摘要： A hydraulic assembly for a mining system is disclosed. The hydraulic assembly may have at least one control valve for controlling a supply of hydraulic fluid to a hydraulic actuator of the mining system. The hydraulic assembly may also have at least one temperature sensor associated with the at least one control valve. The at least one temperature sensor may be configured to measure a temperature of the at least one control valve. In addition, the hydraulic assembly may have a control unit in communication with the at least one temperature sensor. The control unit may be configured to receive the temperature measured by the at least one temperature sensor. The control unit may also be configured to determine that a leakage has occurred in the at least one control valve based on the temperature.
