摘　　要：断层带岩体一直是煤炭开采过程中受关注的区域。随着能源紧缺问题的进一步突出,煤柱也日益成为被关注的主要区域。利用FLAC-2D数值模拟软件对断层带开采对底板和断层切割的含水层的岩体的应力和位移的变化进行模拟分析,提出了断层煤柱留设的建议,为科学留设防水煤柱提供依据。Fault zone is an important region during coal mining.With the more serious energy shortage,coal pillars are also becoming major areas of concern.The numerical simulation software FLAC-2D is used to simulate the change rock mass of the stress and displacement of the aquifer,the aguifer is cut by floor and fault with mining in fault zone.The suggestion of retaining fault coal pillars is proposed to provid a scientific basis for retaining reasonable waterproof pillars.
