The fully computerized three-arm rock drill jumbo is currently the most advanced equipment for mechanized tunnel excavation using the drill-and-blast method. It has unparalleled advantages in the excavation of Class III and higher hard rock tunnels. However, its technical, economic, and

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
