This paper presents a solution for a propulsion system that provides perfect speed control and maneuverability for a survey launch used in the process of underwater coal mining. First, mining aspects of coal exploitationare explained. There is also a brief technical description of a cutting wheel suction dredger, including specifications for dredging equipment. Theimportant role of the survey launch in underwater mining procedures is outlined and technical specifications of an installed indirect diesel-hydraulic drive are given. A qualitative comparison between the diesel-hydraulicand the other conventional propulsion systems is made. Finally, some operating parameters of the diesel-hydraulic populsion system are given through a number of diagrams recorded during trials.
