Abstract: Abstract: South wing of Gu Bei coal mine (6-2) rail roadway all anchor roadway engineering background, on the basis of referring to a large number of relevant literature, using a comprehensive research method, theoretical analysis, numerical simulation and field test, according to the actual situation of the south 6 coal rail roadway, the technology of rapid reinforcement of the full length anchoring grouting is proposed and successfully implemented by the hollow grouting bolt, the hollow grouting anchor, and the mine filling and grouting mortar, instead of the traditional use of heavy U - type shed to reinforce the surrounding rock, reduce the labor intensity of workers, speed up the construction schedule, and safe, efficient, low cost, easy to operate, and achieved industrial success.
