摘　　要：由于缺乏对本矿地质力学规律的研究,“三下”采煤及征迁赔偿等工作受到很大制约。因此掌握本矿区综采放顶煤开采条件下的地表移动和变形规律,具有重要研究价值。通过对王庄煤矿4326工作面地表移动观测站观测数据的地质力学分析,得出王庄煤矿放顶煤条件下的地表移动规律,取得了放顶煤开采的地表移动计算参数,为本区域“三下”采煤优化设计提供理论依据。Because lacks of the geodynamics research in mines, “three under” mining coal and moves work＇s compensation receives restriction. Therefore grasps the rule of the surface migration and the distortion under the caving the roof in full mining terrain has most important values. This paper through the geodynamics analyse of 4326 working face in Wangzhuang coal mine obtained the surface shift rule of the caving roof coal, get the parameter of mining caving roof coal, and provided a technologic basis for optimal design.
