Abrégé

Disclosed in the present invention are a method and an equipment for separating coal and gangue and refilling gangue. The method comprises the following steps: cutting an upper coal layer by a coal mining machine (5) and conveying the coal to a well by a scraper conveyor (1), a transfer conveyor (2) and a belt conveyor; cutting a middle gangue layer by the coal mining machine (5) and reversely running the scraper conveyor (1) to convey the gangue to a gangue back-conveying transfer conveyor (3), conveying the gangue by the gangue back-conveying transfer conveyor to a gangue throwing scraper conveyor (4) which is suspended on the rear part of a hydraulic bracket (6) and provided with an open middle slot plate and throwing the gangue into a gob; and cutting a lower coal layer by using the coal mining machine and conveying the coal to the well by using the scraper conveyor (1), the transfer conveyor (2) and the belt conveyor. The method can realize the separation of coal and the gangue, and the gangue is refilled into the gob, so that mixed mining and conveying for the coal and the gangue are avoided, the cost is saved and the environment is protected.
