用时间序列分析法确定工作面的合理支护强度

Determining the reasonable support density on working face by means of time series analysis

本文建立了采场支护系统的灰色动态模型,并结合汾西矿务局高阳煤矿4202扩工作面应用实例进行了验证。

This paper established the grey dynamic model of support system in stope,and found thereasonable support density by means of time se-ries analysis. It is rather approximate to thatdetermined by adjusting pressure test on work-ing face when compared with each other.
