Abstract
Taking the construction of diversion tunnel in the lower reservoir of a pumped storage power station as an example,this paper discusses the application of EBZ260 boom roadheader in the construction of small section hydraulic tunnel,and makes a comparative analysis with the traditional drilling and blasting method from the aspects of construction safety,quality,progress and economy.The results show that compared with the traditional drilling and blasting method,the construction of boom roadheader has less disturbance to the surrounding rock,which can effectively control the overbreak and underbreak,and the construction quality is easy to control,the construction is safer and the construction cost is lower.The construction experience can provide reference for similar engineering construction.关键词
