某露天矿扩帮形成覆盖层方法探究

摘要

Based on the topography and geology condition and the occurrence state of slope ore of an open pit which comes to the end of strip mining,a method is put forward that the overburden layer is formed through the goaf backfill with slope expansion,and the way that the slope ore mined with adit caving method is researched.The ore production during the period of transforming is effectively supplied by the ore product through slope expansion and adit stoping,which provides guarantee for the stable transformation from open-pit to underground mining.%根据某矿山露天开采结束时的地质地形条件和边坡矿的赋存状态，提出了扩帮回填采空区形成覆盖层的方案，研究了平硐崩落法回采边坡矿的方法。扩帮和平硐回采生产的矿石有效补充过渡期内的矿石产量，为实现露天转地下平稳过渡提供了保障。
