各个矿山地下采矿的矿岩爆破块度分布是不同的,它取决于矿岩条件和采矿方法,而且与所用的炸药量有关。深入研究爆破矿岩的块度分布即岩石爆破破碎质量对矿山生产率和成本的影响,曾被瑞典采矿研究基金会列为1981～84年度的研究项目之一。很清楚,各矿矿岩块度和成本的关系很不相同。然而在研究地下矿爆破岩石的块度变化时,务必考虑一些影响因素。较好的块
The ore block blasting fragmentation distribution is different for each mine underground mining, which depends on the ore rock conditions and mining methods, but also on the amount of explosives used. In-depth study of the block size distribution of blasting ore rock, that is, the impact of rock blasting quality on mine productivity and cost, was listed as one of the research projects in 1981-84 by the Swedish Mining Research Foundation. Clearly, the relationship between ore block size and cost is very different. However, when studying the changes in the degree of rock mass fragmentation in underground mines, it is important to consider some factors. Better block
