Abstract: To weakly consolidated and broken surrounding rock of 115-102 haulage roadway of Zhongheng coal mine，then small hole diameter peeping device was used in new tunneling roadway and section with large deformation，the reasons of roadway deformation was compared.The pre-stress distribution field of cable under different parameters were analyzed with numerical simulation software FLAC^3D.Based on the results of numerical simulation，combined supporting with rock bolt and cable schemes was determined for surrounding rock characters，which has the characters of high pretightening force，high strength，and high stiffness，then schemes was applied in underground and mine pressure was supervised，the results proved that the schemes could control surrounding rock deformation effectively.
