摘要
随着磷矿市场供求关系的变化,磷矿石销售价格大幅度上涨,矿山企业原来确定的露天境界可根据市场因素进行综合优化,为此重新计算了适合于瓮福磷矿英坪露天矿Ⅱ号坑采区的新的经济合理剥采比,以调整和优化露天开采最终境界。
with change of supply and demand in phosphate ore, phosphate ore price in home market has increased sharply. For the reason, the new economic reasonable stripping ratio applicable for Ⅱ mining area of Wengfu Yingping Open-pit Mine was determined to adjust and optimize final mining area of open-pit mine.
