Analysis on Discontinuous Rib Pillar Waste Filling under Village by Numerical Simulation
WEI Xiao-dong
Abstract：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.
