Monitoring of coal mining subsidence and inversion of mining process in the Shenmu and Fugu based on InSAR technology
In order to effectively monitor the continuous land subsidence phenomenon in northern Shaanxi Province caused by long-term underground mining,this paper relies on a practical project,uses SBAS-InSAR technology to process Sentinel-1 data covering Shenmu and Fugu from January 8,2020 to November 27,2020,and obtains the scope and depth of ground subsidence caused by underground mining during the observation period.The D-InSAR technique is used to invert a mining face in this area.At the same time,the SB AS-InSAR monitoring results are compared with the level data,and the difference is between 1.8 and 8.1 mm,which met the monitoring accuracy requirements,and proved the reliability of SBAS-InSAR technology in monitoring the surface subsidence of mining areas.By comparing the D-InSAR inversion results with the data provided by the mine,it is found that the two are consistent,which proves the feasibility of D-InSAR technology in the inversion of coal mining process.
