【摘要】 岩石爆破工程中,不可避免的会产生一些超径大块石,这些大块石一般质量都非常好,能满足砼对骨料质量的要求,但一般情况下都要进行二次爆破才能满足粒径要求。本文介绍了白石水库工程超径大块石二次爆破过程中工程技术人员经过技术研究和实验,利用废弃的导爆管与价格低廉的火雷管组合制成了技术上可行,操作上简单的新的引爆装置的成功经验。更多还原

【Abstract】 In the rock blowing up engineering,some over radius rocks are produced inevitably,which have the good quality to satisfy the requirement of the aggregate quality of concrete,but the second blowing up is needed.This paper introduces the research and test for the simple igniting set for the second blowing up of over radius large rocks in Baihe reservoir,the technique which has the successful experience and has feasibility on technology and handling simple,combined the igniting set with the lead burst pipe out of date and exploder low price.更多还原
