摘要
矿床工业指标是圈定工业矿体、估算工业矿产资源储量和评价矿床工业价值所遵循的标准。谦比希铜矿东南矿区是该矿资源量最大的矿床,目前正在进行开发建设。结合东南矿区详查和设计实践,采用多方案综合技术经济分析方法对矿床工业指标进行了研究,确定的工业指标已应用于矿山工程设计工作中。研究充分考虑了矿床工业指标动态变化的特点。随着对矿床成矿地质条件和矿床开采技术条件了解的深入以及市场和技术经济条件的变化,工业指标是变化的。
Industrial indexes of ore deposits are criteria for orebody delineation,ore resource estimation and economic evaluation,which partly reflect the level of scientific technology and industrial development.As the largest deposit in Chambishi copper mine,southeast orebody is under development at present.Combining with geological survey and practical design of this orebody,the deposit industry indexes were studied by means of multi-option analysis by calculating their comprehensive economic benefits.The defined indexes were adopted in the engineering design.Dynamic change of the indexes was considered comprehensively in the study.With the accumulation of in-depth knowledge about metallogenic mechanism and mining conditions,deposit industrial indexes would be changed to comply with updated market and technical-economic conditions.
