Based on surface movement observation data analysis in the Yushuwan coalmine, studied surface movement deformation pat-tern and characteristics resulted from mining of thick coal seams under extra-thick sandy soil layer condition. The study has revealed impacts from special factors of extra-thick sandy soil layer, thin bedrock and large shear height on surface subsidence patterns, and sur-face movement and deformation characteristics under those conditions. The result has important practical significance in safe rational mining, protective pillar setting, environment management and protection in later stage development of Yulin coalmines.
