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. The entire overlying strata model is equipped with 10 rows of survey lines, with 24 survey points arranged on each line. The distance between horizontally adjacent survey points is 10 cm, and the distance between vertically adjacent survey lines and the coal seam roof is 0 cm, 8 cm, 16 cm, 26 cm, 31 cm, 42 cm, 47 cm, 55 cm, 75 cm, and 90 cm, respectively. Data source: Measurement points in indoor similar simulation test models were used to obtain displacement values at different heights from the coal seam roof.
The dataset contains a total of 240 sets of data.

Indoor data analysis.
The entire overlying strata model is equipped with 10 rows of survey lines, with 24 survey points arranged on each line. The distance between horizontally adjacent survey points is 10 cm, and the distance between vertically adjacent survey lines and the coal seam roof is 0 cm, 8 cm, 16 cm, 26 cm, 31 cm, 42 cm, 47 cm, 55 cm, 75 cm, and 90 cm, respectively. Data source: Displacement of observation points in indoor similar experimental models, obtaining relative displacement values of different observation points.
The data quality is good.
