The results show that distinct " bench " distribution rule takes on for the subsidence and distortion of bench - shape slope surface ; the movement range of bench - shape slope surface is smaller but its distortion is larger than those of flat surface and concentrated distortion occurs at every bench plan ; the surface horizontal distortion of bench - shape slope is still pressed in gob centre and tensioned in both sides of gob ; space - time effect should be taken into account for the stability of bench - shape slope influenced by underground mining
結果表明：露天煤礦臺階狀邊坡體的采動沉陷規律表現出很明顯的「臺階」分佈特點；臺階狀邊坡地表的移動范圍比平地地表要小，但變形卻更劇烈，且在各臺階平面處形成變形集中；臺階狀邊坡地表的水平變形仍然呈現出采空區中間受壓，兩端受拉的特點；臺階狀邊坡在地下開采擾動下的穩定性應考慮采空區的時空效應。 -
