Abstract
To the characters of soften easily and large deformation of weakly consolidated surrounding rock in shallow, broken influence factors of large section rectangle roadway under this kind surrounding rock condition were analyzed firstly, it taking 3-1 coal seam rectangle auxiliary transportation roadway of one coal mine in Dalate Qi of Ordos as background, then roadway stability under different driving sequence was simulated by software FLAC3D, roadway broken law and surrounding rock stress distribution law were studied, then the conclusion that surrounding rock stability was influenced largely by different driving sequence, some important supporting area of roadway surrounding rock under different driving sequence was put forward, and it references for roadway safety supporting.
