241 under static load (average 3.63 kN). The load on the side guard of the canopy increased periodically under side-push impact. And under rear-push impact, the load on the shield beam was highest in the upper incline section, followed by the middle, and smallest in the lower section. Support instability and tipping can be triggered when loading leads to roof rupture, indicating the necessity for enhanced anti-overturning and anti-sliding control in steeply dipping faces. Digital twin technology provides crucial theoretical support and an experimental verification means for the dynamic stability control of supports.
