Numerical Analysis of Mining-Induced Overburden Stress Change Rule

Abstract:

Based on overburden of S2S9 working face fully-mechanized mining of certain coal mine, this paper uses the finite element ADINA software to analyze the vertical stress and shear stress of overburden under the condition of coal mining, especially the vertical stress decreasing and increasing zones, concentrated stress change and to discuss the distribution scope, peak value and spatial relation with the working face of Tre-suptorping stress. The study on the mine safe and efficient mining of other face has certain significance.
