Embodiment Construction

[0031] Such as figure 1 As shown, thin seam backfill coal mining is an organic synthesis of coal mining and mechanized solid backfill. The coal mining method of backfilling in the thin coal seam blasting mining face, compared with the traditional blasting mining face, the thin coal seam solid filling coal mining can realize the parallel operation of coal mining and filling under the cover of the same hydraulic support 1, and the thin coal seam solid filling coal mining face The arrangement is basically the same as that of the traditional blast mining face, the difference is that the filling face is arranged behind the coal face, that is, on the side of the goaf, and a solid filling material is arranged in the return air lane of the face. The conveyor, either a belt conveyor or a scraper conveyor, transports the solid filling material to the solid filling material scraper conveyor 8 . This arrangement of the working face can realize the parallel operation of filling and coal m...

Abstract

The invention relates to a coal mining method by filling on a blasting mining face of a thin coal seam and relevant equipment, belonging to the technical field of coal-mining and filling equipment of the thin coal seam. The method comprises the following main steps of: carrying out parallel operation on coal mining and filling under the protection of a same hydraulic bracket, and taking the relevant equipment such as the hydraulic bracket, a solid material scraping plate conveyer and a bridge-type stage loader as basis. The invention is applicable to coal mining operation by filling on the blasting mining face of the thin coal seam below 1.3m.

Description

technical field [0001] The invention discloses a coal mining method and related equipment for backfilling a thin coal seam blast mining working face, belonging to the technical field of thin coal seam coal mining and filling equipment, and specifically relates to a method for filling coal and related equipment for a thin coal seam blast mining working face. Background technique [0002] Coal mining not only provides energy for human survival, but also has a serious negative impact on the human environment. Coal mining not only forms a goaf underground, causing ground surface subsidence, causing damage to ground buildings and roads, but also a large amount of waste (mainly gangue) is discharged from the underground. First, it needs to occupy a large amount of land. polluted environment. So traditional coal mining methods are facing challenges. Academician Qian Minggao and other Chinese scholars proposed a new concept of green coal mining, [Green Mining Technology in Mining ...
