摘要

The article studied the overlying strata structure and its movement evolution law of long wall paste filling coal face using similar material simulation. The result indicated that the movement of overlying strata in filling coal face was different from the regular coal face. The overlying strata structure in the filling coal face evolved mainly in the form of arch not in articulated beam. The overlying strata movement is developed from bottom to top in the form of separation layer, and the separation layer of upper rock is formed when the low rock layer closed.
