矿井开采沉陷后最终地形等高线的生成及应用

摘要

The influence of coal mining on the ground facilities is not only related to the relative deformation of the ground surface, but also the influence of the subsidence value and the original terrain,the occurred deformation, the technical route that establishs the initial terrain matrix - mining subsidence value matrix - matrix addition operations"as the main line, generates underground coal resources development after final surface topographic contour map of is put forward, and combining different conditions, summed up the different specific operation method in this paper.%煤炭开采对地面设施的影响不仅与开采引起的地表相对变形量有关，还包括下沉值与原始地形、既有变形的叠加影响有关。本文提出了以“建立初始地形矩阵—开采沉陷值矩阵预计—矩阵相加运算”为主线，生成井下煤炭资源开发后地面最终地形等高线图的技术路线，并结合不同的情况总结了不同的具体操作方法。
