龙首矿东采区开拓工程探矿研究与实践

Research and Practice of Prospecting for Development Project at Eastern Mining Areas ofLongshou Mine

龙首矿东采区位于断层构造发育活动区,以往地质资料表明,此区域具有很好的探矿前景。在总结以往地质工作的基础上,通过构造解析及动力学分析,揭示了后期构造错动过程和晚期岩浆活动规律,确定了矿体的就位规律,构建了4种“就矿找矿”模型。同时,将地质技术工作延续到生产建设的全流程,在龙首矿东采区开拓工程实施了探矿工作,在主矿体上下盘发现了新的分枝富矿体,有效指导了后续探矿工作的高效开展。

The eastern mining area of Longshou Mine is located in the active area of fault structure development.Previous geological data show that this area has good prospecting prospects.On the basis of summarizing the previous geological work,through structural analysis and dynamic analysis,the late tectonic dislocation process and late magmatic activity law are revealed.The location law of the ore body is determined,and four“ore prospecting”models are constructed.At the same time,the geological and technical work extended to the whole process of production and construction,and the exploration work is carried out in the development project of the eastern mining area of Longshou Mine.New branch rich ore bodies are found in the upper and lower plates of the main ore body,which effectively guides the efficient development of the subsequent exploration work.
