| 摘 要： | 岩石爆破块度除了受岩石和炸药性质影响外，还受到装药结构、爆破参数和爆破技术等的影响。在实际的爆破工程中，为了不同的爆破目的，需要采取不同的爆破方法和参数。采用砼和天然岩石试样，通过改变不偶合系数、炸药单耗、爆破参数和填塞条件等参数进行模拟爆破实验，对爆破后的块度进行筛分统计分析，以优化爆破参数和实现对爆破块度的控制和预测。 |
| 关 键 词： | 块度控制 爆破参数 装药结构 不耦合系数 炸药单耗 |

| Abstract: | The rock fragmentation is influenced by some factors as charge structure,blasting parameter and blasting technique besides the properties of rock and explosive.The different blasting parameters are applied to different condition in the practice.The blasting tests are performed by changing blasting parameters such as uncoupling coefficient,specific charge and stemming length on reinforced concrete and nature rock samples,then the sieve and statistical analysis of the rock fragmentation was taken,which optimi... |
| Keywords: | fragmentation control blasting parameter charge structure uncoupling coefficient specific |
