摘要
以新元煤矿9108综采工作面为实例,对该工作面支架初撑力、工作阻力等进行现场监测及分析;监测数据表明,工作面初次来压步距约40 m,周期来压步距平均为22 m,工作面来压在工作面布置方向及推进方向上均具有明显的分区特点;生产过程中支架普遍初撑力不够,需加强现场管理;支架工作阻力属于正态分布,整体工作状态较好。
By field monitoring and analysis of the support setting load and working resistance,it is found that the division characteristics of weighting occur in the layout and advancing direction of working face with 40 m first weighting steps distance and average periodical weighting steps distance of 22 m,and support working resistance belongs to the normal distribution in good working conditions with inadequate setting load.
