鉴于现行的建设项目经济政策,国家黄金管理局在《金矿工业指标制定细则》的总则中明确规定“……制定工业指标时,应考虑工业指标具有偿还投资的能力,保证矿体开采的经济效益”。因此,在确定矿区最低工业品位时,必须要考虑矿床开采中建设项目在一定期限内要实现贷款偿清和投资返本。 对此,目前存在着多种计算方法,本文就此问题探索了一条解决的途径,与读者商讨。
In view of the current economic policies of construction projects, the State Administration of Gold in the “General Rules for the Development of the Indicators of Gold Mines” stipulates clearly that “... when formulating industrial targets, consideration should be given to the ability of industrial indicators to repay investment and ensure the economy of ore body mining benefit”. Therefore, when determining the lowest industrial grade in the mining area, it is necessary to consider that the construction projects in the mining of the deposit should pay off the loan and return the investment within a certain period of time. In this regard, there are a variety of calculation methods, this paper explores a solution to this problem, discuss with the reader.
