关于缓倾斜厚大矿体采矿方法的探讨

On the Mining Method of Slowly Inclined Large and Thick Ore Body

以新桥硫铁矿Ⅰ #矿体西翼缓倾斜厚大矿体的开采为实例 ,对生产中应用的水平分层充填采矿法和分段空场嗣后一次充填采矿法进行分析比较 ,提出采矿方法的优化建议 。

With the mining of No.1 Ore body which is solwly inclined,large and thick at the west flank of xinqiao pyrite Mine as the example,analytic comparision is made between flat-back cut and fill stoping and sublevel open stoping with one-time delayed filling.The suggestion on the optimization of the mining and the discussion on appropraite mining method and the technical parameters of mining technology for slowly inclined large and thick ore body are also made.
