摘要
单体液压支柱支护的回采工作面 ,应按照支柱与顶板相互作用的机理 ,根据具体的工作面顶板压力及支柱承载能力 ,计算合理的支护密度。合理支护密度即以最少的支柱来保证回采工作面顶板处于良好的状态。
This paper analyze in detail in hydraulic suported by individual props in working face.According to mechanism of props interacts with roof .It's known support capacity of roof pressure and props ,counts out rational support of density in particular working face.Rational supporf of density:It guarantec working face in a good state with least props.
