摘要: 大冶铁矿露天采场挂帮矿是该矿山露天转地下项目的重要工程,采用浅孔留矿法进行开采。在挂帮矿的开拓、回采过程中,考虑F9断层的影响,对采场布置技术进行分析。通过挂帮矿开采过程中对滑体的扰动进行分析,表明在采动过程中要特别注意形成空区的高度和暴露面积以及空区之间的矿柱尺寸,确保边坡及滑体的整体安全稳定性。

Abstract: The hanging wall ore of the open-pit is one of important projects in transition from open pit to underground in Daye iron mine,and the shallow hole shrinkage mining method is adopted in the project.In this paper,to consider the impact of fault F9,the stope layout techniques are analyzed in the process of development and mining of hanging wall ore.By the analysis of disturbance of landslide due to the mining of hanging wall ore,the height of the empty area and the size of the exposed area and the pillar between empty area should be focused specially in the mining process to ensure the security and stability of the slope and landslide.
