This paper focuses on the mining tunnel of the Shenzhen-Huizhou intercity Dapeng branch line, and the goal is to analyze the technical feasibility and economic benefits of mechanized drilling and blasting method in the construction of mining tunnels.we worked to improve and adjust the blasting

Based on the Fengshuling Tunnel of Quli Railway, the factors of tunnel excavation construction efficiency and the applicability evaluation of the three-arm rock drilling rig in three different excavation conditions of long and large tunnels were analyzed. The results show that the surrounding rock

A parallel pilot tunnel with a section size of 6.5m × 6.5m in a railway tunnel is taken as an example． In view of the practical engineering problems such as the inability of the three-arm rock drill to realize the inclined cut and the long ventilation time after blasting due to the limitation of

In order to solve the problem of slow tunneling speed of hard rock roadway in metal mines，and in response to the call of "mechanized replacement and automation reduction"，more and more mines use drilling rigs to replace manual hand-held air drills to improve perforation efficiency，thereby improving

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

This article takes the exit of the Xiaofeng Tunnel of the Yixing Railway as an example. In view of the problem of reasonable allocation of three-arm rock drilling rig operators during tunnel construction, practical optimization and improvements are made from the two aspects of construction process
