摘要: 为明确中关铁矿深部矿体开采后地表移动区内建(构)筑物的安全性,尝试利用大型通用有限元分析软件ANSYS对胶结充填体作用下地表的开采沉陷规律进行了模拟,结果表明,厚矿体移动区外,薄矿体移动区内的建(构)筑物是安全的;初步揭示了全尾砂(胶结)充填后地表的沉陷规律,指出充填体能有效控制覆岩的变形,地表的变形很微弱,未出现明显的移动盆地。

关键词: 稳定性, 胶结充填, 沉陷规律, 模拟分析

Abstract: To make sure about the safety of the buildings and structures in the surface displacing area after the deep mining at Zhongguan Iron Mine, attempt was made to use large universal finite element method-ANALYSIS to simulate the law of mining-caused surface subsidence when cementation filling was adopted.The results show that the buildings and structures in the area outside the thick orebody moving area but within the thin orebody moving area are safe, preliminarily reveal the ground subsidence law after a total tailing (cementation) filling, and indicate that the filling body can effectively control the deformation of the overlying rock, with the ground surface deformation being very weak and with no evident displacing basin formed.

Key words: Stability, Cementation filling, Subsidence law, Simulation analysis
