摘要
矿山岩体工程开挖将引起周围岩体的移动和变形 ,如果某区域的岩体受到不同开挖工程的共同作用 ,那么岩体内应力状态将是各个影响因素综合作用的结果。本文将应用底面摩擦模型试验方法 ,主要研究和探讨在先期进行地下开采 ,然后进行露天开采条件下 ,边坡岩体的动态滑移机制及其变形规律 ,以便为此类矿山后续开采设计及边坡岩体动态分析提供科学依据。
Displacement and deformation of surrounding rockmass of mining works can be caused by excavation in mine. If rock mass is effected by different excavations jointly, the stress of rockmass is influenced by all kinds of factors. In this paper an experimental method of friction model of bottom surface is used to study the mechanism for dynamic slide and deformation regularities of rockmass under firstly underground mining and then open pitting, so as to provide a scientific basis for design of continous mining and for dynamic analysis of slope rockmass.
