摘要:
利用FLAC3D软件对大冶铁矿东露天高陡边坡、露天转地下-72m水平29号采矿巷道建立模型,模拟了无边坡影响、高边坡影响2种情况下,采矿巷道的位移变化以及塑性区分布情况,并根据29号采矿巷道收敛监测结果,验证巷道数值模拟结果。通过采用不同围岩分级方法对采矿巷道进行评价,比较研究得出东露天采场采矿巷道围岩稳定性情况。
Abstract:
It used the FLAC3D software to establish the valid model for east open pit high and steep slope and No.29 mining tunnel on the -72 m level of transition from open pit to underground, and simulated the displacement change and distribution of plastic zone of the mining tunnel with no slope influence and high slope influence. It verified the numerical simulation results according to the convergence monitoring results of No.29 mining tunnel. It adopted various rock mass classification methods to appraise the mining, compared and analyzed the stability condition of mining tunnel by different methods.
