摘要
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。
Based on measured dataof Dongpang Mine, Xingtai, and with the aidof simulationtest of equivalent material, the rules of ground movement caused by mining under thick alluvium are described. The method for measuring the effect of mining is put forward. The problems of greater subsidence factor and the active period of surface movement are expounded. The mechanism of displacement and failure in the thick alluvium and the rock is revealed. The relation between the rockmass movement and the alluvium subsidence is brought to light. The conclusions obtained from theoretical study and practical application are very valuable.
