摘　　要：针对未来黄金价格的走势做出预测,结合矿山实际情况,合理确定了矿产品的最终价格,基于黄金市场分析适当调整了矿体的工业指标,对地质储量进行了重新核算,提出了符合矿体开采技术条件的开发方案并对其进行了评价,结果表明,矿体开采条件较好,相关工艺技术成熟,现有系统可满足生产要求,投资内部收益率高出行业要求9.5个百分点,明显经济可行。Through prediction of the future price of gold and combination with the practical situation of mining,the final price of the ore products was determined. Based on the analysis of gold market,the industrial indexes of ore body was timely adjusted,and the geological reserves were re-accounted. Then,a new mining method,which was accordance with the mining technical conditions,was proposed and evaluated. The results showed that the mining conditions of the ore body were desirable,the related mining technology was mature,and the existing production system could meet the producing requirements. Moreover,the financial internal rate of return was higher than the industry regulation by 9. 5 percent point,with obvious economic benefits.
