| 摘 要： | 具备一定条件的露天矿，可以在设计的最终境界内人为地用临时非工作帮划分出若干个分期临时境界，逐期顺序开采和扩帮过渡，过渡期一般以10～15年为宜，每一期的工艺参数要为下一期和而后各分期的采剥工程发展服务，使之密切衔接。

| Abstract: | The open-pit with specified conditions can be divided in final boundary with some stage boundaries, and the mining and wall pushback can be carried on by stages in sequence. The transi-tion stage is of lO- l5 years usually. The technical parameters of every stage are necessary to serve the mining and stripping the next stages for colse dovetail between them. |
