采煤沉陷区恢复治理状况遥感调查

Remote sensing investigation of restoration and management situation in coal mine subsidence areas

以山东省某采煤沉陷区为研究区,利用多期光学遥感数据,采用室内研究与野外实地调查相结合的技术方法,旨在研究采煤沉陷区恢复治理状况。研究表明:(1)该研究区内采煤沉陷严重,到2014年采煤沉陷积水区累计面积达13.62 km^2;(2)区内采煤沉陷灾害发展迅速,2006—2014年间,积水面积共增加7.78 km^2,相对于2006年增长了133%;(3)该区沉陷恢复治理状况良好,恢复治理面积达11.70 km^2,恢复治理比例为85.90%;(4)后续的采煤沉陷仍有可能破坏已恢复治理的工程,将已恢复治理的区域转变为需要再次恢复治理的区域;(5)在遥感图像上,恢复治理区域容易与非恢复治理区的地物相混淆,为此,有必要选用多时相遥感数据进行仔细对比。

In this paper,the authors studied restoration and management situation in coal mine subsidence areas using remote sensing images. According to the research objective,the coal mine subsidence area in Shandong Province was chosen as the study area. Multi-stage optical remote sensing images and the technical method which included indoor research and field survey were used. Some conclusions have been reached:(1) Coal mine subsidence in this area was very serious,by 2014,water area had reached 13. 62 km^2;(2) Coal mine subsidence was developed rapidly in this area,from 2006 to 2014,coal mine subsidence water area increased by 7. 78 km^2 totally,and the growth rate was 133%;(3) Restoration and management situation was good in study area,its area reached 11. 70 km^2,and its rate was 85. 90%;(4) Original restoration and management project could be destroyed by flow up coal mine subsidence,and the area needs restoration and management again;(5) In remote sensing images,restoration and management area is easily confused with other features,and hence it is necessary to use multi-temporal remote sensing data for careful comparison.
