The utility model discloses a micro vibration blasting device for a deep-hole bench. Segmented explosive loading and segmented blocking are realized in a deep-hole blasting hole at intervals; a hole opening is a long block; millisecond differential delay detonators at different segments are respectively arranged in an explosive loading section in the hole and are led to the hole opening; a millisecond differential delay detonator is arranged in each hole outside the hole; the millisecond differential delay detonators are serially connected to form a single-hole and single-sound blasting network; each millisecond differential delay detonator outside the hole is connected with each millisecond differential delay detonator in the hole, which is led from the hole opening, and is connected with an electric blasting detonator and a blaster. The micro vibration blasting device disclosed by the utility model is suitable for blasting the deep-hole bench with a special vibration requirement (the vibration speed of a mass point is 0.2cm/s) in a near residential area; the single-sound explosive quantity is reduced to the maximum extent and the micro vibration blasting is realized. The micro vibration blasting device disclosed by the utility model has the advantages of reasonable design, strong practicality, increased efficiency and increased construction speed.
