Study on deformation mechanism and control measures of deep soft rock roadway in kilometer deep mine

JPThis paper,based on Tangkou deep mine soft rock roadway,analyzes the reasons of roadway deformation and failure phenomena based on roadway failure characteristics;puts forward a program based on numerical simulation results of south roadway of the track that use bolt mesh and shotcrete + grouting to reinforce surrounding rock.The field application,which provides an effective method for the support of deep soft rock roadway,achieves good results.
