With the coal mine gradually moving towards deep mining, the increase of rock burst on the roof and floor of the roadway is followed by the increase of tunneling risk and low tunneling efficiency of hard rock roadway, and the existing roadway deformation is increased, roof caving is prominent and

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
