The study of supporting parameter design of bolt in the coal tunnels of Yujialiang coal mine
Abstract：This thesis based on the problem that existence in supporting parameter design of bolt in coal tunnel. Through theoretical analysis and field experiment associate with the condition of Yujialiang coal mine. We find out a new appropriate supporting parameter design method of bolt that appliance to the coal tunnels of Yujialiang coal mine, as the design method of ＂geomechan- ics assessment -numerical simulation-initial design-field observation--revise design＂. We measured loose ring of surrounding rock of roadway. , Through theoretical analysis and test analysis the loose circle of law. We design reasonable roadway bolting support parameters, through the analysis of field test of bolt, effective control of the tunnel distortion. Good results have been achieved.
