矿石

The transmission depth of superimposed stress on foundation due to stocking large-area mineral ore is especially deep and slowly converges, when mineral ore stockyard is in operation, it will arise large superimposed stress on stockyard foundation and even deep foundation.

矿石堆场大面积的堆矿荷载产生的地基附加应力传递深度大、收敛慢，在矿石堆场投入使用时，堆场地基、甚至深层地基都将产生很大的附加应力。

N\nWhere the Romans recognized metal ores on the surface, they could follow them into the ground by strip-mining the surface ("the debris of undermined mountains"), or digging short tunnels.

n\n当罗马人在地表发现金属矿石，他们会挖开地表，深入土层来追寻这些矿石，或者挖掘一个短的地道。

On the basis of 2005 Iron Ore Mineral Resouces Database of China,this paper has summarized the general structural char-acteristics of all iron resources identified to date in China,such as deposit type,ore type,ore quality,mineral combination,exploration level and burial depth.

以中国2005年的铁储量库为基础，总结了中国铁矿查明资源的矿床类型、矿石类型、矿石品级、矿产组合、勘查程度、矿体埋深等的结构特征。

ABSTRACT Sublevel caving method is a high efficiency mining method for underground mine, it has many advantages, such as a simple mine stope, good work condition, high mechanization and low mining cost. Up to now, this method has been used in more than 85 percent of all underground iron mine.

无底柱分段崩落法是一种高效率的采矿方法，具有采场结构简单，作业条件好，机械化程度高，回采强度大，采矿成本低等优点，迄今应用该采矿方法采出的矿石量约占我国地下铁矿采出矿石总量的85％。

After study of the relatuons of the structure,texture and associated minerals a great number of natural gold and telluride are discovered in the ore.

根据对拉拉铜矿床的矿石结构、构造及矿物共生组合的研究，发现矿石中含有大量自然金和含铂族元素的碲化物。

When the ancients couldn't judge content of gold in rocks with naked eyes, they beat ores into mash in stone mortar, put them into trencher, panned them in water, and discarded coarse materials.

当古人用肉眼无法鉴定矿石中金的含量多少时，则将矿石在石臼中捣碎，装入木

When the breaker works, the electric motor revolves passes the blet pulley or the shaft coupling, the drive shaft and the cricular cone department in the heart set comples moves cricles one fixedly does turnd on lathe suspends the movement, thus enable the cricular cone the wall to approach from time to time Leavel the solid attire to put on in the adjustment rolls over the white wall surface, causes the ore to be under the impact unceasingly in the cavity, the extrusion sum the curving functing but realize ore.

破碎机工作时，电动机的旋转通过皮带轮或联轴器、传动轴和圆锥部在偏心套的迫动下绕一固定作旋摆运动，从而使破碎圆锥的破碎壁时而靠近又时而离开固装在调整套上是轧白壁表面，使矿石在破碎腔内不断受到冲击，挤压和弯曲作用而实现矿石的破碎。

Six kinds of minerals, such as pyrites, arsenopyrite, sphalerite, galena and cassiterite from various metallogenic stages, ore blocks and ore type s were analyzed by EMPA.

文章总结和划分了矿床的矿石类型、矿化阶段及其在空间上的分布；对不同阶段、不同地段和不同类型的黄铁矿类、毒砂、黄铜矿、闪锌矿、方铅矿和锡石等 6种主要矿石矿物进行了电子探针微区分析。

The gold ore types are mainly cataclastic and altered rock type.

红土沟-川刺沟金矿是一种典型的造山带中的韧性剪切带型金矿床，其主要的矿石类型为构造破碎蚀变岩型金矿石。

The deep origin of Kangjinla podiform chromitite is suggested by: that for the Kangjinla chromitite and the mantle peridotite rocks, the compositions of the chrome spinel, olivine and clinopyroxene are rather different, which indicates that the chrome spinel in the chromitite is neither the simple concentration of that in the host rocks nor with certain genic relation with mantle peridotite. Though the chromitite might be exotic for host rocks, both of them were carried from deep mantle to the shallow place by mantle plum.

康金拉铬铁矿石与矿体围岩地幔橄榄岩的铬尖晶石、橄榄石和单斜辉石等成分方面明显不同，认为矿石铬尖晶石并非是由副矿物铬尖晶石富集而成，与地幔橄榄岩也不存在成因联系，认为豆荚状铬铁矿床对于近矿围岩地幔橄榄岩而言为外来体，但两者可能均是由地幔深部被地幔柱带到上部。
