摘　　要：大采高矿井的安全高产高效离不开对片帮冒顶的合理治理和防治,以晋煤集团赵庄煤业1306工作面为背景,并结合现场复杂地质情况,重点探究和分析了仰斜开采时煤层倾角对工作面煤壁片帮的影响规律以及防治措施。The high yield and high efficiency of large mining height mine can not leave reasonable control and prevention of rob spalling and roof falling. Taking 1306 working face in Zhaozhuang Coal Company of Shanxi Coal Group as background, considering the compli- cated geological conditions, this article focuses on the influence laws of coal seam dip on rib spalling and its prevention measures during up - dip mining.
