摘　　要：基于膏体充填开采引起的上覆岩层移动变形结构形态分类,系统分析了充填率如何影响上覆顶板岩层连续性结构的移动变形模式。通过构建膏体充填采场关键顶板岩层的力学模型,深入剖析了顶板组合连续结构岩梁的力学机制、变形特性,以及形成该结构所需的临界充填率与开采条件之间的关系。进一步探讨了膏体充填开采覆岩移动变形空间结构的应力特征及其对控顶区强度的影响,为膏体充填开采的优化设计提供重要的理论依据。Based on the classification of the structural morphology of overlying rock movement and deformation caused by paste filling mining,and systematically analyzes how the filling rate affects the movement and deformation mode of the continuity structure of the overlying roof rock layer.By constructing a mechanical model of the key roof strata in the paste filled mining area,the mechanical mechanism and deformation characteristics of the roof composite continuous structure rock beam were deeply analyzed,as well as the relationship between the critical filling rate required to form the structure and the mining conditions.Further exploration was conducted on the stress characteristics of the spatial structure of overlying rock movement and deformation in paste filling mining,as well as its influence on the strength of the roof control zone,providing important theoretical basis for the optimization design of paste filling mining.
