钻孔导井法施工竖井在呷村矿溜矿井的应用

Application of the Drilling Pilot Shaft Method for Shaft Construction in the Xiacun Mine

摘要:

竖井传统施工方法进度慢，施工难度大，成本高。当其有下部通道时，选择钻孔导井法施工，则可以大大缩短工期，降低成本，具有明显的优越性。以呷村矿山溜井工程实践为例，探讨了钻机导井法施工竖井的关键工艺。

Abstract:

Traditional shaft construction method was difficult with slow progress and high cost. Drilling pilot shaft has the obvious superiority to greatly reduce the construction period and the cost for a project with channel in lower part. This article discussed the key technology of drilling pilot shaft for shaft construction by the case of Xiacun mine.
