Abstract: In order to realize the efficient transportation of gangue from ground to underground in solid filling coal mining transportation system, three different ways of gangue transportation are introduced in this paper. Taking the design of vertical gangue throwing system and gangue inclined shaft transportation system as examples, the structure design of gangue transportation system and the calculation of key parameters of gangue throwing well are discussed in detail. Finally, from the point of view of reducing the amount of gangue throwing well at the source. The design method of combined arrangement of coal and gangue separation in underground mine is discussed. Through the systematic design method, the multi-design mode of gangue transportation system is established, which provides a reference for the design of solid filling coal gangue transportation system under similar conditions.
