【摘要】 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。更多还原

【Abstract】 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.更多还原
