大采高液压支架支护参数与支护方法研究

Study on Support Parameters and Support Methods of Hydraulic Support with Large Mining Height

为了及时有效地支护大采高工作面煤壁和顶板,在对大采高液压支架支护原理分析的基础上,给出了支护参数的确定方法,提出了"先调整后自动"操作电液控制系统控制液压支架完成降架—移架—升架工序的方法。总结出:"快、直、正、严、紧、净"的六字液压支架支护要诀。

In order to timely and effective support with large mining height working face coal wall and roof, large mining height hydraulic support supporting principle analysis based on the given branch support parameters determination method proposed "adjust the automatic" operation of electro-hydraulic control system control hydraulic support to complete the landing gear-shift frame or frame process method. Summed up: "fast, direct, positive, strict, tight and clean" six word hydraulic support tips.
