Abstract
In order to guarantee the deformation of the dynamic pressure roadway in soft fractured surrounding rock mass to been effectively controlled, according to the "two high and one big" supporting principle, the support system of f high strength and high pre-stress yielding bolt was used, the application in Zaozhuang Coal Mining Group fucun coal company 3 402 fully ampliifed material lane showed that the maximum roof subsidence is 56mm, the maximum displacement near gob is115mm, the maximum displacement far from gob is 112mm, the design of the supporting system realized the broken rock dynamic pressure roadway safety supporting.关键词
