At present, the construction of the New Austrian Tunnel Construction Method (NATM) is still dominated by labor-intensive production. Although the three-arm rock drilling rig has the ability of mechanical automated drilling, it has not yet completely replaced the air-legged pneumatic drill. Combined

In the construction of highway tunnel projects, drilling and blasting is the most widely used construction technology. Its main principle is to use explosives to blast for excavation. In the charging process, blasthole drilling is an important part. The use of intelligent rock drilling rigs can
