In order to seek for new support means of roadway in loose and soft rock, after analyzing the deformation characteristics of loose and soft surrounding rock, an enhanced pre - support technique is put forward. The some parameters of rock are gained according to the practice engineering. The numerical simulation, comparison and analysis of four kind of pre - support means are carried out by sue of FLAC, the results show that enhanced pre - support technique is optimum for loose and soft surrounding rock of roadway.
