西石门铁矿南采区盘区开采规划的三维有限元分析

3-dimension Finite Element Analysis of Panel Mining Plan to the South Mining District in Xishimen Mine

文中抓住西石门铁矿南采区盘区开采线前方底板采准巷道的稳定性这一关键问题,按开采年度模拟盘区开采规划,获得了开采线前方底板中的应力状态,然后对底板采准巷道的稳定性进行了预测,并给出了整个开采区域上的破坏分布。

This paper presents 3 -D FEM analysis of the panel mining planning of the southern mining district in Xishimen Iron Mine. In order to solve a key problem of the development gallery stability in the foot wall in the front of mining line, the stress conditions in the foot in the front of mining line is obtained based on annual mining planning of the simulated panel, then the stability of the development gallerys in the foot wall is predicted, and failure distribution on the overall mining district is given.
