To enhance the safety and efficiency of mechanized drill-and-blast construction in highway tunnels and address challenges such as difficult mechanized construction and overbreak control in poor rock mass conditions, this paper investigates existing problems and proposes adaptive strategies. Current

Under the background of intelligent construction in engineering, tunnel construction technology is transitioning toward systematic intelligence. This paper takes the Donghanjia Tunnel of the Shenbai High-Speed Railway as an example, integrating the ZYS113 fully computerized three-arm rock drilling

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
