应用遥感技术调查研究煤层自燃灾害

本文主要论述利用遥感技术对我国北方煤层已经熄灭的自燃火区及正在燃烧的活火区进行圈定的方法。死人区范围是以烧变岩反射光谱特征为依据,利用黑白及彩红外航空摄影图像进行解译圈定;大面积活火区则是以其热辐射特征为依据,利用热红外扫描图像解译圈定分布范围,小面积活火区则利用地面红外测温技术圈定分布范围,并取得了明显效果。

THE APPLICATION OF REMOTE SENSING TECHNOLOGY IN THE HAZARD OF COAL SPONTANEOUS COMBUSTION

In this paper, the methods are discussed to define tile death-fire and fire region caused by the coal spontaneous combustion in the North of China. According to the theory of reflectance spectra of burnt rocks, the death fire area is defined by means of the interpretation of the aerial photographs. On the basis of the law of heat radiation, The border of the fire region is defired by means of the infrared scanning images, and the small regions by the means of the infrared measuring technology on the ground. And obvious economic profits have been acquired.
