The invention discloses a hydraulic dumping control system of a dumper and a control method of the hydraulic dumping control system, and relates to the technical field of hydraulic control of engineering machinery. A displacement sensor is arranged on a frame of the dumper, the hydraulic dumping control system comprises a dumping oil cylinder, a first hydraulic control reversing valve, a gear pump, a hydraulic control pilot handle and an electromagnetic reversing valve, the gear pump provides pilot oil for a control valve of the hydraulic control pilot handle, and the control valve is connected with the dumping oil cylinder through the first hydraulic control reversing valve. A first working oil port of the first hydraulic control reversing valve is communicated with a rodless cavity of the dumping oil cylinder, and a second working oil port of the first hydraulic control reversing valve is communicated with a rod cavity of the dumping oil cylinder; the control end of the electromagnetic reversing valve is in signal connection with the displacement sensor, an oil inlet of the electromagnetic reversing valve can be communicated with an oil outlet of the gear pump, and an oil outlet of the electromagnetic reversing valve is communicated with the first hydraulic control end of the first hydraulic control reversing valve. And a first working oil port and a second working oil port of the first hydraulic control reversing valve can be communicated with an oil return port of the first hydraulic control reversing valve.
