基于星载雷达数据的舒兰市典型矿区地面形变监测研究

Research on Ground Deformation Monitoring of Typical Mining Areas in Shulan City Based on Satellite Radar Data

煤炭资源是推动我国经济发展的主要能源之一,但随着国民经济发展水平的大幅提升,煤炭资源的过度开采也对人们的生活和环境产生了一系列不良影响。本次研究基于Sentinel-1A遥感影像,利用PS-InSAR技术对吉林省舒兰市西南部的东富二矿进行地面变形监测,得到矿区地面的形变信息,确定了沉陷区域的范围和不同位置的沉降值。研究结果表明,PS-InSAR技术比传统方法更为直观地展现了矿区的动态变化,能够精确地测出地表的沉降量、抬升量及沉降速率,可为生态环境的恢复治理提供依据。

Coal resources are one of the main energy sources to promote my country's economic development.However,with the substantial increase in the level of national economic development,the excessive exploitation of coal resources has also produced a series of adverse effects on people's lives and the environment.This study is based on Sentinel-1A remote sensing images,using PS-InSAR technology to monitor the ground deformation of the Dongfu No.2 Mine in the southwestern part of Shulan City,Jilin Province,and obtain ground deformation information of the mining area to determine the scope of the subsidence area and the subsidence value at different locations.The research results show that the PS-InSAR technology more intuitively shows the dynamic changes of the mining area than traditional methods,can accurately measure the surface subsidence,uplift and subsidence rate,and can provide a basis for the restoration and management of the ecological environment.
