厚松散层薄基岩下开采引起的地表移动规律及地表移动参数，有其明显的自身特点和规律。

The regularity and parameter of surface movement aroused by mining under thick soil layer and thin base rock have its obvious characteristic and regularity.

以关键层理论、传递岩梁理论以及采场上覆岩层及地表移动规律理论为基础，推导出岩梁抗弯刚度的误差补偿公式。

On the basis of key rock strata theory, transferring rock beam structure and the law of the overlying strata displacement and the surface subsidence theory, we deduced offset error formula.

已有的岩层与地表移动规律基本上以岩石强度为基础，很少顾及岩体中裂隙弱面的存在，及其对岩层与地表移动规律的影响。

The laws on the rock strata and surface movement that have known is basically based on the rock strength, not considering exist and the effect on the subsidence laws of the fissure and the weak face.
