抽水蓄能电站勘探平洞掏槽爆破方法研究
Study on the Method of Excavation and Blasting for Exploration Tunnels in Pumped Storage Power Stations
摘要
Abstract
In order to solve the problem of low footage in a single cycle of drilling and blasting tunnels for pumped storage power station exploration,and speed up the progress of engineering geological survey and construction of pumped storage power stations,a new method of"large-diameter hollow hole ring+barrel multi-stage"cutting is proposed,and the rationality of its parameters and rock breaking mechanism are analyzed.Engineering application results show that the cutting method can increase and stabilize the single-cycle average footage and monthly average footage of pumped-storage exploration tunnels(small cross-section)to3.12 m and280 m respectively.The method has significant applicability and superiority in rapid construction.At the same time,it has extremely high promotion and applica-tion value in small-section tunnels with rapid excavation requirements such as pumped-storage exploration tunnels,mine rock tunnels,pumped-storage drainage corridors,etc.关键词
