Abstract：In order to solve the floor heave deformation by the surrounding rock of roadway mining influence in the west two panel substation of GushuyuanMine ,with the surrounding rocks analysis of the roadway floor and side, the peeped result showed that surrounding rocks had lots of fractures , original anchored cable and rod supporting system had performed worse on the support effects.The treatment scheme was permanent support with high pressure grouting and high strength anchor cable ,through monitoring the displacement of surrounding rocks by the engineering practice , it was the final conclusion that the high pre -stressed anchor cable and grouting support is safe ,effective and economic way of supporting of kinetic pressure floor heave roadway.
