Abstract A new technique of pressing water to expand crack and injecting cement slurry to reinforce the crevice with open degree less then 0.1mm in rock is put forward. The feasibility and work mechanism of this technique，and calculation method of related parameters are analyzed by theory and testing in laboratory. As a result，the method to decide the related parameters of injecting cement slurry is given.
