In order to further reveal the propagation attenuation laws of blasting vibration based on damage accumulation, author designed damage accumulation and blasting vibration testing experiment of concrete block. The results show that the damage value of the measured points went on increasing with the increase of the blasting times. The damage value can be divided into two stages in middle and far area, a slow increase at early stage and a quick increase at later stage. Single blasting vibration velocity of measured points decreased with the distance increasing, and vibration velocity of measured points in the near area decreased faster than the middle and far area. The blasting vibration velocity of measured points went on decreasing generally with the increase of the blasting times, and the vibration velocity near the explosion source decreased rapidly, But In middle and far area, the velocity decreased in small amplitude and slowly. And with the increase of the blasting times, the vibration velocity has the process of sudden increase. The vibration attenuation coefficient increased slowly with the increase of blasting times, however, the value of  reduced, and both of them had a process of small amplitude distortion. Under the condition of repeated blasting, the determination of the safety threshold and propagation attenuation laws（the value of  and ）of the blasting vibration should take full account of the blasting vibration damage accumulation effect.
