Numerical Analysis of the Impact on the Rise-entry from the Underlying Coal Seam Mined
Using ABAQUS simulated the impact on rise-entry roadway when 9 coal seam was mining. The paper has obtained the stress distribution, the displacement distribution and the tension- compression damage cloud diagram. It showed that the tunnels location was above the range of the baggy fell belt and in the bending sink belt, the ground subsidence was 26cm, which was good consistent with the measured data onsite, and the damage occurred after the underlying coal mined. And the numerical simulative results showed that the general trend of the displacement effected by coal mining, and the research offered some guidance basis for the actual practice.
