长期高强度的煤炭开采和地下水抽采,导致淮北市地表发生大面积沉降,破坏了耕地以及生态环境,因此对地表沉降监测显得尤为重要.本文通过短基线集合成孔径雷达干涉测量(SBAS-InSAR)方法获取了2020年1月5日到2020年12月30日的淮北市地表年形变速率,并且使用水准数据对监测结果进行了精度验证.结果表明:淮北市沉降存在不均匀现象,年形变速率为-55～42 mm,淮北市地表沉降由地下煤炭资源开采和地下水抽采引起,主要地表沉降由采煤引起.研究结果可为地质灾害预防提供数据参考.
Monitoring and analysis of surface subsidence in Huaibei based on SBAS-InSAR technology
Long-term high-intensity coal mining and groundwater extraction have caused large-scale surface subsidence in Huaibei City,destroying farmland and ecological environments. Therefore,surface subsidence monitoring is important. This paper used the small baseline subset-interferometric synthetic aperture radar (SBAS-InSAR) method to obtain the annual surface deformation rate of Huaibei City from January 5,2020 to December 30,2020 and employed leveling data to verify the accuracy of the monitoring results. The results show that there is uneven subsidence in Huaibei City,with the annual deformation rate ranging from-55 mm to 42 mm. The surface subsidence in Huaibei City is caused by underground coal resource mining and groundwater extraction. The main surface subsidence is caused by coal mining. The research results can provide data reference for geological disaster prevention.
