采用冻结法施工的立井井筒在冻结壁解冻后，冻结管与周围岩体之间的环形空间将成为沟通上、下部含水层的垂向通道，严重威胁着矿井的生产安全。本文介绍了立井井筒冻结管射孔注浆技术在巴彦高勒矿井的实践与应用，为解决相似条件下立井井筒解冻水害提供了借鉴与指导作用。

After thawing of the vertical shaft freezing pipe by using freezing construction, the annular space between freezing pipe and rock mass will form the vertical channel communicates upper and lower aquifers, which will seriously threaten the safe production of coal mine. This paper introduces the practice and application of penetration and grouting technologies with vertical shaft freezing pipe in bayangol coal mine, which will present the optimization and upgrading proposal on solving the problem of thawing of the vertical shaft freezing pipe under similar condition.
