个旧锡矿老厂矿田接触带矿床勘查工程布置合理性探讨

老厂矿田位于个旧东区中部,随着生产勘探向外围深部拓展,亟需开展勘查工程布置合理性研究,有效控制勘探风险,为矿山下一步找矿提供技术支撑。通过对已知矿体勘查工程间距和网度研究,再对不同中段和不同网度下矿体资料的对比分析,综合得出矿山下一步工作中的参考网度:深度大于300m,预查网度200×100m,深度200~300m,普查网度120×80m,深度100~200m,详查网度50×50m,深度0~100m,勘探网度25×50m。

Discussion on the Rationality of the Layout of the Exploration Project in the Contact Zone of Old Factory Ore Field in Gejiu Tin Mine

The old factory mine is located in the middle of the Gejiu East District.With the expansion of production and exploration to the outer periphery,it is urgent to carry out research on the rationality of the layout of the exploration project to effectively control the exploration risk and provide technical support for the mine's next prospecting.Through the study of the interval and network degree of the known ore body exploration project,and then the comparative analysis of the ore body data in different middle sections and different network degrees is conducted,and the reference network degree in the next work of the mine is comprehensively obtained:the depth is greater than 300m,the pre-inspection network degree is 200×100m,depth is 200~300m,survey network degree is 120×80m,depth is 100~200m,the detailed investigation network degree is 50×50m,depth is 0~100m,and the exploration network degree is 25×50m.
