爆破振动破坏效应鉴定方法的研究

Research on Identification Method of Blasting Shake Destroy Effect

文章结合一起由爆破振动破坏而引发的实际案例,进行了系列实验研究,对爆破振动破坏效应的鉴定方法进行一定的探讨和研究。爆破振动研究实验采用硐室内集团装药,监测距离为400 m,装药量从5 kg开始系列递增。通过实验并归纳实验结果,得出了公式Vm=46(Q1/3/R)1.6,并通过实践验证,认为该公式作为花岗岩、石灰岩等介质条件下小药量爆破振动破坏效应鉴定依据是合理的。

Identification method of blasting shake destroy effect is studied through series of experiments according to a practical case of blasting shake destroy. Experiments are taken under the condition of aggregative dynamite, a distance of 400m, and the initial dynamite quality of 5kg is gradually increased. The formula Vm=46（Q^1/3/R）1.6 can be concluded through experiment results. The conclusion is thought to be suitable for being used as the identification method of blasting shake destroy effect for small dynamite quantity experiments on the ground of granite, calcareousness and other mediums.
