摘要
以具有坚硬顶底板,倾斜软煤层顶板初次失稳的实际问题为背景,通过对岩石沿结构面裂纹生成与扩展而形成的岩梁初次失稳破坏形式进行了理论与实验研究。为今后进一步研究提供了科学的依据。
This papers based on the problem of the first instability of coal seam top in the hard coal seam top , hard coal seam floor and soft coal seam. The study on the first instability of rock beam resulting from crack creation and development along structural interface. provides the theoretical basis for the further work
