhuang Township,Ningwu County,Shanxi Province. Then overlay analysing density sliced thermal infrared image and synthesized gray image of vegetation cover by TM4、5 band operation,and then positioning and judging coalfield fires of Yu Zhuang Township,Ningwu Coalfield by overlay analysing DLG geological formations information based on arcgis10. 2 interpretation and small coal mine distribution area,delimiting spontaneous combustion area of coal seam.
