The invention discloses an efficient open air deep hole blasting packing operation device which comprises a first circular truncated cone, wherein a second circular truncated cone is fixedly connectedonto the top of the first circular truncated cone in an inserted manner, a movable table is connected above the second circular truncated cone through a plurality of springs, and a semi-spherical drain screen is rotatably mounted on the movable table through a bearing. The efficient open air deep hole blasting packing operation device disclosed by the invention can improve the efficiency of the packing operating link effectively, so that the integral construction efficiency is improved, and the safety problem generated by the packing problem is avoided effectively. Relative large stuffing canbe prevented from entering a blast hole to crush a detonating tube by means of filtration by the drain screen, and meanwhile, detonating slungshots and influence on the detonating effect can be further avoided when the relati
