摘要
平顶山网状观测站测出了盆地的形状为正态曲面。盆地曲面弯度表达了开采损害程度,曲面的弯度分布展示了三维开采损害的布局。为'三下'采煤生产提出了更切合实际的空间开采沉陷的计算方法。这新方法很可能具有比其它方法解放煤量的潜力和对采动保护及采动区上建筑具有统观意义。
The shape of basin measured by Pingdingshan network station is a normal distribution surface, which represents the degree of deformation caused by underground mining. The author proposed a more practical method of calculating surface deformation for protecting surface constructions and water bodies.By using the new method more coal reserves could be extracted.
