However, the existing structure of the tunneling and anchoring integrated machine has the problem that the distance between the forefront row of jumbolters and the head-on position is more than 3 meters, namely: the tunneling head always has an empty top of more than 3 meters. The empty roof condition has no problem when the roof conditions are good; however, once the roof condition is slightly broken, the jumbolter arranged on the tunneling and anchoring integrated machine cannot be used, and the supporting operation can be carried out only by manually holding the drilling machine to the position of the tunneling head in the empty-roof state, so that not only is the tunneling efficiency not kept up, but also the passive manual supporting operation is more dangerous than the manual supporting operation carried out by using the common tunneling machine.

Therefore, the improvement of the airborne drilling and anchoring device of the existing tunneling equipment is needed.
