摘要
近年来,煤矿巷道支护技术得以快速的创新及发展。锚杆支护不仅具有悬吊的作用,甚至还能够利用预应力的扩散以及预紧力的高强度施加,与围岩共同构成支护体,继而将围岩自身能承受的能力予以充分的调动。鉴于此,详细论述了锚杆支护的本质含义和基本作用机理,并阐述了设计锚杆支护的方法及相关的应用软件。
In recent years, the technology of supporting technology in coal mine is developing rapidly. Anchor bolt plays the role of suspended, and by using prestressed diffusion and pre tightening force high strength applied, forming a support with surrounding rock, and then the rock itself withstand ability can be fully mobilized. In view of this, this paper discusses the essential meaning and basic mechanism of the bolt support, and expounds the design method and application software of the bolt support.
