In the study area, land subsidence occurs primarily due to underground mining and subsurface coal fire. The source causes namely different types of underground mining (e.g., bord-and-pillar, longwall mining, depillaring and caving), water logging of the abandoned underground mine workings (or galleries) and subsurface coal fire, are diverse in nature and spatio-temporally haphazard.

of sight (LOS), and surface subsidence obtained using D-InSAR technology neglects the influence of horizontal movement. Surface displacement in the mining area has characteristics of small range and large horizontal displacement. If horizontal displace-ment is ignored, D-InSAR accuracy in monitoring surface subsidence will inevitably be affected.
