浅埋煤层厚沙土层顶板关键块动态载荷分布规律

Simulating test on damage regularities of thick sandy soil layer and load distribution on key roof block in shallow coal seams

    摘要
  • 摘要: 通过动态载荷传递相似模拟实验方法,对浅埋煤层顶板厚沙土层的采动破坏机理及对顶板关键块的载荷传递进行了研究,得出了顶板关键块上的动态载荷分布规律,为揭示载荷传递机理和建立顶板动态结构理论奠定了基础

     

    Abstract: Through the dynamic simulating model test,the damage caused by mining of thick sandy soil layer upon shallow coal seam is revealed.It is also found that the regularities of dynamic load distribution on the key roof blocks.This discovery will make progress on load transfer mechanism and dynamic roof structure theory.
