| 摘 要： | 岩层与地表变形研究是一个综合性的课题,涉及多个领域的专业知识。我国煤矿对覆岩破坏与地表沉降进行研究的很多,而对中间岩层的变形进行分析的还比较少。本文运用FLAC3D分别对3上、3下煤开采岩层与地表变形情况进行模拟计算,并用MATLAB软件对地表与中间岩层的变形规律进行分析,经误差分析,最终确定了地表与内部岩层变形的最佳拟合函数。

| Abstract: | Deformation research on rock and surface is a comprehensive issue,involving multiple areas’ expertise.There are many researchers on surface subsidence and overburden failurey in China,but seldom research on the middle stratas’ deformation.This paper used FLAC3D to simulate the rock and surface deformation of mined 3upper and 3down mine respectively,used MATLAB to make fitting and regression about the deformation data,and studied the deformation regulation of the surface and internal rock.After the error analysis,it finally determined the best fitting function for the deformation of surface and internal rock. |
