The surrounding rock of roadway tends to behave the characters of soft rock with the increase of mining depth,so the research on support technology of deep soft rock roadway is very important for locale construction.Based on the in-situ measure,this paper adopts researches the support technology of roadway in deep soft rock using data analysis method and combining with the theoretical basis.The researched result shows that for the support of soft rock roadway the soft character of rock should be made use of and the surrounding rock should be allowed become plastic so as to exert the self's load bearing capability of surrounding rock.In the practice,through choosing the best time of second supporting and controlling the second deformation of surrounding rock based on the actual measure,the good economy effect has been obtained.
