摘要
锚杆支护已经成为矿山巷道、隧道及基坑工程支护的主要形式之一。伴随着地下空间工程的不断发展,大量使用的锚杆对于地下空间污染情况也愈发严重,可回收锚杆技术应运而生。本文按结构将可回收锚杆分为机械式、组合式、螺旋式和热熔式4大类,介绍了矿山巷道中可回收锚杆技术研究进展,指出了其存在问题,展望了其发展趋势,对可回收锚杆技术推广应用具有一定指导意义。
Anchor support has become one of the main forms of support for mining roadways,tunnels and foundation pit projects.Along with the continuous development of underground space engineering,the massive use of anchor rods for underground space pollution has become more and more serious,and the recyclable anchor technology has emerged.This paper classifies the recoverable anchor rods into four major categories:mechanical,combination,spiral and hot fusion,according to their structures.It introduces the progress of research on recoverable anchor rod technology in mine roadways,points out their problems and prospects their development trends,which is of some guidance for the promotion and application of recoverable anchor rod technology.
