摘要
通过FLAC-3D模拟软件,以中能煤业3号煤层大采高2301工作面现场模拟为例,对其开切眼进行建模,并模拟了工作面推进过程中工作面两端头与中部的垂直和水平应力。结合现实工作面矿压情况,对工作面的开采具有实际的应用和指导价值。
By FLAC-3D simulation software, the paper has modeling the open-off cut of 2013 high mining working face of No. 3 coal seam in Zhongoeng Coal company. And has simulating the vertical and horizontal stre.ss of both ends of tile head and middle of Working face during the process of mining. Combined with the reality Face Pressure,It has actual value of application and guiding for working face mining.
