摘    要:通过实测发现了厚砂土层载荷传递现象,提出了顶板关键层载荷层载荷传递因子的概念。运用动态载荷相似材料模拟实验,得出了初次来压期间厚砂土层的“拱形”和“弧拱形”破坏特征,建立了载荷传递力学模型,得出了初次来压载荷传递因子的计算公式。

关 键 词:浅埋煤层  厚砂土层  初次来压  载荷传递因子

Abstract:Through the site measurement, the load transmitting phenomenon of thick sandy soil on the key roof stratum is found; and the concept of load transmitting factor of key roof stratum load layer is established. By simulating model test of dynamic load transmitting, the “arch type” and “thick arc shell” damage form of thick sandy soil layer upon shallow coal seam in first weighting is revealed. Finally, the formula of load transmitting factor during first weighting is set up. Those research and discovery will make progress on mined soil damage mechanism and dynamic roof structure theory.
Keywords:shallow coal seam  thick sandy soil layer  first weighting  load transmitting factor
