摘　　要：为了研究厚松散层大采深地质条件下多工作面接续开采地表移动变形规律,以开滦钱家营矿十采区岩移观测站观测数据为基础,对多工作面接续开采后地表动态变形进行分析总结,拟合计算了不同开采宽度下地表移动变形预计参数和岩移角量参数,补充了该地质条件下地表移动变形特征。In order to study the laws of the surface movement and deformation of the continuous mining of the multiple working faces under the geological conditions of the thick loose layer and the large mining depth,based on the observation data of the rock movement observation station in No.10 mining area in Qianjiaying Mine in Kailuan,the surface dynamic deformations after the continuous mining of the multiple working faces were analyzed and summarized,and the predicted parameters of the surface movement and deformation and the rock movement angle parameters under different mining widths were fitted and calculated,the characteristics of the surface movement and deformation under the geological conditions were supplemented.
