| Abstract: | In order to ensure the stability of the surrounding rock of the compound roof of the air intake roadway in the 2-105 working face of Ganhe Coal Mine,the control effect of the bolt(cable)pretension on the compound roof is analyzed by field test and numerical simulation,and the high prestressed bolt support scheme is designed.The maximum values of roof subsidence and two side displacement are 57mm and 64mm respectively,which ensure the stability of surrounding rock. |
