| 摘 要： | 通过建立实体模型,运用FLAC3D软件对水力冲孔进行数值模拟,结果显示水力冲孔使应力峰值向深部转移,并且使煤体得到卸压;通过对不同孔径、不同埋深、不同煤层厚度进行冲孔模拟,并对这些不同条件下的垂直应力及位移分布规律进行了分析总结。

| Abstract: | Through the establishment of physical model,using FLAC3Dsoftware to simulate hydraulic flushing,the results show that the stress peak of hydraulic flushing transfers to the deep parts and the coal pressure gets relief.Then through the punching simulation of different diameter,different buried depth,different thickness of coal seam,the vertical stress and displacement distribution laws under different conditions are summed up. |
