实施安全离层注浆的覆岩离层位置初探

Primary Discussion of Overburden Separating Location for Safe Grunting Bed Separating

通过对文献资料的分析,初步掌握了采动覆岩“三带”的破坏特征,离层产生的位置及条件。掌握了可用于注浆充填的覆岩离层,提出了在弯曲带接近于断裂带的离层中也不能实施注浆的观点。

The ＂Three-belt＂ damage characteristics of overburden strata induced by mining, the location and condition of strata separating are primarily acquired by the analysis of reference and information. The separating of overburden suitable for grunting is acquired. The viewpoint that no grunting should be implemented in separating location where wrap belt is near rupture belt is put forward.
