| Abstract: | The effect of roof water spraying on deformation and failure of roadway surrounding rock and its prevention were explored.Combined with specific engineering practice,on the basis of analyzing the effect of water spraying on the surrounding rock and through numerical simulation,this paper further explored the effect of roof water spraying on the plastic zone,stress and displacement changes of surrounding rock of the roadway,and then put forward a targeted combined support scheme of the roadway,so as to provide help for the long-term safe use of the roadway under roof water spraying conditions. |
