| 摘 要： | 为了研究特定煤层赋存条件下大采高工作面在推进过程中的矿压显现规律,采用数值模拟的方法模拟两层煤之间有一层厚夹矸和坚硬顶板的大采高工作面的矿压显现规律,模拟过程中采用计算模型改变命令实现了工作面的连续推进.通过数值模拟得到了工作面顶底板位移及应力分布规律.

| Abstract: | In order to study the strata-pressure behaviors under the special occurrence of coal seams during the advancing of fully-mechanized working face with large mining height,the strata-pressure behaviors were simulated for the working face composed of two coal seams with intercalated thick gangue and hard roof.During the numerical simulation,the continuous advance of working face was realized by the change of program commands.The laws of displacement of coal seam roof and floor and the stress distribution were ... |
