浅析大红山铁矿Ⅱ2-1矿体矿石类型及其分布特征

A brief analysis of ore type and distribution characteristics of Ⅱ2-1 orebody in Dahongshan iron mine

铁矿体圈连时仅依靠矿石单TFe品位对矿体进行圈连,易造成对矿体总体特征认识产生偏差。为摸清矿体矿石类型和分布特征,对后续采矿设计和选矿方法的选取提供更准确的指导。本文通过开展坑道地质编录工作,根据矿石主要金属矿物、脉石矿物、结构、构造等特征,进一步结合刻槽样及探矿钻孔样化验结果统计分析,查明了Ⅱ2-1矿体矿石类型及其分布特征。

When the iron ore body is linked together,it only depends on the single TFe grade of ore to link the ore body,which is easy to cause incomplete understanding of the overall characteristics of the ore body.Clearing orebody ore types and distribution characteristics of successive mining design and selection of beneficiation method has important guiding significance in this paper,through the tunnel geological record work,according to the main metal mineral,ore gangue mineral,structure,characteristics,etc,combined with groove and prospecting drilling test results of statistical analysis,the authors find out the Ⅱ2-1 ore type ore bodies and the characteristics.
