摘要
以可见光黑白航片(1:3.5万)为主要信息源,对陕西神府煤田新民烧变区(1300km^2)进行了1:5万航空遥感地质调查,圈定了该区烧变岩分布范围及煤层自燃边界。首先划分了烧变岩的宏观类型,选取已知区,研究烧变岩及煤层自燃边界线的影像特征,建立初步解译标志,最后在全区范围内调查煤层自燃边界线。最终确定的界线经钻孔验证,精度达到要求。
Black/white aerial photographs with visible light (1: 35,000)are used as main information source to fufil aeroremote sensing survey on scale of 1: 50,000 in Xingming district in this investigation. Distribution of burnt rock ignition boundary of coal seams in Xingming district covered an aera of 1, 300 km^2 have been identified. The first task is to divide marco—lithotype of burnt rocks. The second task is to establish preliminary interpreting indices by means of studying image features of burnt rock and ignition boundary, which is carried out in a known area selected in the light of existed data. The third task is to complete the remote sensing investigation for burnt coal boundary all over the district.
