不同断面大小的煤巷围岩离层变形数值模拟研究

Numerical Simulation on Separation Deformation of Surrounding Rocks in Coal Alley with Different Cross-sections

以王庄煤矿6210工作面回风巷为对象,经在相邻岩层中建立接触面单元,进行岩层离层的数值模拟研究,得出巷道围岩的离层与巷道高度的必然联系的结论。

Taking return airway of 6210 working face as the study object, interface elements were established in the adjacent strata to simulate the separation and concluded the necessary correlation between the separation of the surrounding rocks and the height of the roadway.
