At the turn of the last century, bolt supporting of coal roadway had rapidly developed with the applied range of bolt stretching continually. The bolt supporting in roadway has been implemented widely. But until now, there is no reliable theoretical support or appraisal system on the design of bolt supporting roadway and the evaluation of supporting conditions. Supporting effect is tested only by practice and roof-fall accidents take place repeatedly. This paper conducts the research on the bolt supporting parameters in No.315 transportation-up-hill roadway of Nan Ye Coal Mine with numerical analysis method; it is discovered that numerical analysis can be a good way to predict and evaluate roadway supporting effects to be worthy popularizing.
