A theoretical method and its numerical simulation to calculate roof stress of coal floor

摘要：

Using the method of limitless broad of the banding and the elasticity complex function we give an analytic solution fitting to the roof stress of coal floor, and it is easily to achieve the roof stress distribution according to formulations and numerical integration. In addition, a practical model is calculated by the theoretic formulations and the finite element method (ANSYS program) in the paper, and the results calculated by the two methods are also compared with each other.
