针对长山子煤矿1121综放面支架倒架、咬架的实际问题,通过对工作面地质条件、支架受力情况及设备情况的分析,建立工作面支架工作的力学模型,分析得到导致支架倒架的主要原因为顶底板松软、采高超高、支架上方空顶、支架防倒防滑装置不完备、个别支架侧护板故障和管理方面的因素,研究了解决三软大倾角工作面倒架问题较为有效的动态扶架技术。
According to the actual problems of support frame and bite frame of 1121 fully mechanized top coal caving face in Changshanzi Coal Mine, the mechanical model of working face support is established by analyzing the geological conditions, The main reason is that it is more effective to solve the problem of frame collapse in the three soft big-dip workface because of the soft roof, the high mining height, the top of the support, the unsupported anti-slip device of the support, the failure and management of the side support. Dynamic Trax Technology.
