%X In order to deeply analyze and study the characteristics of overburden failure and fracture development under mining dynamic load, displacement observation points and stress observation equipment are installed in the model to intuitively analyze the characteristics of formation displacement change and stress distribution. A total of 10 rows of survey lines are arranged for the whole overlying stratum model, and 24 survey points are arranged on each survey line, of which the interval between transverse adjacent survey points is 10 cm, and the distance between vertical survey lines and 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. The simulated displacement of the roof at different positions of the coal seam is similar to the measured data in the laboratory.The data set contains 240 sets of data.
