| Abstract: | 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 |
| Keywords: | Chamber blasting Linear charge Concentrated charge Conversion coefficient |
