The invention relates to the technical field of hydraulic systems, and provides a hydraulic control system and an operating machine, and the hydraulic control system comprises a hydraulic cylinder, a control valve group, a high-pressure energy accumulator and a low-pressure energy accumulator. One side of the control valve set is connected with the hydraulic cylinder, the other side of the control valve set is connected with the high-pressure energy accumulator and the low-pressure energy accumulator, and the control valve set is used for controlling the communication state between the high-pressure energy accumulator and the hydraulic cylinder and the communication state between the hydraulic cylinder and the low-pressure energy accumulator. And oil is supplied to the hydraulic cylinder or the shrinkage falling potential energy of the hydraulic cylinder is recovered. Through the structural arrangement, the high-pressure energy accumulator is connected with the hydraulic cylinder through the control valve set
