摘要: 大冶铁矿尖山2#挂帮矿所在边坡垂直高度达300多m,整个矿体被与边坡走向几乎正交的F13大断层所横穿;经过几次开采后形成了大面积的采空区,这对2#挂帮矿的继续开采造成了极大的安全隐患。利用尾砂对空区进行充填处理,不仅可以有效地防止边坡下滑,保护国家地质公园景观,还可以为挂帮矿的继续回收创造条件。残矿的开采改用充填法进行,可最大限度地回收资源,并为露天转地下后充填法在矿山深部矿体开采中的全面应用积累了经验。

Abstract: The vertical height of slope in Jianshan 2# hanging wall ore of Daye Iron Mine reaches over 300 meters, and the whole ore body is traversed by F13 huge fault which is almost orthometric with the slope.Large mined-out area has been formed after exploiting for some times, leading to a great hazard to safety mining.Filling the mined-out area with tailings can not only prevent the slope failure and protect the national geological park landscape, but create conditions for continuous recovery of the hanging wall ore.The recovery of residual ores by the back-fill mining method can maximize the recovery of ores and accumulate experiences for the application of back-fill method in the deep mine after open pit transferring into underground mining.

Key words: Hanging wall ore, High and steep slope, Filling mined-out area, Recovery of residual ores
