Embodiment Construction
[0019] As shown in Fig. 1-Fig. 5, the present invention adopts no coal pillar mining, adopts the belt and scraper conveyor of the prior art to transport gangue, and the gangue belt throws gangue at high speed to realize the coal mine gangue filling of the mining face without coal pillar. Area. The raw gangue produced by each excavation of the mine head-on is directly transported to the gangue unloading lane 7 by a 1-ton mine car, and the gangue is turned over to the gangue bin 9 by the cantilever cart machine 8 jacked into the gangue bin 9, and a funnel is installed at the bottom of the gangue bin 9 The gate 15 is evenly discharged to the gangue transporting scraper conveyor 16 through the funnel gate 15, through the gangue transporting belt conveyor 4, the gangue transporting scraper conveyor 13 on the working face, the gangue transporting scraper conveyor 11 on the working face, Then the gangue is thrown to the goaf by the high-speed gangue belt 12. Because the filling width...
