Abstract: In order to liberate the coal resources lying under buildings，railways and water bodies in maximize，and protect buildings more effectively，combined with the specific engineering examples，the surface subsidence law for strip mining with super high-water material had been studied deeply through FLAC3D numerical simulation and field measurement method，Analysised the surface movement regularity of different filling strip mining scheme, obtained the optimal reasonable exploitation scheme. The results showed that：the buildings were controlled inⅠgrade and the subsidence of surface with the basic roof was coordinated synchronization when using strip mining with backfilling；the simulation and the measured results were basically consistent，the surface subsidence rate reached 95% according the measured conclusion.

Key words: super high-water material, strip mining, basic roof, numerical simulation, field measurement, surface movement regularity
