With the continuous improvement of the design and manufacturing technology of large-scale tunnel machinery and its intelligence, the large-scale mechanized construction technology of drill-and-blast tunnels is becoming more and more mature. In this paper, the fully computerized 3-arm rock drilling

In order to effectively prevent tunnel construction safety accidents and ensure high-quality construction of major projects, traditional tunnel construction methods are gradually transforming into large-scale mechanization. The three-arm rock drilling rig is widely used due to its advantages of fast
