| 摘 要： | 为了深入研究充填开采煤柱、矸石之间的相互作用关系，对碎矸体与巷采煤柱形成的组合结构在上覆岩层荷载作用下的力学机理进行了研究，形成了充填碎矸体对煤柱提供侧向约束力时的煤柱稳定性理论。结合晓楠煤矿工程实例，对不同采留比、不同碎矸体压缩率等充填效果进行了研究，研究结果对充填开采工程实践具有指导意义。

| Abstract: | In order to research the interaction between coal pillar and gangue in filling mining, the mechanical mechanism of the composite structure of coal pillar and gangue is researched under the overlying stratars load, then the theory is formed that the filling gangue provides lateral restraint force for coal piUar＇s stability. Combined with Xiaonan coal mine project, the filling effect under the different mining and reservation ratio and gangue compression ratio is researched, and the result has guiding significance for the filling mining. |
