山东省济宁市煤矿矿集区地面沉陷现状遥感调查

Investigation of current surface subsidence situation using remote semsing images,in Jining coal mine concentration area,Shandong Province

山东省济宁地区煤矿资源丰富,但煤矿资源的开采利用造成了严重的地面沉陷。本文旨在调查济宁市煤矿矿集区地面沉陷的现状。在调查过程中主要采用最新获取的GeoEye-1高空间分辨率遥感影像,并结合历史资料分析研究区内地面沉陷造成的危害。通过遥感调查发现研究区内有地面沉陷积水坑47个,积水面积达2828hm2。地面沉陷已造成了20个村庄的搬迁,破坏土地约2667hm2,严重影响了当地人民的生活。本文使用遥感手段开展地面沉陷调查工作,充分反映了研究区地面沉陷灾害的实际情况,也充分体现了遥感技术快速、宏观的特点。

The resources of coal mine is abundant in Jining area,Shandong Province,but there are serious surface subsidence caused by the development and utilization of coal mines.This article aims to investigate the status of surface subsidence in coal mining concentration area of Jining.The latest high spatial resolution GeoEye-1 remote sensing image was mainly used during this investigation,and the hazards which had been caused by this surface subsidence in the study area were analyzed combined with historical data.47 surface subsidence plashes were found though remote sensing investigation in the research area,and the area of plashes reaches 2828ha.20 villages had been relocated,more than 2667 ha farm land had been destroyed by the surface subsidence.The surface subsidence caused serious implications to the lives of local people.This article uses remote sensing to carry out surface subsidence investigation,and the survey results fully reflect the actual situation of surface subsidence hazards.Also,the rapid,macroscopic features of remote sensing technology were fully displayed in this research.
