在采矿作业中,岩石破碎,例如爆破以后的粒度分布对于计算爆破块度的平均粒径,比表面积都起着重要的作用。而且在爆破质量的评价和爆破优化的设计中也是不可缺少的内容。但是,若用函数关系式简明地表示岩石破碎的粒度分布也是很困难的。因为,这些破碎岩块的形状不规则,分布范围广泛。本研究的目的,在于寻求岩石在承受诸如凿岩、爆破这类冲击载荷作用时的粒度分布函数。
In mining operations, rock fragmentation, such as the particle size distribution after blasting, plays an important role in calculating the average particle size and specific surface area of the blasting block. But also in the blasting quality evaluation and blasting optimization design is also an indispensable content. However, it is also difficult to concisely represent the particle size distribution of rock fragmentation by a functional relation. Because these broken rocks are irregular in shape and have a wide distribution. The purpose of this study is to find the particle size distribution function of rock under impact loads such as rock drilling and blasting.
