摘　　要：根据实测数据工作面地表移动延续时间、起动距、最大下沉速度滞后角等动态参数,研究赵楼煤矿巨厚表土层开采地表移动变形规律。研究表明,赵楼煤矿工作面最大下沉速度随着采厚和采宽采深比的增加而增大,最大下沉速度滞后角随着工作面推进速度和采深的增加而增大,拐点偏移距随着表土层厚度的增大而减小。According to the dynamic parameters such as the duration of surface movement,starting distance and lag angle of maximum subsidence velocity in the measured data,the law of surface movement and deformation in super-thick topsoil mining in Zhaolou Coal Mine is studied.The study shows that the maximum subsidence velocity of the working face in Zhaolou Coal Mine increases with the increase of the mining thickness and mining width-depth ratio of the working face,and the lag angle of the maximum subsidence velocity increases with the increase of the advancing speed and mining depth of the working face.The inflection point offset decreases with the increase of the thickness of the topsoil layer.
