呷村银多金属矿小体重测试成果报告

Report on small weight test results of GACUN Silver Polymetallic Mine

呷村银多金属矿自出具1993年版的勘探报告以来,一直未进行过系统的矿石体重实验。随着矿山开采深度的增加,矿石矿化类型、矿化均匀程度变化增大,矿山一直沿用银铜铅锌矿石和独立铅锌矿石的平均体重值(银铜矿石3.4t/m^(3),独立铅锌矿石3.21t/m^(3))进行生产计算,对矿山储量、采场采出矿、贫化损失管理均造成一定负面影响,不再符合矿山现场实际以及公司精细化管理要求,因此急需开展新的矿石体重实验。

Since the 1993 version of the exploration report of the Gacun Silver Polymetallic Mine was issued,no systematic ore weight experiment has been carried out.With the increase of mining depth,the change of ore mineralization type and degree of mineralization increased.The average weight value of silver-copper-lead-zinc ore and independent lead-zinc ore(silver-copper ore 3.4t/m^(3),independent lead)has been used in mines.Zinc ore 3.21t/m^(3))for production calculation,which has a certain negative impact on mine reserves,stope mining and dilution loss management.It no longer meets the actual mine site and the company’s refined management requirements,so it is urgent to develop new ore Weight experiment.
