Embodiment Construction
[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, All other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.
[0026] A complete set of support equipment for roadway excavation with weak filling is composed of a mobile support section 1, a movable support long pipe 2 and a plurality of standard support sections 3. The mobile support section 1 is for the support when the excavator faces and follows the excavation. The tunnel face moves forward and moves forward. The standard support section 3 is the permanent support of the roadway, and it is erected and installed one by one following the forward...

The invention discloses complete supporting equipment for roadway tunneling in soft filling bodies, which consists of a movable supporting section, a movable supporting long pipe and a plurality of supporting standard knots, the movable supporting section is a temporary support for a tunneling tunnel face and advances along with the forward advancing of the tunneling tunnel face, and the supporting standard knots are permanent supports for roadways and are used for supporting the tunneling tunnel face along with the forward advancing of the tunneling tunnel face. And the movable supporting sections and the movable supporting long pipes are erected and installed one by one after moving forwards, and the movable supporting long pipes are used for temporarily supporting the unsupported area between the movable supporting sections and the supporting standard sections. The tunneling and supporting equipment for the roadway in the soft filling body has the advantages of being good in supporting effect, high in strength, high in supporting operation speed, high in efficiency and low in strength.
Description
technical field [0001] The invention belongs to the technical field of tunnel excavation in underground mines, and in particular relates to a complete set of support equipment for tunnel excavation in a soft filling inner body. Background technique [0002] The backfill mining method has the advantages of safe mining operation, low mining loss rate and dilution rate, reduction of overburden and surface settlement and deformation, reduction of tailings and waste rock and other mining and solid waste surface storage, etc., and has become the most mainstream and application. The widest range of mining methods. As the backfill mining method is used more and more widely and more frequently in the field of underground mining, with the increase of the backfill mining area and the progress of the backfill mining, more and more mines in the operation area are mined by backfill mining. The empty area is filled, and the upper and lower walls or the top and bottom of the ore body are s...
