The invention discloses a method capable of repeated grouting and reinforcing surrounding rocks of roadway. The method includes the following steps: 1, confirming gross section size and selecting grouting materials according to displacement probably generated when a roadway reaches to stabilization on the condition of grouting, 2, confirming the depth and the array pitch of a grouting hole, seriflux ratio and grouting parameters, 3, adopting an air drill or a jumbolter to drill grouting holes on the periphery of the roadway, inserting a grouting pipe, and blocking gaps between an outer end of a blocking pipe and hole walls, 4, grouting in a sequence from a low-position hole to a high-position hole, 5, grouting in a separated-row and jumping mode to raise grouting effect, 6, when the displacement of the roadway increases to the fact that an obvious gap occurs, or acceleration or unstable deformation occur to thee roadway, conducting a new round of grouting. The method has the advantages that the roadway releasing energy through orderly deformation, thus needed supporting pressure is reduced gradually. Besides, broken surrounding rocks caused by constriction of the roadway are glued together timely though repeated grouting, thus a supporting structural body with good integrity and high strength always exists around the periphery of the roadway, and ultimately, the needed supporting force for maintaining stabilization of the roadway is reached or exceeded.
