Spiral - Cutting Deep Cobalt Crust Mining Head For Minimum Operating Energy Consumption

Along with land mineral resources used up by human beings and we understood the ocean more and more, Oceanic cobalt crust resource has been a commercial foreground strategically resource in 21 century which was focused the international attention upon. Based on some experts' forecast, in the middle of this century cobalt crust 's commercial and comical mining would be possible.In order to keep up with the position of international seabed resources research and development, advance our project in seabed resources development, The Ocean Mineral Resource Research and Development Association of China took "Cobalt Resources Estimate and Research " (DY105-01) and "Cobalt Collection Model Key technology and Equipment Research" (DY105-03-02) as the emphases item in the 《"Tenth Five years national development program" OF International Seabed Area Research and Development》 and 《"Tenth Five years national development program" Enchiridion OF International Seabed Area Research and Development》 .Because of our capability of exploiting and developing the ocean was not as well as the developed countries, and our investment was rather little, carrying out a lot of practical model examinations which need much money in ocean would be out of the question, we must taking use of the technology of modern simulation, simulating all the course of deep sea resources exploiting technology and the key equipment, improving the research efficiency and pace of deep sea resources exploiting and development technology, reducing the risk and depressing the investment in deep sea mining.The paper was just at this position and condition, on the bases of taking technological demonstration of cobalt crust collection in deep sea and the analysis of it's feasibility, looking for a economic and efficient mouthed or technological route to collect the cobalt-enriching crust in deep sea.In the end the author regarded minimizing costs of energy as the target, adopted float genetic algorithm method to design the parameters of Cutting head. And the author programmed for optimizing the parameters of Cutting head.Although the paper was designed to work for deep-sea cobalt crust mining, the theory and methods can be used by other designs. So the paper not only seems useful to deep-sea cobalt crust mining, but also offers a new design method and powerful tool for traditional spiral drum cutting head's parameters designing.
