High impact and large transformation resisting energy absorption anchoring tray component and energy absorption anchoring method thereof

Abstract

The invention discloses a high impact and large transformation resisting energy absorption anchoring tray component which comprises a common flat anchoring tray, a conical steel pipe and a dish-shapedtray arranged in turn from top to bottom, wherein the conical steel pipe is a conical barrel structure with thin top and thick bottom; the upper end of the conical steel pipe is fixedly connected with the lower surface of the common flat anchoring tray; the lower end of the conical steel pipe is fixedly connected with the upper surface of the dish-shaped tray; a first anchor rod through hole is formed in the common flat anchoring tray; a second anchor rod through hole is formed in the dish-shaped tray; the center lines of the first anchor rod through hole, the conical steel pipe and the second anchor rod through hole are overlapped. The invention also discloses an energy absorption anchoring method of the high impact and large transformation resisting energy absorption anchoring tray component. The high impact and large transformation resisting energy absorption anchoring tray component disclosed by the invention has the characteristics of rare deformation unloading or breakage, strong deformation adaptability, continuous yielding, convenience in mounting and the like,the support cost of a deep rock grooundpressure roadway of a mine is reduced, the safety factor of production in the mine is improved, and the effectiveness and safety of a deep roadway surrounding rock anchor rod support system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of support equipment for mine safety production, and in particular relates to a high-impact, large-deformation energy-absorbing anchoring tray assembly and an energy-absorbing anchoring method thereof. Background technique [0002] Mine dynamic disasters such as rock burst and coal and gas outburst are major disasters encountered in the mining process, and the resulting impact damage to the roadway surrounding rock is one of the key issues affecting mine safety. Because bolt support has the advantages of high utilization rate of roadway section, convenient construction, low cost, fast recovery speed, etc., it has become a safe and efficient main support method for mine roadways, and has been widely promoted and applied in mine roadways in my country. The anchor tray is an important part of the anchor support system and an indispensable part of the anchor system to generate anchoring force. Its function is to...
