摘　　要：铝土矿作为我国工业领域关键的资源之一,在金属及非金属应用中占据着重要地位,并且是制造铝的最佳原料,其消耗量占据了整体消耗的绝大部分。基于此,本文首先探讨了铝土矿的分布状态以及其品位下降与资源损耗的情况;其次详细解析了在地下开采过程中导致铝土矿损耗和品位降低的主要因素;最后,提出了若干策略以减少在地下开采铝土矿过程中的损耗与品位降低,旨在为相关行业提供参考性建议。Bauxite,as one of the key resources in China's industrial field,occupies an important position in metal and non-metal applications,and is the best raw material for manufacturing aluminum,and its consumption accounts for the vast majority of the overall consumption.Based on this background,this paper first discusses the distribution of bauxite and its grade decline and resource loss.Then,the main factors leading to the loss and grade reduction of bauxite during underground mining are analyzed in detail.Finally,some strategies are put forward to reduce the loss and grade reduction in underground bauxite mining,aiming at providing reference suggestions for related industries.
