Abstract
An automatic support device for resisting rock burst in mines is provided, which includes bases symmetrically distributed, sliding frames are slidably connected to the bases, hydraulic rods are fixedly connected to the bases, and telescopic ends of the hydraulic rods are fixedly connected to the adjacent sliding frames. The sliding frames are fixedly connected to brackets, and the brackets symmetrically distributed are provided with a main support plate, on which pushing rods are provided. The device can slow down the impact force of the device when rock burst occurs in the mine, at the same time, it plays a supporting role in the mine, ensuring the stability of the roof of the mine.
