摘要
煤炭等矿产资源大规模的开采,满足了我国经济建设需求的同时,也导致了地面塌陷、采空区沉降等一系列灾害,严重制约着矿区环境、社会经济的可持续发展。合成孔径雷达干涉测量技术以其全天时、全天候、高精度和大面积覆盖监测的优势将成为监测矿区灾害的首选技术。以新疆某露天矿区为研究对象,选取2018年2—12月的升降轨哨兵数据,基于SARscape软件,采用SBAS-InSAR技术进行处理,得到该煤矿的时间序列形变图及形变速率图,并对形变速率进行了二维分解,获取到东西向和垂直向的形变速率,矿坑内坡体的东西向形变速率在-140~40 mm/a,垂直向形变速率在-196~20 mm/a。研究表明,InSAR技术可以有效应用于露天矿恢复治理过程中的形变监测,为边坡稳定及治理工作提供有效的数据支撑。
Large-scale mining of coal and other mineral resources has not only met the needs of China′s economic construction,but also caused a series of disasters such as ground subsidence and goaf settlement,which severely restricted the mining area environment and the sustainable development of society and economy.Synthetic aperture radar interferometry technology will be the first choice for monitoring disasters in mining areas due to its advantages of all-day,all-weather,high-precision and large-area coverage monitoring.A open-pit coal mining area in Xinjiang was taken as the research object,the ascending and descending orbit sentinel data from February to December 2018 were selected and processed by SBAS-InSAR technology based on SARscape software,the time series deformation map and deformation rate map of the coal mine were obtained,and the deformation rate was decomposed in two dimensions to obtain the east-west and vertical deformation rates,and the east-west deformation rate of the slope in the mine was between-140~40 mm/a,the vertical deformation rate was between-196~20 mm/a.The study shows that InSAR technology can be effectively applied to deformation monitoring in the process of surface mine restoration and treatment,and provide effective data support for slope stability and treatment.
