充填采矿法和崩落采矿法对地表影响的计算机数值模拟分析

Computer Simulation Analysis of the Impact of Backfill Mining Method and Caving Method on the Surface

基于OpenSees计算平台,运用孔隙介质固液耦合的三维有限单元法,对某矿山西区的采矿行为进行了数值模拟,从不同部位全方位、全面地对比分析、评价了采用两种采矿方法引起的地表沉降问题。

Based on the OpenSees computing platform,this paper conducts the numerical simulation to the mining of the west district of one mine by the three - dimensional finite element method of porous medium coupled solid - liquid model, and contrastively analyses and evaluates the landsubsidence problem caused by the two types of mining methods from different angles.
