基本顶断裂位置对小煤柱沿空掘巷稳定性影响

Influence of Fracture Position of Basic Roof on Stability of Small Coal Pillar Gob-side Entry Driving

为掌握基本顶断裂位置对小煤柱沿空掘巷围岩稳定性的影响规律,采用离散元法对2种断裂位置小煤柱沿空掘巷围岩稳定性进行数值模拟研究,以求获得规律性的结论。

To master the influence law of the main roof＇s fracture location on the stability of gob-side entry driving with small pillar,tries to obtain a conclusion of the law through numerical simulation research on the stability of surrounding rock of small coal pillar gob-side entry driving in terms of two fracture positions via discrete element method.
