新安矿回采对巷道影响的数据模拟研究

Numerical Simulation of Mining Influence on Roadways in Xin'an Mine

双鸭山矿业集团新安煤矿共有三个可采的的单一煤层,随着采深的增加,工作面回采的采动影响对周围巷道的影响将日益加强,基于此以8号煤层为例,进行了数据模拟,分析了采动对巷道围岩应力分布和位移特征,为矿山巷道的支护提供了科学依据。

There are three minable single coal seams in Xin＆#39;an Mine, Shuangyashan Mining Group. With the mining deepening, the mining influence on the surrounding roadways increases. Taking an example of No.8 coal seam, numerical simulation was conducted to study the stress distribution and displacement of surrounding rocks caused by mining, which could provide a scientific basis for the roadway support.
