Measurement Analysis in “Three Rates”of Open Deposit in Indicators Influencing Factors

以中信大锰矿业有限责任公司下属矿山天等锰矿和大新锰矿露天开采为例,分析露天矿床"三率"指标计算过程中的影响因素,并提出相应的解决方案。健全地质、采矿、选矿过程中的技术、设备、工艺等条件,建立合理"三率"指标考核体系,是改善"三率"指标的主要措施。

This article takes Tiandeng and Daxin manganese mine as an example to make an analysis of strip mining in the process of “Three Rates”index calculation to propose the corresponding solution,lncluding sound process of geology,mining,mineral processing technology,equipment,process conditions,such as establishing reasonable“Three Rates”index evaluation system,all are main measures to improve the “Three Rates”indicators,we think.
