Study on Mechanics Model and Stress Evolution Law of Filling Stope
The paper sets up mechanical model according to the characteristics of paste filling stope and determines the basic model units which are overlying strata,filling body,support and floor.The paper also establishes the mechanical parameters for controlling movement and deformation of overlying strata and sets up the relationship of all mechanical parameters.Based on this,the paper studies the stress evolution law under the condition of different filling ratio and filling step distance with the method of numerical simulation.
