摘要
文章针对轩岗煤电焦家寨煤矿51109工作面进行支架载荷观测,利用安装在综采液压支架立柱上的圆图压力自记仪进行支架工作阻力的描绘,收集并整理支架初撑力、最大工作阻力、时间加权平均阻力数据,得出顶板周期来压特征,并提出有效控制顶板的建议和措施。
The study observes the support load of No. 51109 working face in Jiaojiazhai mine. Pressure recording instrument is used to describe the support working resistance. And the data, including setting load, maximum working resistance, time weighted average resistance, are collected and organized to calculate periodic roof weight characteristics. Besides, effective suggestions of roof control are presented.
