摘　　要：9711工作面为开元矿首个大采高综采工作面,该工作面煤层结构复杂,开采难度大,通过理论分析、现场测试及验证,对开元矿大采高工作面矿压规律进行了研究,建立了开元矿大采高工作面“悬臂梁+铰接岩梁”覆岩结构模型,针对煤壁片帮原因和影响因素提出了加快工作面推进速度、加强支护质量管理、控制割煤质量和采高等技术措施,效果良好。Aiming at the complex coal seam structure at 9711 fully-mechanized working face with large mining height in Kaiyuan mine,the paper studies the law of mine pressure,establishes the structural model of“cantilever-beam-and-hinged-rock-beam"”through theoretical analysis,field test and verification,and puts forward the measures of speeding up the advance of working face,strengthening the quality management of support,controlling the quality of coal cutting and mining height based on the reasons and influencing factors of coal wall spalling.
