Abstract：Aiming at the impact of main roadway passing through DF16fault on the fracture zone in Liujiayao Coal Mine, the prevention of water inrush and the stability of surrounding rock are studied, the concrete grouting wall is used to pre-dam water blocking technology, and the combined support technology of pre-stressed anchor bolt, anchor cable and U steel roof is adopted. Result shows that, the technology effectively solves the problems of water control and support, and achieves favorable technical and economic result. The study can provide references and experience for the support design for similar roadways passing though fault fractured zone.
