摘要
山坡露天矿转入凹陷开采以后，将产生剥采比增大．新水平准备周期延长，开拓运输系统复杂等一系列问题。本文结合歪头山铁矿（主采场）转入凹陷开采后，生产能力下降的实际情况．分析了具体原因，并提出相应的解决措施。
After transtering to deep open-pit mining, a series of problems would be caused such as the strip-ping trtio is higer, the preparation periods of new levels are longer and the transport system for minedevelopment is complex. Combined with practices of Waitoushan lron Ore Mine (the main miningarea ) which had been transfered to deep open-pit operation and its capacity was decreased, this paperanalyses the concrete causes and suggestes the measures for their solving.
