The invention discloses a hydraulic control system for a long-head mine vehicle. A one-way liquid filling valve is arranged in a pressure oil output pipeline of a gear pump, and when the pressure value of the system is lower than the set value, the one-way liquid filling valve conducts liquid filling work; an oil outlet of the one-way liquid filling valve communicates with an oil inlet of a three-way ball valve, and an oil outlet of the three-way ball valve communicates with an oil inlet of a reverse adjusting pedal valve through a stop valve; and an oil outlet of the reverse adjusting pedal valve is connected with an oil outlet of a manual pump. The hydraulic control system for the long-head mine vehicle has the advantages that brake force is output linearly, so that it is guaranteed that the situation that locking occurs as soon as braking is conducted is avoided, comfortable and universal operation is provided for a user, and the adaptive capacity of the vehicle is improved; the service life of the gear pump can be prolonged substantially, and the reliability of the system is improved; by using the manual pump, a wet brake can be started emergently under the condition that the hydraulic system loses a power source, convenient maintenance of the vehicle is guaranteed, and the maintainable using performance of the vehicle type is improved; and the locking condition is avoided when normal continuous braking is conducted, and the operability of the system is improved.
