| Abstract: | Dongguashan copper mine has such characteristics as high stress(30~38MPa) and rockburst possibility.On the basis of in-site survey of rock stress,physical and mechanical tests of rock,investigation of rock mass structure,numerical simulation and engineering practices,the unstable mode of the laneways that located in different rock mass was analyzed carefully.Supporting measures and controlling parameters were provided according to the rock characters,engineering position,function and possible unstable modes of the laneways. |

| Keywords: | deep mining high stress laneway unstable mode rockburst combined support |
