矿山岩体内应力重新分布的研究

The research of stress re-distribution after excavating underground

阐述了地应力的重新分布状况,导致围岩发生变形的机理、过程以及对巷道维护所产生的影响。本文通过对弹性岩体中水平圆形硐室围岩应力分布和计算等多种情况的分析,证明了围岩压力的成因、大小与岩体结构及强度关系密切。

This paper elaborates the condition of the ground stress re-distribution,the mechanism and process leading to the deformation of surrounding rocks as well as the impact of roadway maintenance.What＇s more,through the analyses on many kinds of situations such as the stress distribution and stress calculation of the horizontal circular chamber surrounding rock in elastic rock mass,etc,this paper proves that the causes and extent of the pressure of the surrounding rocks are closely related to the structure and strength of the rock.
