　　针对1523大倾角工作面进入孤岛区后支架-围岩事故频发的开采难题，探析了支架-围岩事故频发原因，采用现场测试与回归计算分析方法研究冒漏片帮与支护参数的相关性关系，并提出了支架故障诊断、防倒防滑装置、稳定性控制指标和设备操作工艺等综合控制技术。结果表明：采用该技术后端面顶板冒高大于0.40 m的冒顶频率由76%减小到16%，端面煤体片深大于0.5 m的片帮频率由72%减小到23%，未发生恶性片帮冒顶与支架倒架现象，有效解决了大倾角孤岛面支架-围岩失稳的控制难题。

In allusion to the problem of support–surrounding rock accidents when No.1523 fully mechanized face with large inclination advanced to the island district, we analyzed the cause of the ac-cident. The relative relationship between roof fall and rib spalling and support parameters was studied by spot testing and regression analysis. Then the synthetical control technology including fault diagnose, device for anti-falling and anti-slipping, stability control indices, equipment operation process and so on was put forward. Result shows that the frequency of roof fall height over 0.40 m decreased from 76%to 16%, and the frequency of rib spalling over 0.50 m decreased from 72%to 23%after the technology was applied in coal face of No.1523. So no serious accidents of rib spalling and roof fall occured, the control problem of support–surrounding rock instability in the coal face of large inclination and island district were solved.
