摘要
由于采场矿柱的稳定状态严重影响着地下采场的稳定性,矿柱的保护成为地下采场稳定性研究的重要方向。为研究包裹层对采场矿柱保护的作用,通过Geo Studio2007的SIGMA/W模块对单独矿柱及不同包裹层厚度矿柱在不同上覆岩层压力作用下的位移值、塑性区面积进行了数值模拟计算,为矿山制定安全有效的残矿回采次序和空区处理方案提供科学依据。
Due to the stope pillar stability state seriously affected the stability of the underground stope, protection of the pillar become important direction of the underground stope stability research.For the purpose of studying the wrapping layer on the stope pillar protection, to single pillar and different thickness of pillart, through the SIGMA/W module of Geo Studio2007,numerical simulation calculation of their displacement and plastic zone area is carried out under different overburden pressure,for providing mine scientific guidance for making up safe and effective programs of remnant ore mining sequence and gob disposition.
