摘要
目前我国大部分铁矿山面临由露天转入地下开采问题,而由露天转入地下开采会遇到许多新的技术问题,其中最主要的问题是如何实现平稳过渡和如何实现生产衔接。针对露天转地下开采的主要问题即平稳过渡措施问题,制定出了一系列平稳过渡的措施方案:分期建设、增加脉内措施井(巷)工程、回收残矿等,取得了理想的效果。
Presently, most of the iron mines in China have to face the issue of transition from open-pit mining to underground mining. Such transition will involve many technical issues and the most important one is how to realize a steady transition and the production convergence. In light of the main issue in the transition from open-pit mining to underground mining, a series of measures for a steady transition were planned, adopted and achieved ideal effect, including staged construction, increase of in-vein measure shaft(drift) engineering and recovery of residual ore.
