摘　　要：针对井筒基岩段硬岩段施工中,受条件限制无法采用钻爆法掘进时,采用挖掘机配合液压破碎锤、气动破碎机、液压劈裂机作为施工机械的新型机械化掘进作业方式,与传统作业方式相比提高了掘进施工速度,为类似工程积累了施工经验。In the shaft bedrock section of the hard rock in the period of construction,restricted by condition cannot advance by drilling and blasting method,by excavators and hydraulic hammer,pneumatic crusher,hydraulic fracturing machines as a new type of mechanized drivage construction machinery operation way,compared with the traditional practices improve the construction speed of excavating,accumulated construction experience for similar projects.
