本文根据国内某矿情况确定了岩体的力学参数与载荷条件,选用三维弹性有限元研究了非对称岩体削弱工程对矿体崩落进程的影响,提出了矿体的破坏机理和判据,以及合理布置岩体削弱工程的一系列原则。
In this paper, the mechanical parameters and loading conditions of the rock mass are determined according to the status of a certain mine in the country. The influence of the asymmetric rock mass weakening process on the caving process of the ore body is studied using three-dimensional elastic finite element method, and the damage mechanism and criteria of the ore body are proposed. A series of principles for the rational arrangement of rock mass weakening works.
