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...
