摘要(Abstract):

为修建浙江省玉环县里墩水库 ,需开采石料。根据爆区的地形特点、环境特征等因素 ,采用了条形药包松动硐室爆破。本文介绍了在复杂环境条件下硐室爆破的设计和施工 ,概述了这次爆破的难点和具体方案 ,讨论了爆破参数的选择、药量计算和起爆顺序。同时 ,对爆破安全性进行了预估 ,并指出对条形药包的端部装药应引起足够的重视
In order to construct Lidun reservoir in Yuhuan county,Zhejiang province,exploitation of rock material had to be carried out According to such factors as the topography features of blasting area and environmental characteristics,a loose chamber blasting with linear charges was adopted In this paper,the design and construction of chamber blasting in complicated surroundings were introduced,the difficult points and concrete scheme of this blasting outlined,and the selection of blasting parameters,calculation of charge mass and initiating sequence discussed At the same time,predication of blasting safety was performed And it was pointed out in this pape that a great attention should be paid to the end load of a linear charge

关键词(KeyWords): 硐室爆破;条形药包;空腔比;爆破安全
