铜街、曼家寨矿床开采实践认识探讨

Discussion on mining practice of Tongjie and Manjiazhai deposits

铜街、曼家寨矿床是一个以锌、锡金属为主,伴生铜、银、铟、镉、铁、硫有益组分的超大型锡锌多金属矽卡岩型矿床(以下简称“铜曼矿床”)。矿山1958年建矿,发展到如今成为设备大型化、开采规模化、调度智能化及采选一体的矿山。随着矿产资源的开发利用,矿床开采深度不断加深,人们通过对矿床勘探资料和大量生产资料的综合分析研究,对矿床有了新的认识。本文将以探采资料为依据,重点论述矿床地质特征、控矿因素、勘查程度实践认识,旨在进一步全面、准确、客观地认识该矿床,为今后提升矿产资源利用率、生产勘探工程合理布置、寻找深部隐伏矿体提供基础依据。

Tongjie Manjiazhai deposit is a super large tin zinc polymetallic skarn type deposit,which is mainly composed of zinc and tin and associated with beneficial components of copper,silver,indium,cadmium,iron and sulfur.The mine was built in 1958,and has developed into a mine with large-scale equipment,large-scale mining,intelligent scheduling and mining and beneficiation.With the development and utilization of mineral resources,the mining depth of the deposit is deepening.People have a new understanding of the deposit through the comprehensive analysis of exploration data and a large number of production data.Based on the exploration and mining data,this paper focuses on the geological characteristics,ore controlling factors and exploration degree of the deposit,aiming to further understand the deposit comprehensively,accurately and objectively,and to provide the basis for improving the utilization rate of mineral resources,reasonable layout of production and exploration engineering,and searching for deep concealed ore bodies.
