An arrangement and method of underground mobile mining machine (M) for cable reeling. The arrangement comprises a reel (1), and hydraulic components, comprising: a hydraulic motor (5) connected to and for rotating the reel, a tension control valve manifold (4) configured to control tension of the cable, a pump (8) hydraulically coupled to the hydraulic motor (5) by a reeling-in line (26) and a reeling out line (27), the pump arranged to control pressure fluid flow and direction, a control device (10) arranged to control displacement and the pumping direction of the pump (8), a pump proportional valve (11) arranged to control displacement and delivery of the pump (8), and connected to the control device (10), a first throttle (22) arranged between the pump proportional valve (11) and the control device (10), a second throttle (23) connected to the control device (10). The hydraulic components establishes a closed hydraulic system, and the pump (8) is connected to a system (33) configured to generate a braking moment counteracting a moment caused by a cable (25) unwinding from the reel (1).
