残煤复采巷道穿越冒落型空区数值模拟的方法

Numerical Simulation of Passing Caving Area of Residual Coal

针对关岭山煤矿在残煤复采时,巷道掘进的过程中如何穿越冒落型空区的问题,利用Flac3D软件进行数值模拟,给出了具体模拟方法,通过分析支护前后巷道围岩的塑形变形、应力应变变化,确定巷道合理支护方案。

In this paper, according to the problem of how to pass through the coring area in the process of roadwayexcavation for residual coal mining, the numerical simulation is carried out by using Flac3D software. The concretesimulation method is given. By analyzing the surrounding rock the deformation of the deformation, stress and strainchanges, to determine the roadway reasonable support program.
