开采沉陷数据的可视化研究

Visualization Research of Mining-Subsidence Data

利用C#语言实现了煤矿开采地表移动与变形等值线(下沉、倾斜、曲率、水平移动、水平变形)的绘制,在此基础上进行了影响区域任意两点间的剖面线的绘制,基本实现了开采沉陷数据的可视化,可对采区上方建筑物进行了破坏等级划分,从而判别建筑物是否受到地下开采的影响以及受到开采影响的程度。

A C#--based method is introduced to produce isoline maps for coal mining induced surface movement and deformation such as subsidence, incline, curvature, horizontal movement, and horizontal deformation. Profile line between any two points in an affected area can be derived, and mining subsidence data can be visually presented. Based on the damage gradation criteria for the buildings above a mining area set by the State Bureau of Coal Industry, impacts of underground coal mining on buildings and their degree can be evaluated.
