Monitoring and Analysis of Dynamic Change of Mining Subsidence Center Based on InSAR
Abstract Taking the Xieqiao coal mine in Yingshang county of Anhui province as an example, we use the InSAR technique to detect the surface deformation results of the mining area from 2007 to 2011. We use the sill model to simulate the deformation of the mining area and analyze the subsidence funnel. The developmental state provides an important reference for regional land subsidence risk assessment. The results of InSAR deformation show that there are many subsidence funnels in the study area, which are generally distributed in the east-west direction. With the passage of time, the subsidence center continues to move and the range of subsidence gradually expands. Combined with remote sensing images, it is found that the formation of the settlement funnel and the collapsed water area is consistent in time, and the spatial distribution is also highly correlated.
