摘要(Abstract):

采用条形药包与集中药包小间隔组合技术处理条形药包硐室爆破山体端部药包 ,可以控制端部药包的爆破安全问题和改善端部岩石的破碎效果。该技术的端部集中药包药量计算引入了折算系数Kz。两个爆破实例的介绍说明了这种技术的使用方法和其爆破效果。
In chamber blasting with linear charges,concentrated charges with a small space to the end of a linear charge are disposed as the hill side charge With this technique,the blasting safety on explosion of the hill side charge can be guaranteed and the fragmentation of the hill side rockmass highly improved In this technique,a conversion coefficient K z is introduced for calculation of the weight of the hill side concentrated charge Two practical examples cited in this paper have illustrated the use of this technique and its effectiveness
