综采工作面大断面切眼全锚支护的设计与施工

The Plan and Construction of Bolting in Large Section of the First Cutting Roadway

大断面切眼采用全锚支护技术可行 ,经济合理 ,比传统的木棚支护强度高 ,效果好 ,有效地解决了切眼支护的问题 ,掘进速度也大大提高。屯兰矿近年来在切眼内全锚支护的实践 ,也反映了这种支护方式的安全性和可靠性。本文以屯兰矿 2 2 1 0 1工作面为例 ,详细介绍了大断面切眼全锚支护的施工及设计特点。

It is economy and feasible by adopting bolting in large section of the frst cutting roadway ,the support intensity is higher,the effect is better than that of traditional wooden.the first cutting roadway support is resolved effectively,the tunnel speed is rised greatly.This paper introduces the construction and plan bolting of large section of the first cutting roadwayin Tunlan 22101 coal face.
