Abstract: Disclosed is an integrated method for mineralizing and sequestrating carbon dioxide and filling goaf with fly ash, which relates to the engineering field of combination of fly ash and carbon dioxide recycling. The method includes: S1, selecting an area conducive to sequestration of the carbon dioxide; S2, building a stope overburden pressure calculation model in the selected area, to determine a key stratum of a stope and calculate a limit caving interval of an overlying stratum of the stope; S3, mining a coal seam of the stope, and filling the goaf, manufactured by mining the coal seam, with gangue in the coal seam; S4, fully stirring, by a stirring apparatus, the fly ash to form loose fly ash, outputting the loose fly ash to the goaf for filling, and determining an effective flow radius of the carbon dioxide by means of a built carbon dioxide seepage model; and S5, reasonably setting an interval of a vertical drilling well according to the effective flow radius of the carbon dioxide.

Abstract: A complex-connection single-gear vehicle power system includes an engine, an ISG motor, an engine transmission mechanism, an electromagnetic clutch, a drive motor, a drive motor transmission mechanism and a power output shaft. The ISG motor and the drive motor are disposed on different shafts; the ISG motor is disposed on a transmission shaft of the engine transmission mechanism, or is disposed on a shaft different from the transmission shaft of the engine transmission mechanism; the electromagnetic clutch is disposed on the transmission shaft of the engine transmission mechanism or the power output shaft, and an end gear of the engine transmission mechanism is disposed at an end of the power output shaft; and an end gear of the drive motor transmission mechanism is also disposed on the power output shaft.
