Abstract:

Seafloor rock drill is the necessary equipment for marine geologic and environmental investigation. The present situations of deep-sea mineral resource core sampling technology and equipment were summarized, and the performance, structure and technology characteristics of several kinds of typical seafloor rock drill were focused on. The supporting and leveling mechanism technology, core sampling technology, drill string making and breaking and drill rods storage magazines technology, hydraulic system and pressure compensation technology, high voltage power supply and high-speed data communication technology by armored power & communication cable and launch and recovery technology of key technological problems of seafloor rock drill were analyzed. Based on analyses of the development of seafloor rock drill, it will develop into large-size, multiuse, intellectualization, professionalization, facilitation and truth-preserving sampling.

Key words: deep-sea, mineral resource, seafloor drill, core sampling
