| Abstract: | Aiming at the local roof leakage when the 5107 roadway passes F4 fault,which leads to the difficulty of roof maintenance and the poor effect of traditional bolt(cable)support,through the analysis of the roof falling mechanism at the fault,this paper puts forward the combined support measures ofgrouting+artificial roof+advanced pipe shed,which controls the roof leakage,ensures the roof stability in the leakage area,and achieves good results. |
