Abstract: In order to study the influence of blasting vibration on the ground construction facilities in Luohe iron mine,the field test method is adopted,based on Sadovski formula and considering the influence of elevation difference.The data processing method of linear regression is adopted to fit the propagation law of underground blasting.The results can predict the impact of blasting scale and blasting position on private houses,and provide a basis for taking measures to control vibration in blasting.
