Coal mine coal gangue co-mining and partite-transport filling system and method

Abstract

The invention discloses a coal mine coal gangue co-mining and partite-transport filling system. The system comprises a filling support, wherein a filling scraper conveyor is arranged at the rear end of the filling support, a coal cutter and a working face scraper conveyor are arranged below the front end of the filling support, a groove bottom plate and a groove middle plate with a discharging opening are arranged on the working face scraper conveyor, one end of the working face scraper conveyor is in lap joint / connection with a gate road tape in a tape gate road, and the other end of the working face scraper conveyor is in lap joint / connection with the filling scraper conveyor at the rear end of the filling support. According to the coal mine coal gangue co-mining and partite-transport filling system, the problems that a thin coal seam is large in the difficulty of parallel operation of mechanized coal mining and filling, and the gangue washing cost is large are solved. According to acoal mine coal gangue co-mining and partite-transport filling method, the mined gangue can be directly separated on a working face and fills a goaf, the mining and filling parallel operation is achieved, the gangue content of raw coal is reduced to the maximum extent, the washing selecting pressure is reduced, and the environmental protection treatment and the green mining of coal gangue are realized.

Description

technical field [0001] The invention belongs to the technical field of coal mine filling and mining, and in particular relates to a coal mine coal gangue co-mining separate transport filling system and also relates to a coal mine co-mining coal gangue co-mining separate transport filling method. Background technique [0002] Thin coal seam means that the thickness of the coal seam is less than 1.3 meters. my country's thin coal seam coal reserves are relatively abundant. At present, most of the thin coal seam working faces also use fully mechanized mining for coal mining. However, due to the thin coal seam and the height of the working face is too low, In order to meet the minimum mining height of the fully mechanized mining hydraulic support, the shearer often needs to break the top or bottom when cutting coal, resulting in a large amount of gangue mixed into the mined coal, which makes the coal contain a high amount of gangue and affects the quality of the coal. Cause greate...
