Excavation operation is an important proces in the excavation of tunnels and passages in metal and non-metalunderground mines, providing necessary channels and conditions for subsequent mining, ventilation, power supply, safetymanagement, and other work. It is an important link in mining. Therefore

This paper takes the Changyang Tunnel project of the newly constructed Yichang-Fuling High-Speed Railway in Hubei Province as the research object, and conducts a comparative study on the comprehensive effectiveness of fully computer-controlled three-arm rock drilling jumbos and traditional manual
