中文摘要：

为了弄清楚不同倾角煤层开采围岩变形规律且进行合理的支护，应用数值模拟计算与模型试验相结合的研究方法，就煤层倾角对深部沿空巷道围岩变形的影响进行了研究，发现沿空巷道两帮及顶底移近量随煤层倾角变化的曲线呈现马鞍形；当煤层倾角在20°时，两帮及顶移近量最小，而倾角小于或大于此角度，两帮及顶底移近量均增大；马鞍形曲线的形状随采深的变化稍有变化，当采深逐渐加大时，大于20°一侧的曲线逐渐抬高，即大于20°与小于20°相同度数时，采深度数大的移近量更大一些。

英文摘要：

In order to find out the deformation rule of surrounding rock dm＇ing mining coal seams with different dip angle and implement reasonable support, numerical simulation and model experiment were applied to research the influence of dip angle of coal seam on surrounding sock deformation of gob - side roadway. It is found that the changing curves of the horizontal convergence and vertical convergence of gob - side roadway with dip angles of coal seam present saddle shape. The results show that when the dip angle of coal seam is 20°, the horizontal convergence and vertical convergence ore the smallest, when the dip angle is smaller or bigger than 20° ,the convergences are both increasing, however, the saddle shaped curve changes slightly with the depth of mining ; Whether the dip angle of coal seam is bigger than 20° or less than 20°, the convergences with the greater depth of mining are larger when the dip angles are the same.
