摘要
利用大型有限元分析软件ANSYS对工作面进行应力模拟,得出沿工作面法线方向应力分布规律,并进一步分析应力变化对煤层透气性系数的影响,为瓦斯治理及煤和瓦斯突出预测提供技术支持。
The stress distribution rule along the normal of working surface can be acquired through stress stim- ulation on the working surface by ANSYS, and further analyze goes on the impact that can be done on the coal seam permeability by the changes of stress. By which technical support on the gas control as well as the fore- cast of coal and outbursts of gas can be achieved.
