AB  - In order to conduct in-depth analysis and research on the characteristics of overlying rock failure and fracture development under mining dynamic loads, displacement observation points and stress observation equipment are installed in the model to intuitively analyze the changes in geological displacement and stress distribution characteristics. Layout of displacement points in the strata: The first row is 2cm away from the top of the mined coal seam (55 observation points are arranged in each row, with a distance of 5cm between them, numbered 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 1-7, etc. from the cutting eye to the back). The model is set up in a total of 22 rows from bottom to top.  The dataset contains a total of 729 sets of data.
