中巴资源卫星影像HR数据在煤矿矿区地面塌陷调查中的应用

摘要

We apply, for the first time, the CBERS HR image data whose independent intellectual property rights are owned by China to investigate the surface collapse of coal mine zone through remote sensing technique. A problem which grows serious over time is coal mine zone＇ s surface collapse which features itself by its growing area and both its gradual and sudden change. It is difficult to deter- mine the boundary of the collapse zone and adapt to the development of the problem via conventional station observation. In this paper, we construct a remote sensing image lettering and interpreting system to interpret and delineate the boundary of collapse zones, collect relevant data and support the environmental protection of the region via human computer interaction using Liudaowan - Tieehanggou coal mine zone＇ s CBERS satellite HR image based on known fundamental features of the collapse zone as a case study.%首次应用具有我国自主知识产权的中巴资源卫星影像数据对煤矿矿区采煤地面塌陷进行遥感调查研究。煤矿采空区地面塌陷随着时间日趋严重，面积不断扩大，兼有渐变和突变的特点，用常规方法定点观测难以适应其发展，确定其边界分布非常困难。文章应用中巴资源卫星HR高分辨率影像数据，以六道湾一铁厂沟煤矿矿区为例，通过已知塌陷区的基本特点，建立塌陷区的遥感影像地物解译标志体系，通过人机交互遥感影像解译，圈定地面塌陷的边界并获得塌陷区的有关数据，为该地区环境地质灾害治理提供依据。
