通过130602综采工作面矿压在线监测系统实时数据联系工作面现场实际，对工作面顶板直接顶及老顶初次来压步距进行分析研究，总结出本矿区直接顶及老顶初次来压步距，为确定工作面超前支护范围及今后矿井综采工作面安全回采提供了参考依据。%Based on the real-time data of the mine pressure on-line monitoring system of 130602 fully mechanized working face and combined with the practice in the working face, the first weighting step of the immediate roof and main roof of the working face roof are analyzed, and then the first weighting steps of the immediate roof and main roof of this mining area are summarized, which provide reference for the determination of the forepole scope of the working face and the safe recovery of the working face in the future.
