Abstract: One pass cutting coal mining face of large mining height under the thick loose layer has features of high mining strength and high recovery rate.And，the surface subsidence deformation and rock movement parameters have its own characteristics 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 data，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 development，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.
