摘要
采煤工作面液压支架支护强度的确定是综采工作面岩层控制的研究重点之一,用3种方法对寺河矿3#煤层采高7m时大采高支架所需的工作阻力进行了分析计算,得出了液压支架的工作阻力数值。
Determining the strenght of hydraulic support on coal working face is one of the focuses in fully mechanized working face control ,the resistance on the hydraulic support in Sihe Mine #3 mining layer with 7 meters height is calculated by three methods , and the working resistance of hydraulic support is obtained .
