软弱围岩锚网索支护数值模拟分析与应用

THE ANALYSIS BY NUMERICAL SIMULATIONS OF SUPPORT WITH BOLTS AND NET IN THE SOFT ROCKS AND APPLICATION

文章结合缸沟煤矿轨道下山工程地质实际条件,提出了具体的锚网索支护技术方案,运用FLAC2D数值模拟软件,深入分析了锚网索对围岩整体结构的加强效果,验证了锚网索在不同支护时期的支护理论。强调锚网索在支护体系中的重要作用。对今后煤矿运用该支护技术提供了指导作用。

The article based on the GANGGOU MINING geological condition of the down roadway, put forward the embody preject . Then by the numerical analyses software FLAC2D, deeply analyzed of the support effect by bolts and net to the whole structure of surrounding rocks, validate the support theory of bolts in vary period. Emphasize the net is very important function in the support system. It has some guidance meanings in coal mine use this technique in the aftertime.
