摘　　要：利用FLAC数值模拟软件,系统研究了不同断层倾角,不同断层带宽度和上下煤柱不同空间位置关系时受断层影响的地表移动规律,研究结果表明:当存在断层时,先开采上盘与先开采下盘的开采顺序不同地表移动是存在差异的,这种差异与断层倾角、断层带宽度、上下煤柱对齐程度有关。Based on the Fast Lagrangian Analysis of Continua （ short for FLAC） numerical simulation software, the laws of the ground subsidence and horizontal movement were studied systemically for the different bade, different width of fault and the special relations of the upper pillar and the lower pillar in vertical direction influenced by faults. The results show that the law of surface movement of mining is different when mining which wall first and the dispersion is correlative with hade, width of fault and the special relations of the upper pillar and the lower pillar in vertical direction.
