摘　　要：矿体埋藏从浅部延伸至深部的资源,上部常采用露天开采方式,但随着浅部资源的逐渐耗竭,深部转向地下开采成为了必然趋势。在露天转地下开采过程中,存在一些挑战,其中之一就是如何优化隔离矿柱的设计,以确保上、下部开采安全、露天与地下开采的接续性和最大程度地提高资源回收率。本文旨在研究露天转地下开采中,隔离矿柱优化方法和技术,为类似矿山安全、平稳实现露天转地下生产提供参考。Mineral resources extends from shallow to deep,open-pit mining is often used in the upper part.However,with the gradual depletion of shallow resources,the shift from deep to underground mining has become an inevitable trend.In the process of converting open-pit to underground mining,there are some challenges,one of which is how to optimize the design of isolation pillars to ensure the safety of upper and lower mining,the continuity between open-pit and underground mining,and the maximum improvement of resource recovery rate.This article aims to study the optimization methods and techniques for isolation pillars in open-pit to underground mining,providing reference for the safe and stable implementation of open-pit to underground mining in similar mines.
