METHOD AND HYDRAULIC SYSTEM FOR CONTROLLING THE SUPPLY OF FLUID TO A COMBINE FOR EXTRACTING MINERALS A method for controlling the supply of fluid to a combine, wherein fluid is fed for actuating hydraulic cylinders 14, 15 of the drive for moving the combine and to a dust suppression hydraulic system 1. The same fluid, which is discharged from the hydraulic cylinders 14,15, is used for feeding it at a pre-set pressure to the hydraulic system 1 for emergence under the flowthrough conditions. For that purpose, the dust suppression hydraulic system 1 communicates, via a fluid distributor 13, with the hydraulic cylinders 14, 15 to define an open-circuit hydraulic system.
