The chain scraper conveyor is mainly used with coal miners, hydraulic supports, down-slot transferers, crushers, and belt conveyors to achieve coal mining, coal handling and other processes of loading and transporting coal in the fully mechanized working face Generally suitable for 0.8 "4.5 m coal seams, and can be used as the track and installation foundation for the operation of shearers and coal planers, as well as the fulcrum of the hydraulic support moving forward.
As the main energy consumption in China, coal resources occupy a dominant position in the energy consumption structure and production structure. How to increase the extraction rate of raw coal and reduce the waste of raw coal resources is a major issue that every coal mining company pays close attention to. The scraper chain conveyor designed and developed by our company is based on the user's fundamental interests and combined with the current coal mining status, the feasibility analysis of the middle section of the fully mechanized working face scraper conveyor is carried out to reduce the height of the central groove and reasonably improve In order to compare the recovery rate of the top coal, compared with the central trough of the traditional fully mechanized top coal caving face, it is assumed that the working face goes to 1500 m, the tendency is 200 m, and the height is reduced by 10 mm. Theoretically, the raw coal recovery amount can be increased by 30 thousand UI.
