| 摘 要： | 地面振动是爆破产生的副效应之一，爆破中，相当一部分能量通过其产生的地面振动而被消耗，从而导致矿山产量大降，甚至影响矿山的发展．本文处理并分析了在伊朗Kerman 省Sarcheshmeh铜矿11次爆破记录到的57个三分向地震图．这些数据通过数字化地震仪PDAS-100记录得到，并使用DADISP软件加以分析．最后，重新考察了影响地面振动的爆破参数，比如炸药的重量和种类、结构物与爆破点的距离、爆破延时等，并研究了它们对峰值质点速度（vPP）的影响．在此基础上，确定了合适的爆破延时及炸药种类．通过研究这些数据，为Sarcheshmeh铜矿作出了vPP与换算距离之间的关系图．有了这样的关系图，就能够确定结构物的安全距离及相应的炸药数量．

| Abstract: | Ground vibration is one of the side effects of blasting, in which way considerable amount of explosive energy is exhausted, and causes decrease in production and even decline in mine development workings. In this study, 57 recorded 3-C seismograms from 11 blasts in Sarcheshmeh copper mine, Kerman, Iran, were processed and analyzed. These data were recorded by digital seismograph PDAS-100 and analyzed by DADISP software. Finally, blasting parameters, such as explosive weight and type, distance between the structures and blasting site, blasting delays, affecting ground vibration are reviewed and their influence on Peak Particle Velocity (vPP) are studied. Based on this study, suitable detonation delays and explosive type is determined. Considering these data, a graph of vPP versus scaled distance for Sarcheshmeh copper mine is prepared, by the help of which, safe distance for structures and accordingly explosive quantity could be determined. |
