Because the top slate layer of the work surface presents the characteristics of periodic fracture, and the fracture period of the top slate layer in different areas of the work surface is different, it is necessary to predict the hydraulic support load of a fracture period of the top slate layer, so as to provide sufficient time for the disaster prevention and control of the top plate of the work surface. The above-mentioned ARIMA model and SARIMA model are used to predict the load of multiple cycles of the hydraulic support, as shown in Figure 13.
