摘要
采矿贫化率与损失率的降低是采矿工作者重点研究和攻克的难点之一。必须通过严格合理的采矿顺序，不断加强和提高采矿设计质量，强化施工管理等措施才能使其下降到理想水平。
The lowering of mining dilution ratio and loss ratio is one of major difficulties in front of mining researchers.In order to lower mining dilution ratio and loss ratio to an ideal level, some mesurements should be taken ,such as using a strict and rationable mining sequence,impoving the quality of mining design ,and enhancing construction management.
