本文叙述一种预测原岩矿石块度(矿石崩落,产生破碎作用之前的块度)的方法.通过实例说明节理的重要特性(抗剪强度,持续性及间距)的影响。定性预测结果表明,与已发表的矿石块度组成是一致的.计算出的矿石块度组成与实测的矿石块度组成间的关系还有待于进一步研究.
In this paper, a method of predicting the lumpiness of raw rock ore (the size of the ore before rockfall and the crushing effect) is described. The effects of the important characteristics of joint (shear strength, continuity and spacing) are illustrated by examples. Qualitative prediction results show that it is consistent with the published ore block composition.The relationship between the calculated ore block composition and the measured ore block composition remains to be further studied.
