摘要:
井工转露天是一个新的论题,因开采时序的改变,导致边坡体的滑移机制产生了质的变化。应用底面摩擦模型试验和数值模拟方法,针对新的开采时序关系进行了模拟研究,揭示了露天矿延深开采扰动作用下井采区上覆岩体的平衡体系失稳与再活化过程及其演变规律;针对两种开采模式影响域的部分或整体的相互叠加作用特点,分析了自重应力与附加应力的叠加作用属性及开采时序变化对边坡体变形的影响规律,揭示了地下采区对边坡稳定性影响的分区性特点及其影响机制。
Abstract:
Mining converted from underground to open pit is a new thesis, the change of mining sequence caused the slip mechanism of slope qualitative changed. With bottom friction model test and numerical simulation method, this paper made simulating research according to new mining sequence, and reveals the process and the evolution regulation of the overlying rock mass balance system when the mining area of an openpit mine is in the extension mining perturbations. According to mutual superposition characteristics of parts or whole in two mining mode influence domain, the superposition property of gravity stress and additional stress, and the influence law of slope deformation by the change of mining sequence are analyzed. Besides, zoning characteristics and influence mechanism of the slope stability mass deformation by underground mining is revealed.
