English	Chinese
Current blast fragmentation models tend to focus on the coarse end of the fragmentation curve because of the impact of poor fragmentation on excavation performance, and hence excavation costs	由于岩石破碎不理想、影响到开采计划的实施、进而影响到开采成本、常用的爆破破碎模型只能对破碎曲线进行粗略分析
More recent focus has been provided on the finer end of the fragmentation curve to explore the potential of blasting to influence the subsequent crushing and nulling performance of metalliferous ores	近来、人们把研究的重点大多放在破碎曲线的细端、以探索爆破的潜力、因为爆破的结果会影响到含金属矿石随后的粉碎和加工制造过程
The minimum description of rock mass properties that influence blast performance includes the density, strength, stiffness and frequency and nature of discontinuities, together with an understanding of the variability of these parameters across the blasting area	影响爆破行为的岩体特性描写的最少、包括非连续面的密度、强度、硬度、频率及自然属性、而且对爆破区域内这些参数的可变性了解的也最少
