Deformation monitoring of open-pit mine restoration and treatment based on InSAR technology
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 moni-toring 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 De-cember 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 moni-toring in the process of surface mine restoration and treatment,and provide effective data support for slope stability and treatment.
