摘　　要：充填开采条件下上覆岩层变形移动特征不同于全部垮落法,为了获得其上覆岩层变形移动特征的差异,以邢台矿7608充填开采工作面为试验背景,采用相似材料模拟工作面回采和充填过程,采用三维静态变形测量系统对上覆岩层进行了变形观测。通过对比充填率为90%和0时2种不同情况,获得了充填法和全部垮落法管理顶板条件下上覆岩层变形移动特征和充填对覆岩移动的影响规律。The movement features of overlying strata under the condition of filling mining are different from the entire roof subsidence, in order to obtain the difference of the deformation and movement characteristics of the overlying strata,taked No.7608 filling coal mining face of Xingtai mine as the trial background and the processes of faces mining and filling were simulated in laboratory by using similar material ,and the deformation of overlying strata is observed by using three dimensional static deformation measurement system. Simulation studies were carried out on the filling ratio of 90% and 0,then by combining field measured results the regularity of overlaying strata was revealed.
