Abstract: Disclosed are an integrated mining method and an integrated mining system of coal breaking, coal extraction and water circulation in a U-well. The integrated mining system includes a first ground facility unit, a second ground facility unit, a jet unit and an extraction unit. The first ground facility unit is configured to transport jet fluid to the jet unit. The jet unit is configured to break a coal seam in a sub-segment to obtain broken cinders. The extraction unit is configured to extract a coal-water mixture. The second ground facility unit is configured to receive the coal-water mixture. In response to determining that an extraction of the sub-segment is complete, the jet unit and the extraction unit is configured to move to a next sub-segment using powers provided by the first ground facility unit and the second ground facility unit.
