关于浏阳磷矿陡帮开采的工艺特征和经济效果,国内不少同志均作了比较详尽的阐述。本文除了对浏阳磷矿采用陡帮开采前期的经济效果作出估价外,还将尝试采用企业经济评价方法对该矿整个服务期间的经济效果作一个定量的评价,以期大家有个更清晰的印象,算作拙文“浏阳磷矿陡帮开采的工艺特征”(载于《有色金属》[矿山部份]1985年第3期上)的续篇或补充。
About Liuyang phosphorite steep mining process characteristics and economic effects, many domestic comrades have made a more detailed exposition. In addition to appraising the economic effect of steep rock mining in Liuyang Phosphate Mine, this paper will also try to use the method of enterprise economic evaluation to make a quantitative evaluation of the economic effect of the mine during the entire service period so as to have a clearer picture, Count as a clumsy “Liuyang phosphate rock steep mining process characteristics” (contained in “non-ferrous metals” [Mining] No. 3, 1985) sequel or supplement.
