采用弹塑性理论,综合考虑了国内某矿山矿体的赋存条件,建立了采场稳定性分析的三维有限元模型,研究了充填采矿法不同结构参数时采场的稳定性以及围岩应力和位移随矿房、矿柱尺寸以及采场控顶高度的变化情况.研究结果表明：采场最大压应力和最大拉应力随矿柱宽度增大而减少,随矿房宽度增大而增大;该矿山合理的采场结构尺寸为矿柱宽8 m,矿房宽10 m,控顶高度8～12 m.
摘要(英文)：
Using elastic-plasticity theory and considering the occurrence condition of a certain mine, we built a 3-D numerical model of stope stability, studied the stability of the stope with different structural parameters in back-filling mining method and analyzed stress and displacement of stope surrounding rock in accordance with structural parameters of stope such as pillar size, room size and stope lamination height. The results show that 1) the max compressive stress and max tensile stress in the stope decrease with the increase of pillar width and increases with the increase of room width, and ...
