矿山巷道超前支护中空注浆锚杆施工技术探讨

摘要

Hollow grouting anchor commonly used in nursing advance ahead of hollow grouting anchor for the system in general and composite lining the roadway arch radial bolt , mainly used in geological conditions of moderate -good rock permanent system support and advanced support.Based on the engineering example ,describes the construction process forepoling construction hollow grouting anchor in mining engineering.%中空注浆锚杆常用于预支护的超前中空注浆锚杆和用于一般巷道复合式衬砌拱部的系统径向锚杆，主要应用于地质条件中等-良好的围岩永久系统支护和超前预支护。文中根据工程实例，介绍在矿山工程中超前支护施工中中空注浆锚杆的施工工艺。
