Gangue transporting and backfilling system and method for laying transmission rubber belt under rail

Abstract

The invention relates to a gangue transporting and backfilling system and method for laying a transmission rubber belt under a rail. A sleeper support is fixed to the upper end of a support cross beam, a mounting groove is formed in the upper surface of the sleeper support, and a walking rail is fixed to the interior of the mounting groove; a gangue transporting conveying head wheel is located atthe roadway head of an air return roadway and is fixed between two columns of support cross beams; a gangue transporting conveying tail wheel is located at the roadway tail of the air return roadway and is fixed between the two columns of support cross beams; a gangue transporting conveying belt is connected between the gangue transporting conveying head wheel and the gangue transporting conveyingtail wheel, and the gangue transporting conveying belt reciprocates along the gangue transporting conveying head wheel and the gangue transporting conveying tail wheel; a gangue throwing conveying head wheel is located on one side of the gangue transporting conveying tail wheel, and a gangue throwing conveying belt reciprocates along the gangue throwing conveying head wheel and a gangue throwingconveying tail wheel; and a gangue throwing adjusting assembly is connected to the lower end of a gangue throwing part, and the bottom of the gangue throwing adjusting assembly is arranged above the walking rail. According to the gangue transporting and backfilling system and method, gangue can be continuously conveyed to the rear part of a coal face for backfilling operation, so that the backfilling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transportation in the return air level roadway of the underground section of the coal mine, and in particular relates to a gangue backfilling system and method for laying transmission belts under rails. Background technique [0002] The filling coal mining method is a coal mining method that uses filling materials to fill the goaf of the coal mining face to control the movement and deformation of the rock formation. The method can alleviate the appearance of mine pressure caused by the support pressure of the working face, improve the maintenance status of the stope and the roadway, effectively reduce the subsidence and deformation of the ground surface, increase the recovery rate, and protect the ground buildings, ecological environment and water body. There are many filling materials available for filling coal mining method, such as river sand, gangue, fly ash, waste oil shale, etc. Among them, gangue i...

AI Technical Summary

Problems solved by technology

[0005] First, when mining trucks are used to transport gangue backfill in the return air level roadway, the transportation of gangue used for backfilling is discontinuous, resulting in intermittent backfilling, reducing backfilling efficiency and affecting the normal production of the working face

[0006] Second, the track inside the return air alley needs to be responsible for the task of transporting materials and gangue at the same time, which will make the traffic in the return air alley heavy and increase potential safety hazards

[0007] Third, the transportation volume of mine vehicles is small, it is difficult to meet the filling requirements of the mining face, and the backfilling speed and coal mining speed are unbalanced, which affects normal production
