Low-detonation-velocity explosive smooth blasting construction method

The invention discloses a low-detonation-velocity explosive smooth blasting construction method, and relates to the technical field of smooth blasting. The smooth blasting construction method for the low-detonation-velocity explosives comprises the following specific operation steps that S1, a pneumatic charging device is connected to an underground mine air pipe, and accumulated water and accumulated slag in a hole are cleaned through the pneumatic charging device; s2, using an electronic detonator and a common 32mm-diameter cartridge to manufacture an initiating explosive package, and filling the initiating explosive package into a peripheral hole by using a tamping bar; according to the smooth blasting construction method for the low-detonation-velocity explosive, a specially-made low-detonation-velocity ammonium nitrate fuel oil explosive coupling charging structure is adopted to replace a traditional 32 mm-diameter second rock emulsion explosive interval charging structure for charging, meanwhile, a pneu
