【摘要】 在简明阐述矿区地质概况的基础上,对云西矿床富矿包的空间赋存、形态、矿物组合、矿化特征和控矿构造特点等方面进行了论述,并对富矿包的形成机制进行分析.结合矿山多年来的生产勘探和开采实践,尤其是云西矿床220中段富矿包的发现及其评价利用,总结出云西矿床富矿包呈台阶式分布、受脆性裂隙控制、与硅化岩密切相关、黄铜-黄铁矿硅化岩类型的矿石是富矿石类型等诸多规律,并以此规律为依据,对矿床深部富矿包进行了预测,指出深部有3个较大的富矿包台阶存在.

【Abstract】 Based on the brief explanation of the general geological situation, the article expounds the bonanzas occurence, shape, mineral assemblage, mineral nation characteristic, structural control and so on in Yunxi ore deposits. And formative macharism of bonanzas is also analyzed the principuim. After the experience of the long-term production exploration and exploitation, especially through the judgment of the bonanzas of 220 level in Yunxi mine, it has summarized that they are ladder-like distribution and controlled by brittle fractures, and that there is close bearing between silicified rocks and them. The ore is rich, which is chalcopyritized and pyrited one. According to the above, it is forecasted that there are three bonanzas which are ladder-like in the deep.
