随着南非矿山使用炸药品种的增多,要求对爆破效果进行更精确的测定。爆破的首要目的是生产出具有规定块度分布的破碎矿岩。目前,锡兴铁矿正在研究一种块度分布测量法。本文简要地介绍了这种方法,以期同各种块度分布测定法交流看法。只要能可靠地评价破碎岩石的块度分布,便可通过爆破试验得出有意义的结论。从而可使设备生产能力与爆堆性质联系起来,而且还带来一些其它优点。
With the increasing use of explosives in South African mines, a more accurate determination of the blasting effect is required. The primary purpose of blasting is to produce crushed ore with a defined degree of mass distribution. At present, Xi Xing Iron Mine is studying a block size distribution measurement method. This article presents a brief introduction to this approach, with a view to exchanging views with various lofty distribution assays. As long as the block size distribution of the broken rock can be reliably evaluated, a meaningful conclusion can be drawn from the blasting test. Thus linking equipment production capacity to the nature of the blast but with some other advantages.
