| Abstract: | The key points of the application of and economical analysis on tunnel excavation by hydraulic rock drilling jumbos are discussed. The causes for the overbreak induced by hydraulic rock drilling jumbos and the collection of the basic data needed for economic analysis are presented and analyzed. The analysis results show that hydraulic rock drill- ing jumbos are suitable, rational and economical for the excavation of long railway tunnels. |
