Application of Time Series InSAR Method in Mine Deformation Monitoring
Mining subsidence caused by the continuous mining of coal resources will bring different degrees of damage to the surface in-frastructure. Monitoring the deformation of mining area is of great significance to the safety of surface buildings. Based on SBAS-In-SAR technology, the 145 Sentinel-1A image data of a mining area are processed, and the time series deformation monitoring is carried out in the past five years, and the cumulative subsidence amount and annual average subsidence rate of the mine area are obtained. The results show that seven subsidence areas are formed in the mine area, with the maximum cumulative subsidence of 410 mm and the maximum annual subsidence average rate of 83.9 mm/a, and the subsidence tends to deepen and the influence area expands. Fi-nally, the main reason in the mining area is the continuous expansion of construction land. This study shows that the time-series In-SAR technology has a good application in mining deformation monitoring, which can provide scientific basis for the development and u-tilization of mining resources in the future.
