摘要
为解决矿山综采工作面的端头悬顶受采动应力影响大的问题,本文以平沟矿山0906综采工作面的工程实际情况为依据运用FLAC3D建立其皮带运输巷的物理模型。通过比较不同支护情况下围岩变形及应力特征。结果表明使用液压支架进行超前支护操作简单,增加了顶板的稳定性。保障了该矿安全生产的顺利进行。
In order to solve the mine fully mechanized working face end hanging roof under stress of mining, based on the actual situation of Pinggou mine 0906 fully mechanized working face engineering as the basis for the application of FLAC3D to establish the physical model of belt transport roadway, The deformation and stress characteristics of surrounding rock under different support conditions are compared. The result shows that the support with hydraulic support is simple, and the stability of roof is increased. Ensure the safe production of the mine go smoothly,
