Subject aims expressed by acquired skills and competences

Students learn in detail the possibilities of application of hydraulic actuators on the mining machine. The advantages and disadvantages of hydraulic drives and is able to compare them with electric motors. Will get acquainted with specific requirements for hydraulic drives in mines and ways to address them. Identifies the hydraulic fluid systems and lead mines are properly applied.
