竖井施工中地面预注浆技术的分析

摘要

The geological conditions of the shaft is different, the pre-grouting scheme and the construction process will be different. Taking a mine of Huainan as an example, the paper emphatically introduces the parameters of pre grouting, and analyzes how to prevent and correct the deviation and deviation of the grouting hole in the construction of the shaft, and provide valuable experience for the construction of the shaft.%竖井所处的地质条件不同，所采用的预注浆方案及施工工艺也会不同。本文以淮南某矿为例，着重介绍了预注浆相关参数的确定，并分析了竖井施工中如何对于注浆孔进行防斜、纠偏，为今后的竖井施工提供了宝贵的经验。
