摘　　要：针对赵庄矿首采1301大采高工作面的工程背景,利用现场实测计算的手段,基于CDW-60支架监测系统对首采面矿压规律进行了监测,得出了直接顶、基本顶初次与周期来压步距参数。由于大采高工作面断块存在大回转空间的问题,着重对支架承载状态进行了研究。Taking the actual conditions of the first large height 1301 mining face in Zhaozhuang coal mine, by using field observation, the pressure law of the first mining face is monitored based on CDW-60 support monitoring system, step distances of the immediate roof and main roof fell down initially or periodically are obtained in first mining face. Impact of dynamic load is focused on for the problem of large swing space of the block in special large mining height face.
