Mine underground automatic coal mixing system

The invention discloses a mine underground automatic coal mixing system which can realize transferring a coal mixing process to the underground, realizes a coal mixing process while a metering hopperloads coal, reduces a special coal mixing process on the ground, is higher in proportioning precision in comparison with ground coal mixing, and realizes mixed coal outside a well mouth. According tothe following technical scheme adopted by the invention, two or more coal bins are arranged above a main well loading region, the bottom of each coal bin is equipped with a coal feeder, each coal feeder is connected with a frequency converter, and the frequency converter is connected to an upper computer through a communication cable; an adhesive tape conveyor used for coal unloading and transferring of the coal bins is positioned below the coal bins; and the metering hopper is mounted below one side of the adhesive tape conveyor. 本发明公开了种矿井井下自动配煤系统，通过该系统可以实现将配煤的工序转移到井下，在计量斗装煤的同时就实现了配煤的过程，减少了地面道专门配煤的工序，并且配比的精度较地上配煤更高，实现
