补充资料：矿区(床)平均品位
矿区(床)平均品位
average grade of deposit
kuangqu(ehuang)Pingjun Pinwei矿区(床)平均品位(average脚de of dePosit)整体衡量矿床贫富程度、确定矿床有无开发价值的一项指标。矿区(床)平均品位指标通常用价格法求出，计算原则是:在矿山服务年限内所获得的全部最终产品，其销售总收人与矿山服务年限内全部采、选、冶总成本加矿山基建投资及总利息之和正好相等时，所求出的品位值即为矿区(矿床)平均品位指标的取值下限。矿区(矿床)实际平均品位高于此值，表明如对矿山进行开发，可全部回收基建投资，并有利可图;否则基建投资将不能完全回收。(周家裹)
