【摘要】 爆堆矿岩块度分布是评价爆破效果重要的指标之一。准确地测定出爆破后矿岩的块度分布,既是正确评价爆破质量的前提,又是建立爆破块度计算模型和优化爆破参数的基础。关于爆堆矿岩块度分布研究已经历了半个多世纪。本文对于爆堆矿岩块度分布的现有的测试方法,进行了系统的归纳总结,介绍了爆堆矿岩块度分布测试方法的发展历史和研究现状,将有助于该领域的深入研究。更多还原

【Abstract】 Distribution of the site of exploded ore is one of the important targets for evaluating the explosion effectAccurately measuring the distribution of ore sire after explosion is the prerequisite for correctly evaluating the explosion quality and also the basis for setting up calculation model for the exploded ore size and optional explosion parameters as well.This article suncmarizes the existent measuring methods about the distribution of the site of exploded ore and introduces the development history and the present situation of the measuring methods,which will be benefit for further research in this respect.更多还原
