针对王庄煤矿在村庄下压煤开采方面面临的技术难题，本文依据王庄煤矿的地质条件，提出了非连续刀柱式矸石充填开采的技术方案，通过采用UDEC数值计算的手段，从关键层位垂直位移、关键层位水平位移、模型中央监测点垂直位移和下沉速度、采场主要围岩体稳定性等角度，对提出的三类方案进行了定量和定性对比分析，得出了非连续刀柱的最优技术参数，将为生产实践提供有力参考。

According to difficult problems of Wangzhuang mine in the aspect of under village mining , based of its geological condition , the technical schemes of discontinuous rib pillar waste filling are put forward.By adopting on UDEC numerical simulation , the quantitative and qualitative analysis is made to propose three technical schemes in the aspect of vertical and horizontal displacement of key strata , vertical displacement and velocity of monitoring point in the middle of model , stability of surrounding rock. The optimization technical parameters are obtained on discontinuous rib pillar , and it will supply reference to production practice.
