Abstract Based on engineering practice in Wuyang coal mine, the mechanical properties of roof rock
has been obtained by the triaxial compression experiment of confining pressures step longtime loading,
and the surrounding rock visco-elasticity property of supporting roadway has been analyzed, and con-
trolling principle of surrounding rock has been proposed for controlling deformation of coal rise entry in
supporting practice. Four conclusions were d
