| 摘 要： | 根据大冶铁矿东露天采场挂帮矿开采的实际情况,建立基于时变力学的数值模型,利用MIDAS/GTS有限元分析软件,模拟并分析了该露天边坡挂帮矿开采的时变规律.模拟结果表明:(1)随着挂帮矿的回采步的推进,回采引起的应力和位移均随之增大,表现出明显的时变规律特征;(2)边坡发生失稳可能性最大的阶段不是在回采的最后一步,而是在...

| Abstract: | According to the actual situation of the hanging-wall ore mining at the east open pit of Daye Iron Mine,a numerical model based on the time-varying mechanics was established.And the time-varying law of the hanging-wall ore mining was simulated and analyzed by using finite element analysis software MIDAS/GTS.The results showed that as the advance of mining steps the slope's stress and displacement incurred by mining increased gradually,presented an obvious time-varying law;the slope instability will occur mo... |
