青山煤矿压风系统改造的施工方法

摘要

The paper introduces the construction method for the transformation of compressed air system in Qing‐shan Colliery by lowering the prefabricated piping section by section ,connecting at the hole mouth and reinfor‐cing with grouting after drilling between the upper and lower level with raising boring machine ,which is novel , green energy -saving ,efficient and safe ,and can be applied in the transformation project of other mine auxiliary system .%青山煤矿压风系统改造的施工方法：采用反井钻机在上下水平之间钻孔后，将预制管路逐节下放，并在孔口进行连接，最后注浆固定。该设计与施工方法新颖、绿色节能、高效安全，可用于其它矿山辅助系统改造工程。
