对矿床进行开采的先后次序。一般是先主后次，先上后下，即先采主矿体上部，后采次要矿体和主矿体下部。在同一矿区内，若划分为几个井田，则其开采顺序有：几个井田同时开采、依次开采、同时和依次结合开采三种。同一井田各阶段的开采顺序，一般是自上而下，亦可几个阶段同时开采。同一阶段各采区沿走向的开采顺序，有前进式、后退式和联合式三种。在同一采区内的开采顺序则取决于采矿方法，空场法、留矿法、充填法一般由下而上开采；崩落法是由上而下开采。
最后得出关于采区合理走向长度和两种分层开采顺序适用条件的结论。
Finally, we concluded the optimal length of mining section along the strike and the appropriate conditions of application of these two sequences of mining slices.
对阶段中盘区回采顺序进行优化，得出“隔二采一”的最佳开采顺序。
By optimizing the sequence of panel mining stope of ore block, the mining sequence of the "two stope panels" is applied for the mine.
