深部高应力巷道支护工艺分析

Supporting technique analysis of deep and high pressure roadways

深部巷道地压大,岩石稳固性差。通过实施光面爆破、加强工艺管理,爆破质量和进度均取得突破。本文对光面爆破和喷锚网支护等工序进行论述,对施工过程中的经验与不足进行分析。从施工者角度阐明对"抗和让"的辩证关系,对类似支护条件下的工程施工具有参考意义。

It has high pressure,and the rock stability is poor in deep-seated roadway.The blasting quality and progress has got great breakthrough by using smooth blasting and strengthening process management.In this paper the smooth blasting and shotcrete and anchor net support technique,the experience and lack during construction were analyzed.The relationship of ＇anti and let＇ was clarified from the constructor＇s view.It has a reference value for the project with similar support conditions.
