Facing the challenges of high-speed railway tunnel projects, which involve complex geology, high safety risks, and strict quality requirements, a mechanized construction technology system for long tunnels has been proposed. It introduces key equipment and technologies like the three-arm rock

This article, in combination with the construction characteristics of the No. 3 inclined shaft of Fengshun Tunnel, provides a detailed explanation of the construction technology of the three-arm rock drilling jumbo. It compares the excavation construction of the rock drilling jumbo with traditional

This article compares manual operations and multi-arm drilling jumbo blasting in terms of technology, quality, drilling, economy, and safety, mainly providing a detailed comparison from aspects such as construction processes, construction characteristics, and personnel allocation. It ultimately

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

To address issues such as the inability of humans to install long anchors in weak surrounding rock tunnels and the high cost of specialized foreign equipment, a technical method for installing self-advancing long anchors using a drilling jumbo is proposed, taking the soft rock large deformation

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

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
