摘要(Abstract)：
综述了集中药包和条形药包的应用条件 ,介绍了硐室爆破中条形药包的优越性、药包的分类、药包间距以及装药量和压缩圈半径的计算 ,论述了条形药包设计时应注意的问题、条形药包布置时有关问题的处理办法、起爆技术以及堵塞工作中应注意的问题。这些可为硐室爆破工程作参考
In this paper, the application conditions of concentrated charges and strip charges are surveyed; the advantages of strip charges, charge classification, the calculation of load, charge space and crush zone radius in chamber blasting are introduced; the issues which should be considered during design of strip charges, the methods of treating some problems during layout of strip charges, priming technology and the notices in operation of the stemming are discussed. These are available for reference for chamber blasting projects.
