It is first raised that safety coefficient can be calculated by using the widths of yield zone and pillar, and the steps of designing the strip mining size are pro-posed.

首次提出了根据屈服带宽度和条带煤柱宽度来确定条带开采安全系数的方法，同时给出了设计条带开采尺寸的步聚。

The lag distance of abutment pressure behind working face increases, but the convergence coefficient of vertical stress doesn't change obviously with the increase of mining height.

分层开采与综放开采工作面滞后支承压力变化规律是，随着采高的增大，工作面滞后支承力的距离加大，垂直应力集中系数差别不大。
