摘要
通过综放工作面液压支架阻力观测,分析了支架阻力分布特征,并采用小波变换分析支架工作阻力,分析出来压周期性规律,追溯某点对应数据所对应的压力时间和步距,更好地预警来压的最值点。
Via viewing the obstruction of hydraulic pressure trestle, analyse the characteristic of hydraulic pressure trestle ,and use little wave vary analyse the obstruction of hydraulic pressure trestle, thereby analyse the periodically regularity, review corresponding time and step distance of some point,predict the maximal value of the coming pressure.
