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。
The FLAC numerical simulation software was used to systematically study the law of surface movement under the influence of faults when different fault dip angles, different fault widths and different spatial positions of upper and lower coal pillars. The results show that when there is a fault, There is a difference in the movement sequence of the lower plate between different ground movements, which is related to the dip of faults, the width of fault zone and the alignment of upper and lower coal pillars.
