摘要
系统抽样摄影法是在铲、装矿岩过程中对爆堆进行抽样摄影,以获得平面块度分布,然后通过数学处理方法将它转换为爆堆的整体分布。为建立此法,文中提出了一整套试验方法并获得了试验结果。经与实测所得的大块率对比表明,摄影法是一种行之有效的方法。
During shovel loading process, systematic sampling photography are taken of blasted rock piles so as to estimate bivariate distribution of boulder size, then tridimensional distribution is obtained through mathematical treatment. In order to establish this approach, the testing methods and testing data are proposed. From this study, it shows that photography is effective to estimate boulder rate, as compared with the field measured result.
