Mining damage identification based on SBAS-InSAR technology
In order to efficiently and reliably identify mining subsidence damage of the mining area in Dongpo Coal Mine,Shanxi Province,synthetic aperture radar interferometry(InSAR)technology was used to monitor and analyze the mining-induced surface deformation.At the same time,the probability integral model was used to predict the surface movement and deformation.Then,the mining boundary was determined using the boundary angle,and field investigation was carried out to determine whether the mining-induced surface deformation would damage to a nearby village.According to the analysis of InSAR deformation monitoring results and predicted surface movement deformation in the mining area from January 2007 to April 2019,the village was always outside the mining damage boundary determined by the boundary angle.And no signs of mining damage to the buildings was found in the field investigation.
