| Abstract: | In the design of applying the numerical simulation method to return roadway bolt support on working face in some mine, the author builds a numerical model that based on real condition, rules of designing numerical model and geological mechanics parameter of the regional terrain as the simulated limiting condition by geological data research in spot. Also, the author advances five bolt disposal methods as well as simulates and analyzes output charts (mainly to analysewall rock and around bolt stress), so as to rational support program. |
