The invention discloses a segmented grouting hollow grouting anchor cable and a using method. The hollow grouting anchor cable comprises a screwed plug, an anchor cable body, a lock, a tray and an external grouting stop plug; the anchor cable body comprises a plurality of steel strands; the plurality of steel strands are spirally wound on a grouting pipe I and a grouting pipe II; the anchor cablebody is connected into anchor cable holes in the tray and the center of the external grouting stop plug; a grouting pipe III is connected into a reserved hole of the external grouting stop plug in a penetrating mode; and slurry outlets of the grouting pipe I, the grouting pipe II and the grouting pipe III are different in position, during usage, the three slurry outlets correspond to three different positions of a grouting anchor section of a coal and rock mass correspondingly, and thus segmented grouting operation on the grouting anchor section is achieved. The anchor cable is ingenious in design and simple in structure, slurry enters different formed grouting sections, the balance of the front grouting pressure is ensured, the grouting amount of deep rock fractures is increased, slurry is uniformly diffused into the surrounding rock fractures, and the grouting anchoring effect of shallow surrounding rock mass is ensured through secondary grouting..
