建立固体充填开采下覆岩变形的对称层合板模型，提出模型的定解条件，得到覆岩变形的解析解。采用FLAC建立充填开采覆岩运动的数值计算模型，系统研究充填体密实度、煤层采厚和采深对覆岩变形的影响变化规律。研究表明：采厚和采深对覆岩变形的影响均呈现线性关系；充填体密实度对覆岩变形的影响更为明显。当密实度η<75%时，覆岩变形较大；当密实度η>75%时，覆岩变形量显著减小。研究结果可为固体充填开采理论研究与工艺设计提供参考。

By setting up symmetry laminate model of surrounding rock deformation in solid-stowing mining and presenting definite con-dition, analytical solution of surrounding rock deformation was obtained. Applying FLAC to building up numerical simulation of stowing mining model, the influence of stowing body ' s dense, mining height and mining depth on surrounding rock deformation was re-searched. Results showed that influence of mining height and depth on surrounding rock deformation took on linear relationship. The in-fluence of stowing body's dense on surrounding rock deformation was more obvious. When denseη<75%, deformation was large, and when it was minor than 75%, deformation largely reduced. Research result could provide reference for solid stowing mining theory and technique design.
