采用三维有限元数值计算方法模拟大倾角煤层采场围岩应力分布,详细介绍了大倾角采场支承压力、底板应力、顶板应力分布的基本特征,据此可进行大倾角采场围岩应力分布的预测,为采场周围有关矿压控制问题提供依据。
Three-dimensional finite element numerical method is used to simulate the stress distribution in the surrounding rock of stope with large inclination. The basic characteristics of bearing stress, floor stress and roof stress distribution in large inclined stope are introduced in detail. Of the forecast for stope around the mine pressure control to provide the basis.
