The invention relates to a total-section closed type deep-shallow
coupling yielding,
bolting-grouting and supporting method for an incompact and fractured soft-rock roadway. On the basis of a multilayered cooperative supporting principle, a spraying net combined isolating arch, an anchor rod extruding reinforcing arch, a total-section closed type grouting reinforcing ring and a deep
slurry diffusion reinforcing arch are respectively formed on surrounding rock of the roadway from shallow to deep finally, and are combined to form a multilayered effective combined arch by a suspension effect of a high-strength grouting anchor cable, advantages of yielding supporting,
bolting-grouting supporting and deep-shallow
coupling supporting are combined organically, bearing range, integrity and bearing capability of a supporting structure are improved obviously, a
control effect on deformation characteristics of
large deformation, high speed, long duration, wide destroying range,
peripheral pressing, obvious floor heaves and the like of the surrounding rock of the incompact and fractured soft-rock roadway is excellent, and various deformations of the surrounding rock of the incompact and fractured soft-rock roadway are controlled effectively. The total-section closed type deep-shallow
coupling yielding,
bolting-grouting and supporting method is particularly suitable for a large-section incompact and fractured soft-rock roadway of a deep well, is simple in work procedures and low in cost, and has
high field promotion and application value; and parallel operation can be realized.
