摘　　要：为实现煤矿采空区地表沉陷可视化,结合MATLAB仿真技术,利用矿区地质煤层条件和岩移观测参数及地表沉陷有关数据,建立采空区地表沉陷以动态时间函数结合概率积分法的预计模型,对煤矿开采造成的地面沉陷区进行仿真计算和分析.结果表明:该方法能反映地表移动的动态特征,实现了煤炭开采对地面动态沉陷影响的较为精确的分析与计算,可以直观而精确地对地表变形各种图形自动绘制,为其它矿区制定采煤采空区的预防和治理方案提供一个交互的三维仿真平台及可靠依据.Using MATLAB simulation technology, this paper has developed a prediction model on goaf surface subsidence with the integration of dynamic time function and probability integral method based on coal seam geological conditions, rock movement observation paramefers and surface subsidence data. It simulates and analyzes the surface subsidence caused by coal mining operations, and achieves the surface subsidence visualization. The results show the method can reflect the dynamic characteristics of surface movement. The system realizes the accurate analysis and calculation on the surface dynamic subsidence caused by coal mining, and can draw intuitively and precisely the graphics of surface deformation. It provides an interactive 3d simulation platform for formulating a prevention and control plan for surface subsidence at goaf area in a coal mine.
