金山店铁矿采场溜井维护措施与新建溜井设计要点

Maintenance Measures of Stope Chutes and Key Points of New Chutes Design in Jinshandian Iron Mine

以金山店铁矿为背景,对东区上、下盘采场溜井破坏现状及破坏原因进行分析研究。为减少今后溜井破坏情况,对于现已启用的溜井,在启用分层的溜井口加装格筛,并对使用完毕的井筒进行分段封闭;对于新建溜井,研究确定了溜井间距、位置、断面形状和尺寸。这些措施在金山店铁矿的实际生产中逐步应用,取得了积极的效果,对同类地下金属矿山溜井维护具有一定的参考价值。

Taking Jinshandian Iron Mine as the background,this paper analyzes and studies the cur⁃rent situation and causes of the destruction of the ore chutes in the upper and lower stopes of the east area.In order to reduce the destruction of the ore chutes in the future,for the ore chute that has been put into use,the screens are installed at the ore chute that has been put into use for layering,and the used shaft is closed in sections.For the newly-built chutes,the distance,position,section shape and size of the chutes are determined.These measures have been gradually applied in the actual production of Jinshandian Iron Mine,and have achieved positive results,which has certain reference value for the maintenance of chutes in similar underground metal mines.
