The invention discloses a method for supporting a lamellar soft rock laneway by wire rope anchors. The method comprises drilling a plurality of anchor holes in the lamellar rock, controlling the distance between two adjacent anchor holes to be in the range of 700-1,000mm; uniformly mixing cement, white cement, water reducer and gypsum according to weight percentages, feeding into packaging bags, and forming cement rolls; immersing the cement rolls into water, and then feeding into the anchor holes; inserting the wire rope anchors into each anchor hole; and fixing the openings of the anchor holes, jointing the anchors in the direction of the laneway, and hinging the anchors by rope clips, so as to support the lamellar soft rock laneway. According to the method provided by the invention, the supporting structures are closely combined with the surrounding rock, not only the free deformation and the loose damage of the surrounding rock are avoided, but also the structure can adapt to certain deformation of the surrounding rock so that the deformation pressure on the supporting structures is not too high, and the inclined lamellar weak tuff is reinforced effectively, so that a new method is provided for supporting the weak lamellar soft rock laneway.
