The invention relates to the technical field of coal bunker construction, in particular to a vertical type double-container coal bunker and a safe construction method thereof.The double-container coal bunker comprises a bunker body, an outer container tightly attached to the inner wall of the bunker body, a bunker wall anchored by the outer container through a primary supporting anchor rod and a secondary supporting anchor rod, an inner container arranged in the bunker body, and the bunker wall anchored by the inner container through an anchor shed anchor rod; and a yielding gap is formed between the outer container and the inner container. The outer container of the coal bunker is actively supported through anchor net spraying, and the inner container is passively supported through U-shaped steel ring beams and reinforced concrete pouring, so that a yielding gap is reserved between the inner container and the outer container, deformation of a deep well vertical coal bunker body is effectively controlled, and
