摘 要:缓倾斜薄矿体的回采一直是采矿方法设计上的难点,国内外尚无很好的采矿方法可供参考。文章介绍了伪倾斜单采尾砂胶结充填采矿法在山东黄金集团三山岛金矿平里店矿区的实际应用情况。实践表明该方法应用于缓倾斜薄矿体,能很好地解决全面采矿法顶板支护、采空区塌陷和矿石搬运困难等问题,降低了损失、贫化率,取得了良好的经济效益。伪倾斜单采尾砂胶结充填采矿法对于类似缓倾斜薄矿体的开采具有一定的借鉴意义。The mining method of gently inclined thin orebody is difficulty for mining design and there is no good solution in our country up to now. An application of pseudo inclined single mining tailings cemented filling mining method is introduced in Pinglidian mining area, Sanshandao Gold Mine, Shandong Gold Group. It is shown that this method applied in gently inclined thin orebody can solve the difficulties of roof support, subsidence of stope and sur- face and ore transport met in the overall mining method, which also reduces the loss rate of dilution and gets good economic benefit. Moreover, this method supplies a reference in the excavation of other gently inclined thin ore- body.
