随着急倾斜工作面采矿活动的进行，工作面在倾斜方向会产生底板破坏滑移。根据倾斜砌体结构理论，支架在倾向正压状态下，以及受到底板滑移破坏作用会发生失稳。为研究该种失稳方式，借助边坡失稳问题分析方法，求出底板安全系数 F。在安全系数 F ＜1情况下，分析工作面支架在倾向正压以及底板破坏滑移共同作用下的失稳模式。得出支架滑移和顺向倾倒两种失稳模式。采用数值模拟分析急倾斜工作面底板破坏滑移区域，发现底板应力主要集中在工作面中上部，并且当倾角越大，工作面底板破坏越严重。研究结果表明，工作面中上部是支架在倾向正压及底板滑移共同作用下发生失稳的高发区。

Steep working face in inclined direction produce floor damage sliding with the steep inclined working face mining activities .According to the theory of inclined masonry structure ,support produce instability under the influence of the tendency of positive pressure state and floor sliding failure action .In order to study this kind of buckling mode ,the floor safety factor F is obtained by the method of slope analysis .In the safety factor F<1 case ,analysis of working face support in the tendency of positive pressure and sliding instability under the common action instability .Scaffold slippage and consequent dumping two buckling mode .Adopt the method of numerical simulation analysis steep damage sliding floor area ,found that stress mainly concentrated in the face of the upper floor ,and with the bigger dip Angle ,the greater the face slab destruction serious .The result shows that the high incidence area of support instability is the upper face under the influence of the tendency of positive pressure state and floor sliding failure action .
