Research on Some Theories and Technical Problems Regarding Mining-induced Subsidence

A brief introduction is made in the paper to main research-derived achievements with respects to mining-induced subsidence theories and techniques obtained by Beijing Campus of China University of Mining and Technology for so many years, which include mainly laws of surface movement in coal mines, surface movement laws of mining under condition of giant thick loose strata, overburden movement mechanics and computation of surface movement and deformation in block cut mining, prediction methods of surface movement and deformation in extremely-insufficient mining, study on mining-induced subsidence models based on varied dip angles, prediction methods of surface movement in coal seam mining with a distribution shape of curved surface, mechanics of applying overburden delaminating grouting method to alleviate surface subsidence and evaluation on its effect, and development and research on prediction & analysis system of mining-induced subsidence.
