Monitoring and Analysis of Surface Deformation in Mining Area Based on InSAR and GRACE

Remote Sensing, 2018
To determine the relationship between underground mining, groundwater storage change, and surface deformation, we first used two sets of ENVISAT data and one set of Sentinel-1A data to obtain surface deformation in eastern Xuzhou coalfield based on the ...

Ground Surface Deformation in the Hanging Wall of the Jinshandian Underground Iron Mine in China

Frontiers in Earth Science, 2022
When sublevel caving is used in metal mines, the stress state in the rock mass that initially existed around the mined-out area will be destroyed. This will lead to the rock strata deforming and moving and also, potentially, to large-scale collapse and ...
