摘　　要：露天矿采剥关系不仅仅是剥采比的数量关系,而更重要的是采剥工程发展的时空关系。要使矿山生产能持续而均衡地发展,必须在宏观控制的基础上,实施微观控制。在日常生产中要经常分析各项技术指标的变化规律,及时发现问题,积极进行调整,使露天矿各个部位都能协调地发展,避免露天矿采剥关系的失调。此外,作者从露天矿生产发展规律的共性,提出衡量露天矿采剥关系正常与否的4条准则,即合适的生产剥采比、协调的部位推进、充足合格的工作线以及足够的产量稳定储备能力。这是作者实践经验的总结,对指导露天矿生产有重要的意义。The relation between stripping and mining is not only a figure of stripping ratio. In fact, the relation of time and space of mining and stripping operations is more important. To ensure constant and balanced development of production, it is necessary to make microscopic control on the basis of macroscopic control. In routine production, changes of all technical parameters should be always checked, so as to find out problems in time. And positive adjustments can be made to achieve coordinated development of production in all the places in the surface mine, and to avoid imbalance between mining and stripping. Based on the general characters of surface mining, criteria for judging the relation between mining and stripping are proposed by the author. They are proper stripping ratio, coordinated advance of faces, sufficient and qualified working lines, and enough and stable coal reserves. These are author's experience obtained in practice, which are important guidelins for surface mines.
