Abstract：For solve the problem efficiently of adjacent buildings might be destroyed in the open pit deep hole blasting vibration. Firstly blasting vibration had been real-time monitoring two times by using blasting vibration signal test system in an open limestone. And monitoring data of blasting vibration were processed by the one variant linear regression analysis under the former blasting parameters. Attenuation law of blasting vibration wave propagation was obtained in this stope. At the same time using the method of dynamic finite element analysis, dynamic response of open pit deep hole blasting vibration on adjacent building was investigated under blasting load. Finally, dynamic response of numerical analysis and field monitoring was comparative analysis. The studies show that oscillogram of blasting vibration velocity are obtained by the dynamic response of numerical analysis method which basically identical with field monitoring; Dynamic response of numerical analysis result of blasting vibration velocity and acceleration are basically similar in change of laws and trends; Favorable results can be achieved for reducing blasting vibration when initiation sequence and blasting direction of open-air blasting are changed.
