七里坪金矿生产实践中降低贫化率、损失率措施的探讨

矿产资源开发中的贫化损失是不可避免的,但可以通过一些技术、管理手段来降低贫化率与损失率,充分利用矿产资源,提高经济效益。七里坪金矿有着其独特的地质条件,通过分析金矿矿石贫化和损失的客观和主观原因,如地质资料的准确性,采矿工艺的合理性,工作人员的思想认识等,紧紧抓住矿石贫化率和损失率居高不下的关键因素,采取一系列措施,包括加强矿山地测工作,完善采矿设计,合理修正矿体可采厚度、夹石剔除厚度,改进采矿方法,加强采矿各工序间的配合,加强质量管理工作等,有效降低了矿石贫化率与损失率,进一步延长了矿山的服务年限,对矿山具有很重要的经济和技术意义。

Reduction Measures on Dilution and Loss Rate of Qiliping Gold Mine

The dilution and loss are inevitable in the development of mineral resources,but we could take some techniques and management measures to reduce the dilution and loss rates,maximize the recovery of mineral resources,and improve the economic performance.Qiliping Gold Mine has its unique geological conditions.With the analysis of internal and external reasons,such as the accuracy of geological data,the applicability of mining technology,etc.,we could take many measures,such as improving mine design and survey,adjusting minable thickness of ore bodies and maximum thickness of interlayer,improving mining method and the cooperation between the various processes,improving quality control,to effectively reduce the dilution and loss rates,and further extend the life of mine.It has significant economic and technical meaning.
