Abstract

The invention provides a fully-mechanized coal mining supporting and throwing type gangue filling hydraulic support. The installation mode of a bottom unloading scraper conveyor on the rear portion of a traditional fully-mechanized coal mining gangue filling hydraulic support is changed into a bearing mode from a hanging mode, the degree of freedom of the scraper conveyor on a bearing platform is greatly increased, chain ring connection between the scraper conveyor and the hydraulic support is avoided, and the hydraulic support is not affected by the width of a working face; and meanwhile, the width of a fully-mechanized coal mining gangue filling working face is increased, the structure and the size of a gangue throwing belt conveyor are optimized, the gangue filling efficiency and the filling roof contact rate are improved, the frame tail filling empty roof distance is reduced, and the gangue throwing inclination, the gangue throwing speed, the gangue throwing height and the gangue throwing distance are improved.

Description

technical field

[0001] The invention relates to the field of coal mine filling and mining, in particular to fully mechanized mining supporting and throwing gangue filling hydraulic supports. Background technique

[0002] Waste rock filling mining, as a green mining technology in coal mines, has received more and more attention in the context of ecological civilization. Gangue filling mining can fill coal gangue underground, reduce surface coal gangue stacking and land occupation, and avoid coal gangue spontaneous combustion, rain, mud and other environmental deterioration. At the same time, gangue filling mining can also reduce surface subsidence, prevent or reduce The loss of surface water and the protection of surface ecology are of great significance to the promotion of ecological civilization. Gangue filling mining is currently commonly used for roadway filling and fully-mechanized mining filling. Roadway-type gangue filling is to use a belt throwing machine to fill gan...
