Influence of Mining on Landslide Disturbance Under the Same Inclination of Coal Measure Strata and Landslide

We use similar material simulation experiment method to study coal seam mining of coal-bearing rock series angle of 30 ° under the same inclination of coal measure strata and landslide, and get the maximum caving height of overlying rock is 28.0 m and the maximum crack height of overlying strata is 76.0 m. When the working face advanced a total of 100 meters, the loess landslide was in a state of critical instability. The results of discrete element numerical simulation are in agreement with the experimental results of similar material simulation.
