Coarse – phrases

English	Chinese
coarse fragmentation	粗粒岩爆
coarse size	粗粒度
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
moderately coarse	中间粒度的
The coarse end of the predicted fragmentation size distribution is often over-estimated because the fragment top size is not influenced by the structure of the rock mass in the model	对所预测的碎岩粒度分布的粗端往往给以过高估计、这是因为碎岩最大粒度不受模型中岩体结构的影响
The coarse end of the resulting fragment size distribution is influenced by the insitu rock mass structure and the spatial distribution of the explosive within the rock mass	破碎粒度合成分布曲线受原位岩体结构的影响、也受岩体内炸药空间分布的影响
