| 摘 要： | 简述了FLAC3D数值模拟的基本原理、特点和应用于分析采矿工程岩体受采动影响发生破坏稳定情况的优势。用FLAC3D软件建立了某煤矿不同采宽条带开采的模型,得到了稳定后剖面位移场图。根据数据,描绘了条带开采地表移动曲线并进行了分析。从而确定了地表变形在Ⅰ级破坏范围内的合理采留宽度,为研究条带开采地表移动规律和“三下”压煤条带开采设计提供了依据。

| Abstract: | The basic theory,characteristics of FLAC~(3D) numerical simulation and its advantage of being applied in the analysis of engineering rock strata influenced by mining are simply shown in this paper.Different mining width models in a colliery were set up with FLAC~(3D) software and the figures of section displacement field after stabilization were gotten.Based on data,surface movement curves of strip mining were drawn and analyzed.Thus, rational mining and pillar width were confirmed to ensure that surface distortion is within Ⅰ degree damage and some foundations were provided for the research of movement rules of strip mining and the design of strip mining. |
