某石料厂石材开采爆破震动测试与分析

Test and Analysis of Blasting Vibration in Exploition of Stone in a Stone Materials Factory

为了确定某石料厂石材开采时爆破震动衰减规律及其对邻近村庄建(构)筑物的安全影响大小,对该厂某次开采爆破进行了震动测试。通过分析实测数据,找到适合于该厂石材开采爆破的k、α值以及最大单响允许起爆药量,得出一系列结论,为其预测爆破地震强度和采取降震减震措施提供了理论依据。

To determine the attenuation law of blasting vibration and the impact on security of near building （ structures ） in the exploition, the author tested a vibration in exploiting blasting in a factory. By analyzing the data of surveying, the author finds the suitable k, α and a maximum explosive quantity of single blasting for exploiting stone material in the factory, and draws a series of conclusions, offers theoretical foundation for predicting intensity of blasting vibrations when taking measures to lower and reduce blasting vibrations.
