以邢台矿区东庞矿实测资料为基础，辅以室内相似材料模拟实验研究，介绍了巨厚松散层下采煤引起的地表移动特征，提出了采动程度衡量方法，阐述了地表下沉系数偏大和地表移动剧烈活跃期等问题，揭示了厚松散层和岩层内部移动破坏机理，以及岩体移动破坏与地表沉陷的关系，得到了一些在理论研究和实际应用等方面都很有价值的结论 Based on the measured data of Dongpang mine in Xingtai mining area, supplemented by simulation experiments of similar materials in the interior, the characteristics of surface movement caused by coal mining under thick and loose layers are introduced, and the measures of mining extent are proposed. The surface subsidence coefficient And the intense active period of the earth’s surface movement, revealing the mechanism of internal mobile failure of the thick loose layers and rock strata, and the relationship between the movement and destruction of the rock mass and the surface subsidence. Some valuable conclusions have been obtained both theoretically and practically
