Analysis of Surface Movement and Deformation Monitoring in Underground Mines Based on Differential Interferometric Radar Measurements
Aiming at the risk of deformation and damage of surface buildings(structures)that may be induced by the underground mining,this paper carries out long-term monitoring of the surface of a certain underground mining mine by D-InSAR method,and the results of the study show that:the areas with significant reduction of the surface are caused by the compaction of the site leveling and backfill bulk,and the characteristics of the surface subsidence in the rest of the area are not significantly different from those outside the mine,and the impact of the underground mining on surface subsidence is very small.The field survey shows that there is no obvious cracking and deformation phenomenon of the current surface buildings(structures),which verifies the analysis results of the D-InSAR monitoring data.
