摘　　要：根据金山店铁矿地表爆破振动监测数据,运用统计学方法得到了金山店铁矿生产爆破地表振动衰减特性的萨道夫斯基公式。通过分析勘探线测点布置剖面图得到张福山采区不同开采水平与受保护的建(构)筑物(监测点)之间的最小爆心距,基于衰减特性,在考虑1.5倍和2.0倍安全振动速度条件下,计算金山店铁矿张福山采区3个区域的最大安全单段起爆药量范围,并给出此3个区域在后续生产中的最大单段起爆药量推荐值,为矿山生产爆破减振提出了有效措施。Saudorsky formula for the vibration attenuation char- acteristics in blasting operation in Jinshandian Iron Mine is ob- tained by a statistical method based on its surface blasting vibra- tion monitoring data. The prospecting line profile figures of moni- toring points is analyzed to obtain the minimum blast center dis- tances between the different mining levels in Zhangfushan Mining Area and the protected buildings（structures, monitoring points ）. In light of the attenuation characteristics, considering the condi- tions of safety factors of 1.5 times and 2.0 times vibration veloci- ty, the maximum safe single--section amount of initiating explo- sive in 3 areas of the mine could be calculated and their recommen- ded values are given in the subsequent production to provide effec- tive measures for reducing the blasting vibration of the mine.
