摘　　要：基于冬瓜山铜矿开采技术条件与采场生产实际,为确定大直径深孔采矿中地震波的传播规律,评价其对围岩体稳定性的影响,对采矿爆破引起的临近巷道围岩体质点振动进行现场测试。根据现场测试数据的统计和回归分析,参考萨道夫斯基公式,回归得到表征振动传播规律的经验公式,并分析了现场爆破振动频度特征,揭示了该矿地下采场爆破振动的传播规律,对指导矿山安全高效开采有一定指导意义。According to the mining technology conditions and stope production situation of Dong- guashan copper mine, in order to determine the law of large-diameter long-hole mining seismic wave prop- agation, 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 a- nalysis results of the fileld data and the Sadaovsk formula. So, the law of underground mining blasting vi- bration 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.
