Abstract:The surface settlement caused by coal mining has a large impact on the life of nearby residents,and the acquisition of surface settlement data in the mine area is crucial for the production arrangement of the mine.Acquiring a 30-scene image covering the 15302 working face of Pingshu Coal Industry by Sentinel-1 satellite,monitoring the surface subsidence of the mine area using the short-baseline set interferometry tech-nique,obtaining the monitoring data for the past 2 years,and calculating the main parameters of the surface rock movement,which can be calculated that:the amount of settlement in the strike direction of the working face increases with time,the overall average settlement rate of the mine area is more than-30 mm/a,the maxi-mum settlement The average subsidence rate of the mine area is more than-30 mm/a,the maximum subsid-ence rate is-108.87 mm/a,the maximum curvature is-0.1234 mm/m/m,and the rock movement angle is 78.2°.The results show that the surface tilt and curvature in this area are within the permissible values,and the environmental impact of mining in the 15302 working face is relatively small.
