摘要: 采用RFPA2D和FLAC3D软件对龙门二1煤层底板岩体受采动影响的最大破坏深度及发育规律进行了数值模拟研究,并将煤层底板破坏深度的经验公式计算结果与数值模拟结果进行了对比。结果表明,数值模拟与经验公式计算结果基本一致。
关键词: 采动裂隙, 破坏深度, 发育规律, 数值模拟
Abstract: The maximum damage depth and its evolution regularity of the rock mass of Longmeng coal mine seam floor are numerical simulated by RFPA2D and FLAC3D software. Besides that, the numerical simulation results are compared with the results of the experience formula of coal floor damage depth. The research results indicated that,the numerical simulation results are consistent with the results of experience formula.
Key words: Mining-induced fissure, Damage depth, Damage evolution regularity, Numerical simulation
