摘　　要：竖井作为矿山深部采矿的咽喉工程,其建设工期制约着整个矿山建设期,其服役期安全稳定是矿山正常安全生产的保障。本文以三山岛金矿副井工程为背景,研究探讨直径10.5 m、埋深1 915 m的大直径深埋竖井支护理念、支护方案及建设创新。通过深入研究国内外支护理论,突破传统设计理念,采用新型工艺卸压与充分利用围岩作用的设计理念,提出了大埋深竖井分区分序支护方案,探讨了深井建设的创新方向。文章研究成果能够为深地开发利用的瓶颈工程支护设计提供参考应用,为储备2 500 m以浅的深井建设技术及相关深井工程提供重要借鉴。As the throat project of deep mining in the mine,the construction period of the shaft controls the whole mine construction period,and the safety and stability of its service period restricts the normal safety production of the mine.Based on the auxiliary shaft project of Sanshandao gold mine,this paper studies and discusses the support concept,support scheme and construction innovation of large-diameter deep-buried shaft with diameter of 10.5 m and buried depth of 1915 m.Through in-depth study of domestic and foreign support theory,breaking through the traditional design concept,adopting the design concept of new process pressure relief and making full use of the role of surrounding rock,this paper studies the support scheme of large buried deep shaft,and discusses the innovation direction of deep well construction.The research results of this paper can provide reference application for the support design of bottleneck engineering in deep development and utilization,and provide important reference for the construction technology of deep well and related deep well engineering below 2500 m.
