mining sequence of level
{一eduon伙。!eol shunxu阶段开采顺序(mLning、equenee of level)同井田内各阶段的开采次序。阶段开采顺序分下行式和上行式两种。下行式是先采上阶段，由上往下逐阶段回采。上行式则相反。下行式开采的主要优点有:(1)初期开拓所需时间短，基建工程量和投资小。因为不需要把井筒一次掘进到整个矿体的深度;如果用下盘竖井开拓，上部阶段的石门比下部阶段的石门短(2)初期开采的是矿体浅部，一般为高级储量，可以避免因勘探不足而造成开拓工程的浪费;此外，在生产的同时可以进行矿床深部勘探(3)可以适应任何采矿方法上行式开采在许多采矿方法中是不能采用或难以采用的;一般只能在开采下富上贫;或者上部是氧化矿或难选矿石，下部是原生矿或易选矿石;或者矿体上小下大，用下行式开采难以达到建设规模等条件下的缓倾斜矿体中采用。 (李鼎权曾耀)
