摘　　要：简要介绍了多年来中国矿业大学北京校区在开采沉陷理论与技术方面的主要研究成果：矿区地表移动规律；巨厚松散层条件下开采地表移动规律；块段开采条件下覆岩移动机理及地表移动变形计算；极不充分开采地表移动变形预计方法；基于倾角变化的开采沉陷模型研究；曲面分布形式煤层开采地表移动预计方法；覆岩离层注浆减缓地表沉降机理及减沉效果评价方法。开采沉陷预测分析系统的开发研究等。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.
