| 摘 要： | 为研究断层活化因素的关联度,采用FLAC3D软件、DPS软件、SPSS20软件,通过数值模拟、灰色关联度分析以及单因素分析相结合的方式,列举了8种影响因素,分析了其对断层活化的影响程度,结果表明:所有因素关联度排序为采宽>采高>断层倾角>断层带宽度>采深>断层落差>回采步距>回采速度,且前四者对断层活化的影响程度远大于后四者。其中断层倾角、断层带宽度对断层活化的影响程度最大,确定为主控因素。分析了两者对断层活化的具体影响,发现倾角越大断层越易活化,断层带宽度越大断层越易活化。

| Abstract: | To study correlation between fault activation factors has used FLAC3D,DPS and SPSS20 softwares,through combined numerical simulation,grey correlation analysis and single factor analysis approaches,enumerated 8 impacting factors,analyzed their impacting extent on fault activation.The result has shown that the sequencing of all factors is:cut width>shear height>fault dip angle>fault zone width>working depth>fault throw>extraction independent advance>drawing rate,while impacting extent of the former four is far greater than the latter four.In which,impacting extents of fault dip angle and fault zone width are the largest two,thus the main control factors.The paper has analyzed the specific impacts from the two on fault activation found that the larger the fault dip angle and fault zone width,the easier the fault activation. |
