MSDFVS系统在开采沉陷预测中的应用

The Application of MSDFVS System in Mining Subsidence Prediction

为准确预计煤矿回采工作面的开采沉陷值,合理布置采区,减小由地下煤炭开采引起的地表移动破坏,对基于MapInfo的MSDFVS(矿区地表变形预测预计与可视化系统)在预计原理、预计模型编程、算法方面做了详细介绍。通过实例验证了该系统的正确性及合理性,结果表明,该系统不仅实现了单个工作面、多个工作面的静态和动态沉陷预计,还实现了预计结果的二维、三维以及动态可视化,其预计结果更是在地表沉陷预测及控制、"三下"采煤等方面具有一定的指导意义。

To accurately predict the mining subsidence value of the coal mining working face, rational arrangement of the mining area, reducing the damage of ground movement caused by underground coal mining, predicting principle, predicting model programming and algorithm of MSDFVS （ mining area ground surface deformation forecast and visualization system） based on MapInfo has been intro- duced in detail. The correctness and rationality of the system is verified by an example. The results show that the system not only a- chieve prediction of the static and dynamic subsidence on single working face or multiple working face, but also achieve the 2D, 3D and dynamic visualization of the prediction result, which has a certain significance in surface subsidence prediction and control , ＂three - under ＂mining and other aspects.
