根据余吾煤业S1206工作面的片帮问题利用压杆模型将煤壁简化为一端铰支和一端固支的受压杆，计算得出大采高煤壁最易失稳的位置在0.35倍采高处，然后采用FLAC3D数值模拟软件，分别对煤层采高和支架工作阻力进行了数值模拟研究。最后结合余吾煤业S1206工作面地质条件得到防治煤壁片帮的措施，并取得良好效果。
根據餘吾煤業S1206工作麵的片幫問題利用壓桿模型將煤壁簡化為一耑鉸支和一耑固支的受壓桿，計算得齣大採高煤壁最易失穩的位置在0.35倍採高處，然後採用FLAC3D數值模擬軟件，分彆對煤層採高和支架工作阻力進行瞭數值模擬研究。最後結閤餘吾煤業S1206工作麵地質條件得到防治煤壁片幫的措施，併取得良好效果。

Based on the wall caving problem in Yuwu coal industry S1206 working face, using shaft model reduces the rib to one end hinged and clamped by the lever end. Calculated the most vulnerable position for instability in large mining height coal wall is in mining height 0.35 times. Then use simulation software FLAC3D,conducted numerical simulation study for coal mining height and working resistances of supports respectively. Finally, through Yuwu S1206 working face geological conditions, got the wall caving prevention and achieved good results.
