Abstract

The invention discloses a mine laneway supporting steel arch and a mounting method thereof. The mine laneway supporting steel arch comprises a middle steel arch assembly, the two sides of the middle steel arch assembly are each provided with a triangular support, the middle steel arch assembly comprises an arched vault unit, the two ends of the vault unit are each provided with a piece of roadway two-side long-strip U-shaped steel, the vault unit and the two pieces of roadway two-side long-strip U-shaped steel jointly define an arch with an opening in the lower portion, the two ends of the vault unit are connected with the upper portions of the two triangular supports respectively, the lower ends of the two pieces of roadway two-side long-strip U-shaped steel are connected with the lower portions of the two sets of triangular supports respectively, and a closed triangular area is defined by one set of triangular supports and the adjacent piece of roadway two-side long-strip U-shaped steel. The technical problem that in the prior art, a roadway support is prone to causing local overall sinking of a roadway is solved.

Description

technical field [0001] The invention belongs to the technical field of roadway construction support, and in particular relates to a steel arch frame for mine shaft roadway support and an installation method thereof. Background technique [0002] After the three-core arch roadway in the underground mine is excavated and formed, there are many support methods. Among them, the steel arch is used for support, which is a relatively high-cost and relatively stable support method. [0003] In the prior art, when steel arches are used for support, the following two structures are included: [0004] (1) The section steel is used to close to the roadway rock wall and form a circle for support. This method relies on the rigidity of the formed steel to form passive resistance to the surrounding rock pressure around the roadway, and is a more effective passive support method. The disadvantage of this structure is that, with this support structure, the steel finally transmits the force ...
