Abstract
A method and a device during an emergency stop of a mine hoist for preventing the occurrence of vertical oscillations which may arise in the skips (12, 13) of the mine hoist, and wherein the mine hoist is driven by means of an electric drive system (1) and wherein the mine hoist has a mechanical braking system (3) which, in case of emergency stop, is applied via a brake application generator (2) of a control signal which is adapted such that the risk of oscillation when applying the brake is minimized, and via a control signal which is generated by the speed control of the mine hoist, and wherein the control functions are implemented in the form of programs in a calculating member (22) .
