| 摘 要： | 为了回收采空区矿柱，以大冶铁矿采空区充填体为例，根据Mohr-Coulomb材料变形模型，建立了采空区应力数值分析模型，模拟了充填前后采空区的应力变化及塑性区的分布情况，通过两者的对比得出充填前后采空区的稳定性结果。研究证明采用充填法对采空区进行处理，不仅改善了采空区应力的作用，还缩小了矿体内的塑性区域，很大程度上提高了采空区的稳定性。

| Abstract: | In order to recover the ore pillars in mined-out area，and taking filling body of mined-out area in Daye Iron Mine as a case，the stress analysis model of the mined-out area is built，based on Mohr-Coulomb material deformation model.The stress variation and the distribution of plastic zone in the mined-out area before and after filling are simulated to obtain the stability of the mined-out area through the contrast.The study shows that filling the mined-out area can not only improve stress action in the mined-out area，but also shorten its plastic zone.To a large extent，backfilling improves the stoping stability of the mined-out area. |
