In this paper, based on the industry standard and the application situation and naming method of the product models of rock drilling rigs from the main domestic and foreign manufacturers, the compilation principles and methods of the product models of rock drilling rigs and the application and

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 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
