The invention discloses a quickly mounted efficient energy-absorbing mining anchor rod which comprises an expansion shell, a rod head, a rod body, a tray, an anti-seismic buffering material, a nut and a rod
tail, wherein a tooth-shaped bulge is arranged on the outer surface of the expansion shell; matched threads are respectively arranged on the inner surface of the expansion shell and the outer surface of the rod head; a tapered bulge is arranged in the expansion shell; a tapered groove is arranged at the top of the rod head; a vertex angle of the tapered bulge is more than the vertex angle of the tapered groove; the thread is arranged on the rod
tail; and the tray and the anti-seismic buffering material are respectively sleeved on the rod
tail and are positioned and pre-tensioned by the nut. According to the invention, quick loading is realized by the anchor rod; mounting process is simplified; mounting time is shortened; driving speed is increased; the anti-seismic buffering material has a compressing buffering function when rock is burst, so as to effectively
resist the
dynamic loading effect at rock
bursting moment; a certain anchoring force is kept by the anchor rod; and the anchor rod is prevented from being broken and invalid. Besides, the quickly mounted efficient energy-absorbing mining anchor rod has the beneficial effects of simple structure, convenience in mounting, high
operability, and the like, and is widely applied to underground supporting for deep well.
