摘要
根据不贫化放矿理论，结合生产矿山条件，提出了生产矿山施行不贫化放矿的具体方法，主要有矿石数量过渡与质量过渡方法、改变截止品位的确定方法和若干分段组合放矿的方法．
Based on the theory of ore-drawing without dilution, and connected with the practical condition in mine,the concrete method used for ore-drawing without dilution in mine is put forward,which are ore quantity transition and quality transition method, method of changing determination of cut-off grade,and method of ore-deawing in certain sublevel composition.
