The present disclosure relates to a method of controlling transversal resonance in a catenary of a mine drum hoist system (1) comprising a hoist drum (5) having Lebus grooves, a head sheave (7), a rope (9) having a catenary (9a) extending between the hoist drum (5) and the head sheave (7) and a vertical rope portion (9b), and a conveyance (11) attached to the vertical rope portion (9b). The method comprises a) determining a current payload of the conveyance (11), b) obtaining a hoist speed of the hoist drum (5), corresponding to a first speed of the conveyance (11), c) determining a transversal resonance position along the vertical rope portion (9b) at which transversal resonance is generated in the catenary (9a) when reached by the conveyance (11) with the current payload and first speed, wherein the transversal resonance position is determined based on the current payload and on the hoist speed, and d) reducing the first speed of the conveyance in a speed reduction zone which includes the transversal resonance position. This disclosure also relates to a computer program, a hoist drum control system (3), and a mine drum hoist system (1).
