摘要：
Overburden rock of mine space was regarded as huge system of complex medium. According to the different mechanic characteristic of the upper rock and the lower rock, the layer-discrete duality medium model was established. By the analysis method for thin plate layer medium combined with the discrete element simulation, the complex medium coupling effect of the layer-discrete duality medium were studied systematically, the movement and distribution laws of separated strata for the overburden rock were revealed.
