Abstract: According to the mining technology conditions and stope production situation of Dongguashan copper mine,in order to determine the law of large-diameter long-hole mining seismic wave propagation,and evaluate the effect on the stability of the surrounding rock,so,the field blasting vibration drawing near roadway surrounding rock caused by mining blasting is monitored.The experience formula and the characteristics of blasting vibration frequency are obtained according to the statistic datas,the analysis results of the fileld data and the Sadaovsk formula.So,the law of underground mining blasting vibration propagation is revealed.The research results in this paper is proved that,it has guiding meaning to keep safety and high efficiency production of the mine. 　　

Key words: Large diameter long hole, Vibration testing, Regression analysis
