摘要
从实验结果和现场实践出发 ,讨论了老顶剪切型破坏的条件和特点以及顶板运动破坏的拱结构特征 ,指出了从应力和岩层的结构破坏两个不同角度所提出的拱模型有着不同的内涵和特点 ,最后 ,讨论了拱结构发展到地面时的特点。
Based on the simulated test and field practice, this paper studies the condition and characteristics of main roof shearing failure, and the feature of arch structure during strata movement and failure. The arch model has different intention and characteristics established from stress and strata structure failure. At last, the paper studies the features when arch structure develops toward the surface.
