摘要
利用FLAC3D软件,模拟马头山地下采矿活动诱发西风井岩体移动变形、主应力变化等开采效应的时空演变过程,研究西风井的地压效应,并进行岩体稳定性评价。
By using FLAC^3D software, this paper simulates the mining effect＇ s space-time evolution process of displacement, deformation and principal stress changes of rock mass around west ventilation shaft induced by mining activities in Matoushan orebody, so as to study the pressure effect on west ventilation shaft, and evaluate the stability of the rock mass.
