The invention relates to fracture zone soft-rock roadway advance supporting technology. The technology includes following steps: step 1, drilling a hole in a roadway section top profile line, whereinthe drilled hole and a horizontal plane form an angle of 1-2 degrees; step 2, inserting round steel into the drilled hole; step 3, setting up a first-stage steel frame in front of a roadway section, and welding the first-stage steel frame with the round steel; step 4, blasting to form a roadway; step 5, digging drainage trenches on two sides of the undersurface of the roadway formed by previous blasting, and hanging a meshwork carpet which is already made well onto a top plate of the roadway, wherein upper-layer fabric and lower-layer fabric can be synthesized by one or multiple of nonwoven cloth, woven cloth, machine-woven cloth or knitted cloth; step 6, repeating the steps 4 and 5, and stopping blasting until a distance away from the remaining round steel in the drilled hole is smaller than the distance between adjacent two steel frames to complete a circle; step 7, entering next circle until roadway construction is completed. By the technology, dripping water is utilized fully, supporting speed is accelerated, collapse is prevented, and construction efficiency is improved.
