A gangue backfilling system and method for laying transmission belts under rails

Abstract

A gangue backfilling system and method for laying transmission belts under rails, the pillow bracket is fixed on the upper end of the supporting beam, the upper surface of the pillow bracket is formed with an installation groove, and the walking track is fixed in the installation groove; the gangue conveying head wheel is in the return air At the head of the alley, the gangue conveying head wheel is fixed between two rows of supporting beams; the gangue conveying tail wheel is at the end of the return air tunnel, and the gangue conveying tail wheel is fixed between two rows of supporting beams; The gangue conveyor belt is connected between the gangue conveyor head wheel and the gangue conveyor tail wheel, and the gangue conveyor belt reciprocates along the gangue conveyor head wheel and the gangue conveyor tail wheel; the gangue conveyor head wheel is located at the gangue conveyor tail wheel On one side of the caster conveyor belt, the caster conveyor belt reciprocates along the caster transport head wheel and the caster transport tail wheel; the caster adjustment assembly is connected to the lower end of the caster part, and the bottom of the caster adjustment assembly is arranged above the walking track. The invention can continuously and continuously transport gangue to the rear of the coal mining face for backfill operation, thereby improving the backfill efficiency.

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
