| 摘 要： | 基于岩移关键层理论，通过试验与理论研究证明了采动覆岩离层主要出现在关键层下，并揭示了离层分布的动态规律．在此基础上论述了覆岩离层注浆减沉钻孔布置的原则，为注浆减沉钻孔设计提供了理论依据．

| Abstract: | Based on the key stratum theory and simulation experiments, it is proved that the bed separation appears mainly below key strata,and the dynamic distribution characteristics of the bed separation have been revealed. From the above results, the layout principle of grouting boreholes for retarding strata subsidence is established. The research results provide a theoretical basis for the layout of grouting boreholes. |
