摘　　要：综采工作面液压支架工作阻力对于监测工作面矿压显现规律有着十分重要的影响。对神东矿区补连塔煤矿12煤四盘区在不同开采条件下5.0 m液压支架工作阻力数据进行理论分析和实际观测,总结出5.0 m综采工作面在初采、正常回采以及末采期间的矿压显现规律。The working resistance of hydraulic support in fully mechanized working face has a very important influence on the monitoring of the underground pressure of the working face. In this paper, through the theoretical analysis and actual observation of the work resistance data of 5.0 m hydraulic support under different mining conditions in No.4 panel of 12^# coal in Bulianta Coal Mine of Shendong Mining Area, the paper summarizes the strata behaviors of initial mining, normal mining and end mining in the fully mechanized working face of 5.0 m.

关 键 词：工作阻力 初采 末采 矿压显现 液压支架
