随着国民经济的发展和科学技术的进步,露天采矿先后出现了全境界、分期、边采边扩和综合开采四种开采方式。分期开采克服了全境界开采生产剥采比大、基建周期长、投资大和投产达产时间长的缺点;边采边扩开采是从分期开采演变发展来的,它克服了分期开采在过渡时期剥离洪峰高的缺点,妥善地解决了分期开采扩帮过渡的一些复杂问题,是采矿科学技术发展的必然趋势。
With the development of the national economy and the advancement of science and technology, open pit mining has successively emerged in four modes of mining: entire territory, staging, edge mining and comprehensive mining. Staged mining overcoming the shortcomings of large-scale exploitation and production of the whole territory of mining and production, long cycle of infrastructure, large investment and put into production for a long time shortcomings; edge mining expansion mining from staged evolution evolved to overcome the phased mining in the transitional period of the divestiture The shortcomings of high peak, properly solve the phased mining expansion to help the complex transition of some of the transition is the inevitable trend of mining science and technology development.
