Abstract Based on roadway downhill crossing water-bearing fault fracture zone in Xinhe Mining Industry Corporation, In order to solve the water and rock broken problem, using grouting reinforcement technology, efficient leiyin modified polyethylene imine resin grouting material wave was adopted to conduct water-bearing fault fracture zone grouting reinforcement. results showed that the grouting water inflow reduced from 70 m3/h to 0.6 m3/h, security succeeded in driving through the fault fracture zone, the water cut mine provided reference for the similar conditions.
