Abstract: With the depleting of easy mining resources，the development of mining industry gradually turn into poor surrounding rock or the deep area.Taking the mining of soft surrounding rock masses for example，the deformation of roadways is fast，and the stability of roadways is poor.Therefore，in order to ensure the safety of roadways，the corresponding monitoring program based on JTM-V2000B pressure gauge and VWM vibrating wire displacement meter is designed for the problems of stress and deformation of soft rock.Combined with the actual situation of roadways，the special areas with worse stability should be paid more attention on monitoring.The program is applied in bauxite to monitor the construction of roadway in shale area beneath the riverbed.The monitoring data on site reflected the stress and displacement trends after excavation.The stress gradually transfer to the internal of surrounding rock masses for the large plastic deformation of soft rock，and the section of roadway becomes smaller and smaller.The monitoring results on stress and displacement can be used to guide the design and the timing of support in roadways.
