Mining area coal bunker concrete preparing system and coal bunker building method

The invention provides a mining area coal bunker concrete preparing system and a coal bunker building method, and relates to the technical field of mine coal bunkers. The system comprises a material main haulage roadway, a belt main haulage roadway, an aggregate chamber, a coal bunker, a mining area connection roadway and a stirring chamber; the material main haulage roadway is internally providedwith the aggregate chamber, the aggregate chamber communicates with the mining area connection roadway, the mining area connection roadway communicates with the stirring chamber, the stirring chamberis located above the coal bunker, and the belt main haulage roadway communicates with the top of the coal bunker; the aggregate chamber is internally provided with a material matching device, the mining area connection roadway is internally provided with a belt conveying device, the stirring chamber is internally provided with a stirring device and a concrete chute, the upper end of the concretechute in the length direction cooperates with the stirring device, and the lower end of the concrete chute can be adjusted to any position of the side wall of the coal bunker; and by building the coalbunker through the system, continuous preparation of concrete can be achieved. Through the mining area coal bunker concrete preparing system and the coal bunker building method, the problem that during mining area coal bunker manufacturing, concrete raw materials are fed repeatedly, and material stacking is caused is solved, and the working efficiency is improved.
