| 摘 要： | 在露天和井工同期开采下,因边坡体处于井工开采的影响范围内,两种采动效应互相扰动、互相叠加和互相影响,从而构成了复合叠加的作用,边坡体的变形表现为露天和井工两种采动效应叠加的变形机制。以紫金山金铜矿露井联采实例为工程背景,应用Midas GTS软件建立露井联采作用下边坡体三维分析模型,并采用FLAC3D数值模拟软件对三维模型进行数值分析,通过研究各个开采阶段露天边坡体的水平位移、下沉值及应力值,总结露井联采下边坡体的变形机制。

| Abstract: | Conditions of open-pit and underground united mining,The open-pit slope is located in the underground mining affected area,two types of mining effect interaction, overlap and interact with each other,thus constitute a composite superimposed effect,The slope rock mass performance for superimposed deformation mechanism of the open-pit mining and the mining effect.This paper takes an ex-ample of Zijin mountain gold-copper mine open-pit and underground united mining.Midas-GTS software is used to establish the 3D model of the side slope body of Open-pit and underground united mining, and the numerical analysis is carried out by using FLAC3D software.The horizontal displacement,the sinking value and the stress value of the rock mass are studied.The deformation mechanism of the slope under the condition of open-pit and underground united mining is summarized. |
