摘　　要：超静定充填液压支架主要是用来解决煤炭开采中的"三下"压煤问题,具体来说是将矸石和粉煤灰作充填材料,在煤炭开采中,充填采空区,防止地表下沉。介绍了一种新型充填液压支架,一方面在支架的架型结构选择上采用超静定结构,支架承载能力更强;重新设计了充填结构,使得充填效果更好。Hyper-static filling hydraulic support is mainly used to solve the problem of ＂Three under＂ pressure coal in coal mining. Specifically, the Mined-out area is filled with gangue and pulverized coal, in order to prevent the earth＇s surface from sinking. A new kind of filling hydraulic support is introduced in this paper. On the one hand, hyper-static structure is applied in this support, which makes it carries bigger capacity; on the other hand, the filling structure is redesigned, which has a better filling effect.
