厚松散层下大采高一次采全高工作面开采强度大，回采率高，地表沉陷变形和岩移参数有其自身特点和规律。为研究大采高工作面地表移动变形规律，在王庄煤矿8101工作面上方设置了地表移动观测站。通过对观测资料的分析研究，揭示了厚黄土覆盖区、厚煤层一次采全高条件下地表沉陷变形特征，获得了该地质采矿条件下地表岩移预计参数和各种角值参数，分析了地表裂缝的发育、分布特征、裂缝宽度和深度等规律。与综放开采条件下的观测成果相比，大采高一次采全高工作面地表移动变形更加剧烈，沉陷过程在空间上和时间上更加集中，对地面建构筑物的影响更为显著。

One pass cutting coal mining face of large mining height under the thick loose layer has features of high min-ing strength and high recovery rate. And,the surface subsidence deformation and rock movement parameters have its own char-acteristics and rules. To study the surface movement and deformation rule of working face with large mining height, surface movement observation station is arranged above the 8101 working face in Wangzhuang Coal Mine. By analyzing the survey da-ta,the characteristics of ground surface deformation and movement under the conditions of thick loess-covered and one pass cutting coal mining are revealed,different kinds of prediction parameters and angle parameters are obtained,and the rule of de-velopment,distribution features,crack width and depth of ground fissures are analyzed. Compared with the observation results in the conventional fully-mechanized caving face,the surface movement and deformation at the one pass cutting coal mining face is more severe,and subsidence processes are more concentrated in both space and time. The influence on building structures is more significant.
