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。
Research on rock strata and surface deformation is a comprehensive subject that involves many fields of expertise. There are many researches on overburden destruction and surface subsidence in China’s coal mines, while the deformation of the middle rock strata is still relatively few. In this paper, FLAC3D is used to simulate the deformation of rock strata and ground surface in the upper 3 and lower 3 coal mines respectively. The deformation of the ground surface and middle rock strata are analyzed by MATLAB software. By the error analysis, the deformation of the rock surface and the inner rock strata is determined Fitting function.
