Abstract
in construction of the rail entry of 23 206 fully mechanized caving face, the inlfuenced by the fault, the roof rock is broken, the erecting shed support was used , when driving 50 meters, occur roof fall accident, it is dififcult to drive forward. After the Marithan grouting technology of advance reinforcement, the stability of tunnel surrounding rock are greatly improved, safety coefifcient is increased, the tunneling work can be carried out smoothly.关键词
