| 摘 要： | Morrito铁矿严格受断裂构造控制,在空间上的厚度、品位有较大变化。利用统计学的方法,研究了矿脉厚度、品位的变化系数,对矿体的资源/储量估算及开采都有重要意义。对矿体厚度及品位变化系数的分析认为,矿体形态变化程度属"简单";矿体有用组分分布属"均匀";矿体倾向变化大于走向变化,并表现为不明显的方向性变化。

| Abstract: | Morrito iron mine was strictly controlled by faults. The thickness in space and grade varied greatly. The authors used statis- tical method to study the veins thickness and grade of the coefficient of variation, which were important for the ore reserve estimatation and mining. On the ore body thickness and grade variation coefficient analysis, the authors considered that the morphological changes of the ore body was ＂simple＂ ; useful components of the ore body distribution was ＂uniform＂ ; tendency of the ore body was greater than that of strike variation, and showed a less obvious directionality. |
