摘　　要：阐述了运用FLAC3D数值计算软件和现场观测方法,对甘肃省王家山煤矿大倾角厚煤层走向长壁综放采场矿山压力进行研究的情况。研究认为,大倾角综放,工作面沿倾斜方向矿压分布具有明显的不对称性,综放面液压支架的防倒防滑是保证工作面正常推进的一个技术难点。This paper research the ground pressure of the Long--wall Full--mechanized caving mining field on strike of steeply thick coal seam of Gansu Wangjiashan coal mine by using the FLAC3D numerical calculation software and field observation. The distribution of strata behaviors on large inclined angle fully-mechanized sublevel caving face has obvious asymmetry along the inclination direction of coalface. Anti-toppling and anti-skid measure for hydraulic support in large inclined angle face is a technical difficulty to guarantee the usual advance of coalface, where should strengthen the upper and middle part of hydraulic support especially.
